First Day of 2020

I got up early enough yesterday to see the sunrise. The clouds were too low and thick for it to be a great one…but it was the first of 2020. I did the same thing last year….with clouds making the color smudgy.

2020 01 IMG_2103 (23).jpg

We decided that the clouds were going to clear off enough to make a trek to Conowingo Dam to see the bald eagles worthwhile. It was a cold morning, so we wore snow pants and took hand warmers. As we drove in, I noticed the seagulls first; we hadn’t seen any gulls last time we went to Conowingo (in late October). As I got out of the car, I heard some eagles and saw one flying with a stick. It circled around and went up to the platform near the top of an electrical tower. I later zoomed in for a picture of the sticks accumulating for the nest. There was a nest there in previous years so the pair may just be adding new sticks…making sure the sides are high enough to contain the chicks until they are ready to fledge.

2020 01 IMG_2103 (1).jpg

The water was high from recent rains and the dam was generating power. Both gulls and eagles were benefiting from the fish available – stopped by the dam. We didn’t see any cormorants or great blue herons this time.

2020 01 IMG_2103 (3).jpg

The eagles were active but very far away on the rocks and abutment…swooping above and into the water for fish. It is very close to out of range for my camera so most of my pictures are a little blurry.

2020 01 IMG_2103 (2).jpg

There was an interaction between two birds on the abutment. They both looked rounded with their feathers fluffed and I wondered if it was from their ‘argument’ or just being cold.

Another interaction – two juveniles. One was on the rock but flew off just as the other came in for a landing.

Another juvenile was fishing…but didn’t manage to land a fish in this foray.

My husband’s camera did a bit better. He managed to photograph an adult catch a fish, jostle it into position, be chased by a juvenile…and then take the fish up to the nest. Was there a mate at the nest? We couldn’t see.

He also got some good pictures of juveniles; we are both beginning to appreciate the wing patterns of the juveniles – lots of variety in their look before they get their adult plumage.

I took a picture of one of the two cranes that are on the top of the dam facing the lake. I assume they are used to get large debris that washes down the Susquehanna from points north out of the water.

In Search of Australia’s Amazing Rainbow Finch – A bird survey experience…and some pictures.

Patchwork of Corn in the Snow – As of late November a lot of corn was unharvested because it was too wet. Corn needs to dry on the stalks before it is harvested and this 2019 crop may not be harvested in some areas until February or March of 2020.

Watching Wildlife on Skis – Winter wildlife….another benefit to being out and about (with proper gear) during the winter.

Real Reindeer Are More Amazing Than You Ever Imagined – Another Christmas themed post…about an iconic animal that isn’t just a cartoon.

5 Free eBooks – December 2019

I usually pick 3 books to feature in the monthly ‘free eBooks’ post; this month I am featuring 5. The titles all begin  “An Artist in…” and there were published between 1910 and 1915 although not by the same publisher. I think of them as a window into 5 places just before World War I: Spain, Egypt, Italy, Corfu and the Riviera. I am reminded that artists tend to correct ‘imperfections’ as they paint…even if they are trying for realism! Enjoy the scenes from over 100 years ago!

Camera on the Birdfeeder

The new ‘toy’ we are playing with over this holiday week is a camera on our birdfeeder!

2019 12 IMG_6651.jpg

So far, we’ve been experimenting with temporary mounting on ladders to decide where to position it more permanently and adjusting parameters. The camera is not very big physically (the white blob on the right side near the top of the ladder is the camera).

Camera_01_20191217093522_20191217093529-2_Moment(2).jpg

This was my first image I clipped from one of the videos – a female red-bellied woodpecker.

I’ll get better with my editing over time. It’s very different than my usual pictures through my office window.

Ever see a squirrel climb a ladder? This one climbed right up to the camera after it was unsuccessful in dumping the seed from the bird feeder!

Next steps are to mount the camera from the eve of our covered deck and put out the small solar panel to help keep it charged. I’ll share some the technical details of our set up…once we get it working a bit better. My husband and I are enjoying the project!

Top 25 Wild Bird Photographs of the Week: Waterbirds and Camouflage and Forests and Birds in Pairs – Starting out this week’s list with some bird pictures….catching up the backlog

Liver cancer deaths climb by around 50% in the last decade -- ScienceDaily – Survival rates are low too. Obesity and smoking are two preventable causes.

How Climate Change Will Affect Maryland's Birds | Audubon – I looked at the page for Maryland because that is where I live. The red-headed woodpecker is on the ‘high vulnerability’ list. The data is available for other states as well (scroll down on the ‘home’ page and select by state or zip code). The red-headed woodpecker appears on the high vulnerability list for Texas and Missouri too (those are two other states I checked).

