Filling a Day of Social Distance – 3/22/2020

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Trying macro photographs of spicebush and red maple. My original plan was to tromp through the backyard and into the woods…do the photography outdoors. But – it was colder and breezier than I anticipated so I cut a small spicebush branch and picked up a twig of red maple samaras that had blown off. The photography part of the project would be done inside.

I worked with the red maple samaras first. I used a jeweler’s loupe and my cell phone with the samara on my kitchen countertop…a small flash light supplementing the natural light coming from one side. I like the graceful ridges in the ‘wings.’

Then I ‘got close’ with my Canon point-and-shoot camera….let its macro setting do it’s best. These are small immature samaras…about 1/4 inch.

The spice bush flowers are small too. I put the branch in a vase (with the sycamore branch). I might get to see its leaves unfurl too…after the flowers are done. I noticed an ant on the branch as I put it in the water. Can ants be pollinators?

I tried several approaches to photographing the small flowers. The ones below were done with the clip-on macro lens on my phone. The challenge is the shallow depth of field. These flowers are small but not flat!

Then I tried putting my Canon bridge camera on a tripod across the kitchen and using the zoom. It blurs the background and provides more depth…but the color is gone. Maybe I’ll put more light on the flowers and try again. The sycamore buds might benefit from the same photographic strategy. My husband gets into the action too – helping me with the more complicated set ups.

Catching up on the Cincinnati Zoo Home Safari videos:

• Moe the two-toed sloth

• Lions Imani and John

• Penguins (in a very noisy habitat…I didn’t watch the whole thing)

• Seyial the black rhino

Completing the Jackson Pollock segment of the In the Studio: Postwar Abstract Painting Coursera course. I’ve been doing one ‘week’ of the course every day and enjoying all of them – particularly the part about learning how they were made.

Re-assessing our investment strategy…making some changes. At first, we thought that maybe the social distancing strategy would work, and the economy would blip but recover soon. Not enough people are following the guidance – it says something very sad about us as a nation – and means that the pandemic with be more overwhelming. From an economic standpoint, it is more than a blip and deteriorating further. So we made some investment changes to stabilize rather than free fall…..continuing our social distancing…and hoping that the tests of potential therapeutic drugs work well enough to save lives and shorten the time people are in the hospital to recover. Both my husband and I fell of the wagon of limiting time spent following the coronavirus stories and statistics yesterday…back to limiting that activity today – no one needs a constant pounding of repeating bad news.

Jigsaw Puzzle of the Moon

Cleaning out a large box that had been in our basement since we moved to our house 25 years ago, I discovered framed pictures and other wall hangings. Several pieces were from the 1980s – a macramé piece made by sister on a large hoop and a collage of astrophotographs my husband made in the late 70s and early 80s. Other things were much older: a picture my husband remembers being in the houses he grew up in from the very beginning of his memories and a jigsaw puzzle of the moon that I remember helping to assemble in the 1960s. The puzzle was very difficult – made possible only because of the labeling of the features; my family was so pleased when we finished it that we glued it to a board. Someone carefully cut the circle and painted the raw edge black. I not sure when I ended up with it because of my husband’s interest in astronomy.

The 1960s were full of optimism about space exploration. It fueled an uptick in science and engineering interest overall. I’m glad to have this memento of the time. But where does this jigsaw puzzle go next?

Gleanings of the Week Ending March 21, 2020

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.  

Can Destroying Senescent Cells Treat Age-Related Disease? | The Scientist Magazine® - Lots of trials going on…this may be a way to extended years of healthy life (not elongate life).

This 'Blood-Red' Snow Is Taking Over Parts of Antarctica | Smart News | Smithsonian Magazine – I remember seeing snow that was the color of watermelon in Colorado…it’s algae Chlamydomonas nivalis, which is the most common type of snow algae around the world. It hasn’t been as common in Antarctica until this year.

Just a Tiny Fraction of America’s Plastic Can Actually Be Recycled, Report Finds - Yale E360 – We can’t send it to China any more…so it’s all on us to clean up our own mess. Unless and until we can get recycling working well…it’s important for all of us to reduce our use of plastics as much as possible. It’s hard to do.

States with highest rates of melanoma due to ultraviolet radiation identified: Several landlocked states among those with highest rates -- ScienceDaily – It’s not all about being out in the sun either. The prevalence was higher in younger females due to tanning bed usage by teen girls in the late 1990s contributing.

Interactive Infographic: How Salt Transforms Coastal Forests | The Scientist Magazine® - We noticed this process as we’ve visited Blackwater National Wildlife Refuge over the years. There are some areas that used to be marsh with some trees that are now open water.

Top 25 birds of the week: March 2020 - Wild Bird Revolution – No birding festivals in our future near term….but still enjoying pictures taken by others.

Why your internet habits are not as clean as you think - BBC Future – A good compilation of studies about energy consumption for various aspects of our online activities….maybe we can skew toward the lower energy use ones more frequently. Some of the energy, we pay for in terms of our electricity use….others are embedded in products or services we use where the energy usage is not something we see directly.

Chinese Mantis Egg Cases

Update: This blog post is about a visit to Robinson early in March. Like all Howard County Recreation and Parks facilities it is closed today as part of the strategy to slow the spread of COVID-19. Check the county web site for more information.

The dried grasses near the entrance of Robinson Nature Center seem to have a lot of mantis egg cases. They are easy to spot this time of year when the plants are dried and shriveled. The egg cases themselves look a bit like dried foam – about the same color as the grasses. But their shape is distinctive. It’s a Chinese Mantis egg case. The three egg cases I photographed were within a few yards of each other! There are going to be a lot of little mantises looking for food in that garden this spring since each egg case has 100s of eggs.

The species is not native, but it has been around in the US a long time. It was introduced in 1896 to the US and is now throughout the Northeast. It is the largest mantis in North America. It eats mostly other insects and spiders but has also been known to eat small reptiles, amphibians and even hummingbirds. I saw one eating a tiger swallowtail (dark morph) butterfly last July at Brookside Gardens

Filling a Day of Social Distance – 3/15/2020

I normally do a daily blog post…but during this time, I might do an extra post from time to time. Since I am ‘staying at home as much as possible’ to reduce our COVID-19 exposure (and potentially slow the spread of the virus), I have more time at home.

Normally this time of year I travel, get training for upcoming volunteer activities, and take day trips---as spring is unfurling. This year was no exception, but it all came to a screeching halt last week. So – what am I doing with this extra time at home? Fortunately, I have a house that I enjoy and there is a lot to do. If you are at home and getting a little low on ‘things to do’ maybe these extra posts will give you some ideas.

There are the usual things that I always try to work into my day (but don’t always succeed when I have a lot of other things going on):

• Zentangle (more than one)

• Breathing App (this is an smartphone app that provides tones for breathing – in and out – in a rhythm that people meditating achieve….I find it very relaxing for 15 minutes…better than a substantial nap and makes me even more focused on whatever I do afterward)

• Yoga (I’ve already built up my routine in the past week!)

• Browse through 3-4 books on Internet Archive and other online sources. (I like variety. Today I am still working my way through 1) The Vermont Life magazines – I am up to Autumn 2011; 2) Starting The English Home magazines; 3) Working backwards through the Quarterly Journal of the Audubon Society of Missouri – I am back to 2013 now…getting to know to birds found in the state where my daughter is living; and 4) Keeping in reserve the Internet Archive collection by or about Alphonse Mucha.)

• 12,000 steps (this one is a little harder being at home all the time although I am taking walks around the neighborhood or working in the yard on days that the weather is good)

• Pictures of birds at the feeder or birdbath – right now the feeder is empty because we are discouraging a hawk from frequenting our back yard and it’s been raining so the birds don’t need the birdbath as often

But what I am doing more than the usual today…what are some ‘different’ things that I did today to keep boredom at bay?

• Cleaned the foyer and kitchen floors. I don’t do this often enough.

• Dusted the top of all the door frames. It might have been over a year since I did it. They were dusty!

• Photographed the plum tree (once the rain was over). There were blossoms at different stages of development and the day was cloudy enough to avoid the harsh shadows of sunny days.