First Global Map of Saturn's Moon Titan Reveals Secrets of Earth's 'Deranged' Twin | Smart News | Smithsonian – There are plains, sand dunes, mountains, labyrinthine valleys…and lakes of methane.

'Self-cleaning' concrete could keep buildings looking new -- ScienceDaily – Maybe a new building material…but can it be made in a ‘green’ way?

Everything You’ve Ever Wanted to Know About Turkeys – I’m just catching up on some reading…this would have been more appropriate for the Thanksgiving week gleanings…but better late that never. Turkeys are interesting birds!

Air Pollution Tied to Brain Cancer: Study | The Scientist Magazine® - Combustion-related nanoparticles can reach our brain! The concentrations of these particles in highly polluted areas are also causing other health related problems as well. For example, the air pollution in Kabul, Afghanistan may be causing more deaths than war in that area

Owling: A Field Guide to Finding Winter Owls – Seen any owls? They are often easier to hear than see.

Slideshow: Images from The World Beneath | The Scientist Magazine® - A few pictures from a new book about sea creatures and coral reefs. Lots of vibrant color and camouflage.

Eating in sync with biological clock could replace problematic diabetes treatment: An early-morning, carb-filled meal improves glycemic control among diabetics -- ScienceDaily – We are shifting our meals…largest one at midday…smallest one at night. If we eat a high carb meal it will be at breakfast. I had gingerbread cake this morning!

Flying Wild

Last Friday – I was in Annapolis for a Flying Wild class offered by the Maryland Department of Natural Resources. It was a day to learn some activities that celebrate birds designed for age groups I normally encounter as a volunteer and Maryland Master Naturalist. The forecast for the morning drive was a little threatening (freezing rain) but it didn’t materialize. It was my first time at the Tawes State Office Building where the class was held do I took a few minutes for pictures of lobby area of the building (it was rainy and cold so no outdoor pictures): Maryland symbols, a frayed Baltimore Checkerspot (which is very rare these days), a garden drawing on one of the windows looking out onto a real courtyard garden and a sculpture of a tree planting.

We did a sampling of the activities available from Flying Wild. One of my favorites was nest building. In teams of 3, we used wire to make a frame for a nest and then used materials that we had scored for strength, flexibility, and space filler. We could use as much material as we wanted except for clay; we were only allowed a golf ball amount of that. After we constructed our nest, there were tests: 3 marbles were used as ‘eggs’ (did they fit in the nest and not roll out when the nest was shaken); then some weights were put into the nest to simulate the growing chicks. It was a lot of fun and our nest ‘passed.’ We all gained a healthy respect for birds building nests with just their beaks and feet!

20191213_122639.jpg

Of course, I come home with lots of stuff – handouts and the book…a poster and a ‘prize’ for being on the winning team for the nestling feeding relay. There were Black Eye Susan Seeds to plant next spring too!

I’m already thinking about doing some of the Fly Wild activities with summer campers!

Why biodegradables won’t solve the plastic crisis - BBC Future – There are only pieces of a solution at this point….nothing comprehensive. It seems like the best strategy for at home is to reduce all single use plastic as much as possible. There are some easy things like reusable shopping and produce bags, but it becomes hard quickly. So many groceries and toiletries only come in plastic containers.

Remote Sensing Data Advances Soil Health Science – Cover crops and no-till practices were an advantage in record-breaking rainfalls of spring 2019.

How the House Finch Conquered Your Feeder…and A Continent – A little history of House Finches – originally from the southwest and Mexico…now in found widely across North America.

How the Aztecs could improve modern urban farming: Chinampas: An old technique might provide new solutions to sustainable urban agriculture -- ScienceDaily – The article made the multiple harvests per season seem feasible in tropical wetlands…not so much in the temperate zone where the artificial islands would go through a real winter although maybe it would just mean the use of cover crops during that time period.

Top 25 Wild Bird Photographs of the Week: December – Bird photography to enjoy!

Listening to Nature: The Emerging Field of Bioacoustics - Yale E360 – An up and coming technology for remote sensing of birds, insects, frogs and other animals.

Maryland Water Monitoring Council Annual Conference

The 25th MWMC Annual Conference was held last week. It was my third time to attend and it was, once again, a great opportunity to catch up on water-related research and Maryland specific plans, activities, and accomplishments. The two themes in the sessions I chose to attend were watershed health and remote sensing. I am hoping the agenda with links for the presentation material will come out soon since my note taking is not all that legible.

I also enjoyed the vendor tables. One of the companies that did the stream restoration at Howard Country Conservancy’s Davis Branch had a table – and a post card picturing the project (before last summer’s drought)!

20191206_131411.jpg

One vendor had a great ‘Got Bugs? Banner and another had macroinvertebrate stickers.

20191206_131419.jpg

There were other giveaways too – lip balm, pens, a frog shopping bag, and a folding card Field Guide to Aquatic Macroinvertebrates.

Red Tides Under the Microscope | The Scientist Magazine® - It’s surprising what we don’t yet know about the organism responsible for red tides – Karenia Brevis. Spanish explorers of Florida in the 15th and 16th centuries described fish kills in Gulf waters. The first official documentation was in 1882 – published in the Proceedings of the US National Museum. This article is about what we know….and where more research is needed.

The woman who reshaped maths - BBC Future – Hilda Geiringer…a refugee from the Nazis. A BBC Future column celebrating a ‘missed genius’ whose contributions are still notable in the world today.

NOAA weather balloons find no zero-ozone regions above South Pole during 2019 ozone hole season | NOAA Climate.gov – A little science…a little history…a projection. The positive message – if the trend continues, it’s estimated that the ozone layer will recover around 2070.

Abrupt shifts in Arctic climate projected: Likelihood of an abrupt increase in wildfires also noted -- ScienceDaily – With specific modeling of permafrost as it continues to degrade….it appears that the changes won’t be as gradual as  previously assumed.

Lake On Bottom Of Halema‘uma‘u Crater At Hawai'i Volcanoes National Park Now Bigger Than Football Field – The lake was noticed back in July….and is being studied with instruments on drones. More information is at the National Park Service site for the park.

Top 25 Wild Bird Photographs of the Week: Wild Birds – National Geographic Society Newsroom – I always enjoy the bird photography compiled by National Geographic every week.

Offshore Wind Has the Potential to Fulfill Global Electricity Demand 18 Times Over - Yale E360 – Hurray for this potential….the transition is the challenge.

AP: At least 1,680 dams across the US pose potential risk – There is a link to an interactive map that shows where the 1,680 dams are located. The last paragraphs of the article are the most troubling. There are a lot of dams with unknown status. Roughly 45% of Texas dams are exempt from regulation…in Missouri safety inspections are only done on 650 of its more than 5,000 dams. And states that know about problematic private dams often can’t identify the owners to address the dam’s issues.

Aging in good health: The inequalities are widening -- ScienceDaily – A study with over 11 million people tracked for 25 years!

Susquehanna Sediment in the Chesapeake Bay – Imagery of big rivers and the Chesapeake Bay after a storm at the end of October…. close to where I live. On a positive note - the sediment (even after the record rains earlier this year) has not damaged the underwater grasses on the Susquehanna Flats as much as was initially feared.

eBotantical Prints – November 2019

All the books added in November were from the same authors. Charles and Edouard Morren were a father and son. They produced 35 volumes of La Belgique Horticole from 1851-1885. Both men died in their early 50s and there was no continuation of the publication after the death of the son.  This monthly post has sample images from 28 of those volumes and I will continue the series into December (posting the images for those volumes in early January). The illustrations are quite varied. They are often illustrations rather that full botanical prints – still beautiful and particularly appealing this time of year when our gardens here in Maryland are mostly brown. I’m looking forward to the upcoming volumes. The list for the individual volumes from this month is after the sample images; for a list of all the volumes Internet Archive has – check here.

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 28 new ones are provided below. (click on the sample image to see a larger view) Enjoy!

US-born residents more than 5 times likely to use prescription opioids than new immigrants -- ScienceDaily – Evidently new immigrants are often healthier than non-immigrants despite their poorer background….which is a clue that there is something about American culture that influences opioid use.

Top 25 Wild Bird Photographs of the Week: Spectacular – National Geographic Society Newsroom – Enjoy the birds! We are enjoying the birds coming to our feeder and (heated) bird bath…in the trees around our house. They are easier to see now that the leaves have fallen from the tees.

50 Fish, 50 States: Small Stream Wonders – Cool Green Science – Lots of small fish! When we are in the streams with high school students, we often find small fish but since they aren’t what we are looking for – we simply put them back without identification. Maybe I should look for a simple small fish ID to take a long and start to photograph them too.

A Giant Treehouse 'Like A Castle' Is Destroyed By Fire In Tennessee: NPR – My sister and I visited this giant treehouse in 2012 when we were in that area of Tennessee. Sad that it’s gone.

When Turkeys Attack – I’m glad the wild turkey population is recovering….hope we can develop strategies to co-exist!