• Read a chapter in a physical book (I usually read online these days but have a stack of books I’ve been meaning to read for several years)

• Started soaking some pinto beans (the bag has been in the pantry for over a year, their ‘best if used by’ date was December 2020...I’m going to cook them to use in chili…we have plenty of time to do slow food!)

• Watched Are Viruses Alive? Video by an astrobiology professor from University of Edinburgh (recorded at home for his “Life in the Universe Pandemic Series”). I enjoyed his Coursera course several years ago.

What I am trying not to do?

• Eat more than usual

• Spend too much time looking at COVID-19 news and analysis

NISE

Update: This blog post is about a visit to Robinson early in March. Like all Howard County Recreation and Parks facilities it is closed today as part of the strategy to slow the spread of COVID-19. Check the county web site for more information.

One of the things about volunteering – there are always new things to try. Robinson Nature Center recently got some kits from the NISE (National Informal STEM Education) Network which is a community of informal educators and scientists dedicated to supporting learning about science, technology, engineering, and math (STEM) across the United States. Before I signed up for the training Robinson was offering, I looked at the NISE site. It offers many program and activities with great documentation (some kits). I was thrilled to know about the site and enjoyed the hands-on experience at the Robinson training.

Then I tried the “Exploring the Universe: Orbiting Objects” one Sunday afternoon. It included the ”gravity well” apparatus (made with PVC pipes and elbows, slip tees, PVC snap clamps, and 4-way stretch fabric). The picture shows the heaviest sphere representing the star/sun. The idea was to use spheres of various sizes and weights to simulate planets.

The activity is designed for ages 4 - adult. During the hour I was doing the activity with people coming to the nature center, the age of the children skewed young. If there were 2 children in the visiting family, the youngest was younger than 4. But it was still fun. We simply had some escaping planets and the children were not quite old enough to understand the content --- other than direct observations of the different size/weight of orbiting planets/balls and the star ‘wobble’ particularly with the heavier planet/ball orbiting. It was a learning experience for all!

Mycology Class Remnants

Way back in the 1970s when I was working on my undergraduate degree in Biology, I took a mycology (study of fungi) class. It was one of the most memorable upper level courses in my undergraduate work…but it’s been a long time. The textbook, lab book and spiral notebooks are long gone. When I was cleaning out the basement (continuing projects during the ‘stay at home as much as possible’ strategy to avoid COVID-19), I found remnants of the course: some black and white negatives in protective sleeves – unlabeled. As soon as I looked at them, I knew they were microphotographs of the microscope slides I made during the mycology lab even though I don’t remember which species they are (some are penicillium species).

The negatives were somewhat deteriorated – maybe they were never crisply focused. I scanned them with my Epson V600 Photo Scanner then clipped the best portions of some of the frames and colored them blue in Microsoft Powerpoint. They have an abstract art look.

I remember that in the lab we inoculated growth medium (agar and other types), let the fungus grow onto the glass…then stained the fungus (methylene blue, I think) to make the filaments and fruiting structures and spores appear blue under the microscope. I would love to take a mycology lab course again….and take lots of pictures!

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.  

Shrikes: Meet the Bird That Impales Prey on Spikes – The bird creates its “pantry” on barbed wire…other spikey objects. Gruesome…but it’s an adaptation that works for the bird.

The color of your clothing can impact wildlife - ScienceDaily – For water anoles – orange is better than green if you want to see the lizards!

We're Destroying Virgin Forests for Toilet Paper -- What Are the Alternatives? | CleanTechnica – Not good! We in the US are the biggest users…change is hard.

Why Clouds Are the Key to New Troubling Projections on Warming - Yale E360 – Fewer clouds as the planet warms? If so, we’ll heat up more because more solar energy will strike the planet. That’s what the most recent models are predicting and real-world data from satellites suggests that the modelers’ predictions may already be coming true. We’ll have less snow and ice around too to reflect solar energy back into space. It seems like we should make all sky facing manmade surfaces (like roofs) white or lighter colored (unless they are generating energy)…and look for other opportunities to reflect like clouds.

New Research Rewrites the Demise of Easter Island | Smart News | Smithsonian Magazine – There is mounting evidence that Easter Island people created the statues until at least 1750 – after contact with Europeans. And their population has been relatively stable since the 1400s. By the time the British explorer James Cook arrived in 1774 the statues were in ruins. By 1877, just over 100 people remained on Easter Island.

How do woodpeckers avoid brain injury? – Woodpeckers avoid concussions with some adaptions: 1) specialized skull bones, neck muscles, beaks and tongue bones 2) less internal fluid surrounding their brain to limit the motion of the brain during pecking. Interesting…and maybe can help devise ways to protect and heal human brain injuries.

Anti-solar cells: A photovoltaic cell that works at night -- ScienceDaily – Some research…potentially a way to balance solar power over the day-night cycle.

How did the last Neanderthals live? - BBC Future – From caves in Gibraltar….the insight that they were much more like us than we once believed: they exploited seafood and marine mammals (they could swim…hunted dolphins), wooly mammoths, woolly rhinos, ibex, birds (maybe used their feathers…particularly the black ones); they decorated walls and shells; their hyoid bone was like ours (which means they might have had speech like ours); they made tools of bone that were copied by modern humans.

Florida scientists study health effects from exposure to toxic algae - UPI.com – Blue-green algae toxins make people sick (liver damage/disease, skin rashes, headaches, trouble breathing) but does it cause disease when it is absorbed via breathing (i.e. airborne particles) during algae blooms? Fish kills are bad too. It’s good to research the topic but shouldn’t we do everything we can to prevent the blooms in the first place?

From the basement: pictures from house hunting in 1983

I’ve found boxes of old pictures I hadn’t looked at since we moved into our current house about 25 years ago in the basement during my increased time at home. It’s hard not to go off on a tangent and think about that history while I am scanning pictures (and/or the negatives). This post was prompted by pictures from when my husband and I moved from Texas to the east coast for new jobs in 1983. At the time there were house listings, but they were accessible only to realtors and they didn’t include any pictures. We had a week of house hunting paid for by our new employers and we were in the process of buying a house at the end of that week! We took pictures of the top contenders with a Polaroid as well as my husband’s Canon: the Polaroids to help us decide (not rely totally on our memory of each house while we were debating) and the others to develop after we got back to Texas so that we could make detailed plans on how we would arrange our furniture in the house when we moved in late June/early July.

The pictures of houses we didn’t buy are thrown away…and the ones I’m using in this post are the film photos (I was surprised that the Polaroids were still in good shape as well) of the house we bought. The house was about 30 years old and had some light remodeling. It’s the only house I’ve owned that had a gas stove…and no fireplace. It was my first house with a basement. The yard was the high point of the place: large oak and beech tress…mature boxwood and azaleas…raised beds on two sides of the back yard. The backyard had more moss than grass. It was like a green carpet. It was quite a change from the smaller trees and overall drier conditions in the part of Texas I was moving from.

My favorite aspect of the kitchen was the pantry!

OK – now I’m telling myself to get off this tangent and back to cleaning out the basement….

Daylight Savings Time

Today is the massively coordinated move to daylight savings time for most people in the US. What a bother! It’s disruptive to our already challenged biological clocks.

Some of our clocks change automatically (all the ones connected to the internet), but my husband still takes on the task of doing the ‘spring forward’ on the wall clock, an alarm clock, the stove, the microwave, etc. He leaves my car for me to do (it has two places that need to be changed!); I never changed it back to standard time last fall…so it is correct again as of today.

There seems to be more discussion of not changing clocks twice a year…but nothing happening (yet) at the Federal level and the states are limited to the option of staying on standard time according to this article published last year about this time.  There are substantial majorities in several states that would prefer staying on daylight savings time (or shifting to the time zone to the east and staying on standard time). I think that would be my preference even though staying on standard time would be by second choice. This is a case where I don’t like the status quo!

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.  

Chasing Little Frost Trees in a Prairie Wetland | The Prairie Ecologist – We haven’t have many days for me to look for frost trees here in Maryland this year. This is always a matter of taking advantage of a frosty sunny day when it’s fun to look for interesting frost formations on exposed surfaces – grass – windshields, etc.

Stoneflies and mayflies, canaries of our streams – It’s great to see an article about the adult forms of the insects we collect as macroinvertebrates (larval form) when we do water quality monitoring either quarterly or with high school students on a field trip to a river.