Scientists study impact of sediments and nutrients from Conowingo Dam on Chesapeake Bay -- ScienceDaily – Close to home. The base of Conowingo Dam is where we go to view Bald Eagles. There is a lot of concern now about the sediment build up in the reservoir --- state governments and the utility are working to determine best options for prolonging the energy generation capacity of the dam and improving water quality into the bay.

Big Box Stores Leading the Shift to Renewable Energy - News | Planetizen – Wal-Mart and Target are all in….what about other big box stores? What about owners of shopping centers? Lots of stores are in leased spaces.

Five Architectural Firms Retained to Redesign National Mall Tidal Basin – Another ‘close to home’ in this set of gleanings. This one is in the District of Columbia. Think of the Jefferson Memorial and the cherry blossoms. Flooding has increased over the time we have living in this area (now over 35 years). Hope they can develop a good design and get the funding to implement it.

Manta Ray Populations Have Complex Social Structures | The Scientist Magazine® - A study of the reef mantas as they aggregate around the reefs of the eastern Indonesian archipelago Raja Ampat. The study showed two distinct groupings: one dominated by older females and the other a mix of sexes and ages.

Staunton River State Park sunset and sunrise

Continuing the posts about our trek to the Chaos Star Party at Staunton River State Park….

The sunsets were not spectacular because the sky was clear. I took a few pictures the first night we were camping just before sunset…when the light on the trees was golden and the campground was buzzing with activity – getting telescopes and other equipment set up for observing.

The last morning in camp was the best sunrise – because the clouds were rolling in. The forecast was for the clouds to remain for the duration of the star party and we were going to pack up. These pictures were taken from the door of our tent. It was a cold morning and I went back in to drink hot tea, put my feet on a warmer pad, cover my legs with a flannel sheet…huddled in my camp chair to eat some breakfast and read.

Once the sun came up there was enough direct sunlight through the clouds for, the tent to warmed up and the dew to start drying. It was still cold outside the tent. The deflated our mattresses and stuffed the sleeping bags into their containers. By 11 AM we were loaded up and heading to the showers to clean up before we started the trek home.

Happier Babies Have an Edge - Scientific American Blog Network – The more children experience happy emotions, the more time they spend building skills and relationships that help them in the future.

900 Pythons Removed from South Florida – That’s a lot of snakes. Kudos to the Python Action Team. There are other organizations (government and non-profits) working on this too. I wish the article would have included information about what they do with the snakes after they are captured. Presumable they are killed.

Study: 95 percent of baby food contains traces of toxic metals - UPI.com – Not good. The full report referred to in the article is available here. I wonder if pediatricians are changing their recommendation when it comes to some foods (like rice cereal for babies).

There were various signs for the star party in the areas of the park dedicated to it. The field was full of tents and campers and trailers. We were in our roomy tent with a screened area for my husband’s electronics and chair….with the telescope just a few steps away. Some people probably were staying in the cabins and coming to the field with their telescope at night. We preferred a place to sleep near the telescope…makes it easier to lay down once the clouds roll in or the dew gets too heavy for observing. My husband had two clear-sky nights and had some observational successes (I slept relatively well through it all).

Someone did an excellent job with a pumpkin near the cantina.

We managed a short hike. We’d been hearing a lot of birds, but they must have been migrating through – stopping for the night on the water. They’d flown off by the time we were up and about. We did see a juvenile Red-headed Woodpecker making a hole in a dead branch (hanging upside down). I didn’t know what it was until after I got home and could check references. It was the drabbest woodpecker I’d ever seen! It will eventually have the distinctive red head.

The woodpecker was in some trees that were around the cabins at the park. Most of them were oaks and the acorns were plentiful….lots of food for the woodpecker and squirrels. There were some other nests around too but we weren’t seeing many other birds.

The sweet gums were full of color – reds and yellows. And the seeds…prickly.

A Great Blue Heron was one of the few birds we saw on the water. It was at the limit of the zoom on my camera.

I turned around on the beach and caught some motion in the leaves. A spider moving over the sand and onto a leaf where it was not as well camouflaged.

On the way back we noted the solar system model that has been set up starting with the sun (yellow orb) close to the observing field and extending along the road.

The morning we were getting ready to leave there was a sun dog. What a great serendipity for our last morning at the park!

eBotanical Prints – October 2019

It took be almost 3 months to few all the Revue Horticole volumes available on Internet Archive. The last 26 were in October! This month includes primarily volumes from 1897 to 1922. The last volume I looked at was from 1860 which did not have color plates (or maybe it was the scan that made everything black and white. This publication was for gardeners…encouraging introduction of new plants into the gardens of France. This publication was for gardeners…encouraging introduction of new plants into the gardens of France. Some of the plants would require conservatories or greenhouses…others were new varieties of vegetables (see the potato plate).