Earthquakes in and around Yellowstone: How Often Do They Occur? – There are lots of them! About 5 that are strong enough to be felt have happened each year over the past decade.

Top strategies for successful weight loss maintenance-- ScienceDaily - Choosing healthy food, tracking what you eat and using positive self-talk….seems like common sense, but it is not ‘easy’ and so we struggle on. It comes down to making changes for the long term rather than just for a little while. New habits are always tough but, once truly habitual, become just the way be live our lives.  

Eero Järnefelt, painter of Finnish nature | Europeana Blog – Images of the natural world in the late 1800s. Koli National Park in eastern Finland was visited by the painter frequently.

Sustainable Farming Comes to America's Heartland | CleanTechnica – Iowa farmers…leading with their actions…responding to climate and environmental changes to farm better.

Can we heat buildings without burning fossil fuels? - BBC Future – Capturing heat from nearby places…using it for heating. It’s geothermal in the cities!

Bloom in McMurdo Sound – Green swirls in the water off Antarctica (some of the green color might be on the ice as well.

Camera Trap Chronicles: Cool Critters of New Hampshire – Maybe sometime  we’ll put our camera, currently pointed at the birdfeeder, in another location….see what comes into our backyard. I know we have deer but there could be other things as well. Our camera already picked up what looked like a racoon on our deck.

Top 25 birds of the week: groups of birds – Beautiful birds…a good ‘last addition’ to the gleanings list this week.

3 Free eBooks – February 2020

Three picks from my February browsing in Internet Archive…..so many books to choose from.

Richardson, Frederick (illustrator). Old, old tales retold - the best-beloved folk stories for children. Chicago and New York: M. AAA. Donohue & Company. 1923. Available from Internet Archive here. I wonder how many children in the 1920s had access to books like this one. My guess is that the books were mostly available in cities and to wealthier families.  There is a Wikipedia entry for Frederick Richardson that prompts me to look for other books that he illustrated. The metadata for books on Internet Archive does not always list the illustrator….so searching by title or the author of the text is required.

Vermont Department of Tourism and Marketing. Vermont Life. Montpelier: Agency of Development and Community Affairs. A quarterly magazine published from 1946 – 2018…all available from Internet Archive here. I started out with the first issues and am now up to 2004. It is interesting to see how the state changed over that time. I enjoy all the seasons but picked a ‘spring’ picture since that is the season coming up.

Scott, Jeffries, Samantha (editor). Homes & Antiques. Immediate Media Company Bristol Limited. A magazine with most issues from January 2015-March 2016 available from Internet Archive here. There were several pictures with shoes stored under the bed. Now I don’t feel as guilty about not putting my shoes in the closet floor as we did when I was growing up. At least half my shoes are by the door to outside or under my computer desk!

Top 25 Wild Bird Photographs of the Week: February 2020 – Note the new website for these weekly posts: https://wildbirdrevolution.org/ ---The posts are still the beautiful bird pictures collected into a group for a weekly visual celebration of birds.

100% Wind, Water, & Solar Energy Can & Should Be the Goal, Costs Less | CleanTechnica – A short summary of a report with specifics for 143 countries…getting to 80% renewable energy by 2030 and completing the transition by 2050. Now to vote with that goal in mind for a livable future for ourselves, our children, our grandchildren….and onward.

LEDs, Downward Lights Changing the Night in Chicago - News | Planetizen – Chicago will complete the transition to energy efficient LED streetlights in 2021. They’ve calculated that it will save the city $100 million over 10 years. At the same time, they have made an effort to focus the new lights downward to cut light pollution. It’s too early to tell if that aspect of the project will be a success.

Vegetation Filters Harmful Particulates from Air--But How Much? | The Scientist Magazine® - It’s probably better to push for the transition to renewable energy (in school buses, for example) but where that is not happening fast enough – planting a green wall of vegetation can block pollution from school yards…which could reduce the impact of vehicle exhaust on children’s lungs.

Decline in Coal-Fired Power Reduces U.S. Carbon Emissions in 2019 - News | Planetizen – Good news…but it could decline more quickly. The 2019 results are from market forces alone. If there were political will, things would happen even faster.

Archaeologists Excavate 200 More Chinese Terracotta Warriors | Smart News | Smithsonian Magazine – The first terracotta warriors were found in China’s Shaanxi province in 1974. Now there is more excavation and more soldiers from the same tomb. All the warriors have unique expressions, hairstyle and physical features.

Organic crop practices affect long-term soil health -- ScienceDaily – This study looked closely at organisms in the soils…along with the impact of prior soil disturbance.

Recovery: A Plague of Bullfrogs – The Eastern part of the US is the native range for Bullfrogs…but they are invaders in the West. They are clearing native frogs and eating other animals too (ducklings are an example cited). So various municipalities and conservation groups are acting.

What We Can Learn From Ötzi the Iceman's Hunting Pack | Smart News | Smithsonian Magazine – Ötzi was preserved for 5,300 years in a glacier until he was discovered in 1991. A lot has been studied since that time. He’s a window into Copper Age Europe.

Photography in the National Parks – More favorite spots for photography from Rebecca Larson. This collection included three National Parks I have not visited: Glacier, Olympic and Mount Rainier. Now I want to plan a trip to see them!

Laredo Birding Festival Day 2

We were up at 4:30 AM to prepare for our day of birding at the Laredo Birding Festival. After a delicious breakfast buffet we boarded the van shortly after 6:15 AM and headed to the Yugo Ranch - currently owned and operated by 6th generation descendants of Ygnacio Benavides, who live by the same conservationist philosophy as their ancestor – where we would spend the morning and early afternoon. We parked the van near the ranch buildings, and everyone bundled up since it was a cold morning.

There was a Texas Ebony tree near where we parked. There were a lot of seed pods on the ground around the tree. The birds and other wildlife had already finished off the seeds.

All during the morning we saw Vermilion Flycatchers – the bright red attracting attention.

Crested Caracara flew overhead and there were a pair in a tree just barely within the range of my camera.

When we made a loop back to the ranch buildings, I managed to photograph a wren which was easily identified later from the picture as a Cactus Wren. It seemed to be very interested in the chimney.

We drove out to look at some ponds on the ranch…and spotted a familiar bird: a Killdeer.

There were also Great Kiskadees like we saw several years ago during the Rio Grande Valley Birding Festival.

There were groups of Northern Cardinals…a small flock. In our area of Maryland they are usually only seen in pairs or males contesting turf…the small flock was new to us.

The high point of the morning was a Great Horned Owl. It was surveying the area from a tree growing on an island of the pond. It sometimes looked our way….decided our group was no threat at all.

Looking closely at the picture I took of a cormorant – I realize that it is a Neotropic Cormorant (rather than a Double-crested Cormorant) because the eye is surrounded by feathers rather than a bare patch of skin.

There was an American Wigeon just barely within the range of my camera zoom.

As we headed down the road in our van, there was a Curve-billed Thrasher in the road. I was ideally positioned to take pictures through the windshield of the van!

Also on along the road, a Pyrrhuloxia was spotted. For this picture I had to contort a bit to get the picture through a side window.

We had been seeing Harris’s Hawks and I finally got a picture of two that were near each other on a telephone pole. This species hunts as a team!

​The next stop was Ranchito Road Lagoons. The high point of the afternoon happened at this location: American White Pelicans feeding in unison. I had not seen this behavior before. It was like a ballet and they did it for the whole time we were at the location.  

A Black-necked Stilt and

Lesser Yellowlegs were feeding in the shallows.

On the way back to hotel we stopped at the Laredo Landfill. It was very windy (dust and some trash flying everywhere) so we didn’t stay long. There were quite a few Cattle Egrets huddled together near the entrance. And lots of Chihuahuan Ravens that were closer to where we stopped. I later wished that I had walked over to get a picture of the Cattle Egrets since we didn’t see them in any other festival location.

What a productive day of birding around Laredo!

Laredo Birding Festival – Day 1

My husband and I flew to San Antonio (me from Dallas, he from Baltimore) and drove down to the Laredo Birding Festival from there. We made a rest stop at the Lasalle County Rest Stop (southbound) and

Immediately saw our first stunning bird of the trip: A Greater Roadrunner. It was in the picnic area of the rest stop and then moved out into the parking area. It was a cold day, so the feathers were fluffed making it look plumper than usual.

The rest stop had well maintained plantings – some were blooming in the cold.

The signage and windmill outside the building started the historical story of the county.

Inside the building were displays about the county: ranching, railroad, mining and farming. On the back of the hanging signs were metal sculptures that I enjoyed.

As I got ready to write this blog post, I checked Google maps for the rest stop and discovered that there is a short hiking trail to the south of the rest stop. I’ll walk around it next time I am make that stop (maybe next year).

We got to Laredo and checked into the La Posada Hotel which would be the hub for departures on the trips for the festival. It’s very close to the Rio Grande….in the older part of Laredo. A hour or so later we walked to the Laredo Center of the Arts for the 2020 Birds of the Brush exhibit – bird themed art from local schools. I liked the paintings on paper shopping bags and birds I recognized. The backgrounds were often what made the work memorable beyond the bird itself.

We made a light supper on the luscious appetizers upstairs…getting a view of exhibit from the glass fronted elevator as we went up from the exhibit floor.

Overall – a great start for the Laredo Birding Festival!

Traveler Special Report: Threatened and Endangered National Parks – In Alaska and beyond…we are losing the natural treasures we sought to protect.

The history of candy canes and why they taste so cool – I am late getting around to including this in the gleanings list. I like peppermint candy year round…even if it’s not in the candy cane shape! I have peppermint candy chips to use in snow ice cream…if it will ever snow enough this winter here in Maryland!

Largest Electric School Bus Program in United States Launching in Virginia | CleanTechnica – Dominion Energy partnering with Virginia School districts…to achieve a 50% electric school bus fleet by 2025 and 100% by 2030. Good for the environment and the lungs of Virginia’s school children. I hope other states will move in the same direction.

These infrared images show just how alive butterflies’ wings are – Surprise! Butterfly wings have living cells not just membranes and scales! The living cells can sense heat and the butterfly responds behaviorally.

 Flame retardants and pesticides overtake heavy metals as biggest contributors to IQ loss - ScienceDaily – There are a lot of things that are toxic in our environment these days…and children are the ones that are hurt the most…and the hurt lasts their lifetime. This study looked specifically at lead, mercury, poly-bromated diphenyl ethers (PDBE…flame retardants) and organophosphate pesticides.

Top 25 Wild Bird Photographs of the Week: Bird Photography – A little eye candy to end the list of gleanings for this week.

30 Years Ago – February 1990

30 years ago this month - Our household was beginning to make changes to sustain itself with a baby that was increasingly active. In February she became even more adept at rolling, got two baby teeth and began eating in the highchair (colorful food like carrots seemed to be favorites). About the time the first teeth came in, her tongue thrust became much less pronounced. She managed to hold things in her hands for longer periods….and we managed to capture the first picture of her with a book. She was awake and interacting much more during the day…and sleeping through the night most of the time.

My husband and I were planning our first mini-vacation with the baby before family visits to our house started in March. It was going to be tacked onto a trip he needed to make for work. I was already beginning to wean the baby and plan what I needed to do before I started back to work part-time in May. I didn’t want her to associate weaning with me suddenly being gone.

At the same time, my husband and I were finally acknowledging the stress we both were experiencing after being a couple for over 15 years…and adding a baby in the mix. The transition was harder than we anticipated but it was beginning to improve by the end of February because we were finally acknowledged that we needed to actively work on it.

Gleanings of the Week Ending February 8, 2020

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Abstract Aerial Photos of Iceland's Rivers Look Like Watercolor Paintings – A little art photography to start out the gleanings this week.

Tomb Containing Three Generations of Warrior Women Unearthed in Russia | Smart News | Smithsonian Magazine – Evidently research is revealing that warrior women were the norm, not the exception, in Scythian culture. Scythians lived in small tribes, wore trousers (practical since they were on horseback much of the time) and fought with bows and arrows.

Protecting the Sonoran Pronghorn from Extinction – It’s complicated….lots of agencies involved….an international border that is becoming a migration barrier.

Is Notre-Dame Too Fragile to Be Saved? | Smart News | Smithsonian Magazine – Removing the scaffolding that was melted by the fire is evidently going to be a big challenge.

Whooping cough evolving into a superbug -- ScienceDaily – The research was done in Australia…but it probably applies to the US as well. Bottom line: we need to be developing an improved whooping cough vaccine.

One Reason Colorado Playgrounds Are Looking Way More ‘Natural’ | Colorado Public Radio – I like the new types of playgrounds….more than swing sets and slides…bringing in some natural elements.

White Sands National Monument Redesignated As A "National Park" – A beautiful and unique place. I’ve only been there once…but it was very memorable. The biggest surprise for me was that even on a hot day in June, the sand was not hot! Being white really does reflect the heat up and away.

2019 Year In Review: Some Great Photo Tips – So many beautiful places to photograph….take some time in a natural place (National Parks are awesome…but there are other places that are great too).

Striking Portraits of Rare and Endangered Birds by Tim Flach – I tend to like bird pictures from the wild…but these are amazing portraits. Virginia Cardinal – I was surprised to see it in this grouping…as far as I know they are not different than the Northern Cardinal. Cornell’s Allaboutbirds doesn’t have a listing for them.

Mealworms safely consume toxic additive-containing plastic -- ScienceDaily – Not an answer to the plastic problem…more like basic research that could be incorporated into a partial solution. The biggest gain comes from dramatically reducing single use plastics.

eBotanical Prints – January 2020

There were only 7 botanical print books in January because I shifted focus to volumes about shells last month. I finished up the ‘Illustrated dictionary of gardening’ volumes…enjoyed the drawings in a botany textbook by Asa Gray…marveled at how different woods look at the micro level.  The last two books (Familiar Trees) are from a series that I found back in 2015…but somehow I only looked at one of the three volumes then.

The volumes are all freely available on the Internet. The whole list of more than 1800 books can be accessed here. Sample images and links for the 7 new ones are provided below. (click on the sample image to see a larger view) Enjoy!

Gleanings of the Week Ending February 1, 2020

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Unusual Urban Bobcat Spotted in Washington, D.C. | Smart News | Smithsonian Magazine – Wow! There is more open area where I live (between Washington DC and Baltimore)…maybe there is a bobcat around here too.

Low doses of radiation used in medical imaging lead to mutations in cell cultures -- ScienceDaily - Discovery that radiation creates breaks that allow in foreign DNA must be confirmed in animal studies. Maybe this is just a pathway to learning more about how cells cope with natural amounts of DNA damage….or maybe we need to look again at the risk/benefit of some routine diagnostic testing.

Stunning Chronophotos of Powerful Osprey in Mid-Hunt – Very dramatic!

Surprising Beauty Found in Bacterial Cultures – The video is less than a minute…worth watching.

Top 25 Wild Bird Photographs of the Week: #Feeding – National Geographic Society Newsroom – They all must eat. I kept track of what they were eating in the pictures: snail, insect or other small invertebrate, frog, rodent, fish, lizard, algae, carrion, nectar, skink, or seeds.

Walnuts may be good for the gut and help promote heart health -- ScienceDaily – I like walnuts….now just to eat them more consistently!

HEADING TO THE FOREST: Bringing Joy, Accomplishment & Hope to Children | Children & Nature Network – Forest days for kindergarteners and nature kids from preschool to high school…backyard to back country. More examples of how education in nature is happening. This was part 2…the earlier article can be found here.

America's most widely consumed oil causes genetic changes in the brain: Soybean oil linked to metabolic and neurological changes in mice -- ScienceDaily – Start reading labels….there is soybean oil is in a lot of processed foods like mayonnaise and salad dressings….the list goes on and on. Evidently other soy products (edamame, soymilk, tofu, etc.) don’t cause the same changes observed with soy oil.

Blue Jay: A New Look at a Common Feeder Bird – Our feeder is not accessible to blue jays….but we see them at our birdbath frequently….and hear their calls in the forest and our yard trees.

Macro Photography Shows Stunning Details of Carnivorous Plants – Some botanical pictures to finish out the gleanings for this week.