The volumes are all freely available on the Internet. The whole list of almost 1800 books can be accessed here. Sample images and links for the 30 new ones are provided below. (click on the sample image to see a larger view) Enjoy!

Gleanings of the Week Ending November 2, 2019

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.

Eavesdropping on Soil Insects Could Aid Pest Management – Earlier this week I was hiking with second graders…soil auger in hand. There was big excitement when one of our samples include a beetle grub! And then this article appeared a few days later. The grub moved a bit and I wonder if it was one that made stridulations (chirps); if so – they weren’t loud enough for us to hear.

A Field Guide to Elk Bugling – Cool Green Science – Elk are not just in the western US. They have been reintroduced into the east.

Top 25 Wild Bird Photographs of the Week: Birds in Flight – National Geographic Society Newsroom – Some familiar birds in this group – norther shoveler, northern pintail, red tailed hawk…some others.

Could Brain Activity During Sleep Be a Biomarker for Alzheimer's? | The Scientist Magazine® - The study only included 31 individuals…so replication with larger samples is still needed. We do need a non-invasive and early way to diagnosis Alzheimer’s.

Edge of the Ice – Brown bands at the edge of the ice are layers of ice deposited at different climate periods. Usually we only see the layers in ice cores.

Better way to teach physics to university students -- ScienceDaily – Kudos to the physicists and educators at University of Kansas. Hopefully other universities and maybe high schools can benefit from these ideas.

Climate Change Threatens Hundreds of North American Bird Species: “It’s a Bird Emergency” - Yale E360 – This on top of the declines we’ve already seen in insects and birds that feed on them. The ‘bird emergency’ is not a future event…it is already happening.

New test diagnoses Lyme disease within 15 minutes -- ScienceDaily – It would be great to have a faster test for Lyme disease. Most people are probably not tested until they have symptoms…and that’s sometimes too late to avoid permanent damage.

The peculiar bathroom habits of Westerners - BBC Future – A little cultural dissonance…that we don’t often hear about.

Humans have salamander-like ability to regrow cartilage in joints: The process could be harnessed as a treatment for osteoarthritis -- ScienceDaily – Wow! If works, there will be a lot fewer joint replacements as people get older….and moving would a lot less painful.

Gleanings of the Week Ending October 26, 2019

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.

Scientists Find Way to Fully Recycle Plastics Without Losing Quality - Yale E360 – I hope this process undercuts plastic manufacturing from fossil fuels…plastics should not be the glide path for the oil companies! The heating of the plastic to 850 degrees for this process should be done with renewable energy. And what happens to the parts that don’t get recycled (I assume there is waste from the things that weren’t plastic that got into the stream (i.e. ‘dirty’ containers).

Top 25 Wild Bird Photographs of the Week: Bird Interactions – National Geographic Society Newsroom – Birds with other birds (not always the same species).

Maya Tomb of the Unknown Red Queen - Red from cinnabar (mercuric sulfide) power that covered everything inside the limestone sarcophagus…a mask of malachite.

Time Spent in Nature Is Good for You | The Scientist Magazine® - Spending at least 2 hours in nature per week is strongly correlated with self-reports of being in good health and having high well-being…..based on a study in the UK with 20,000 participants between 2014 and 2016. Intuitively – the idea seems right. But what does ‘time spent in nature’ really mean and what is it that causes the correlation? Do you have to be outdoors or is viewing it enough? I am outdoors in beautiful natural places (gardens, forests, seashores, rivers and lakes) so frequently…the 2 hours per week is at the low end for me…except for the coldest or wettest weeks.

Cooking food alters the microbiome: Raw vs. cooked diets have distinct effects on both mouse and human gut microbes -- ScienceDaily – No recommendations from this research but lots of prompts for further research.

The Short List Of Climate Actions That Will Work | CleanTechnica – These are country or continent type actions like: electrify everything, overbuild renewable generation, build continent-scale electrical grids and marks, fix concrete, change agricultural practices, shut down coal and gas generation aggressively. Some of them can be impacted by individual decisions…to move in the direction. For example – 1) The CSA I belong is on a path to not use plastic to control weeds and retain moisture around their crops. 2) The next house I buy (in the next 2-3 years) will be all electric and have solar panels…maybe battery storage too….maybe geothermal heating/cooling. 3) The next car I buy will be an EV rather than a plug-in hybrid like I have now. And I can change my yard into a mini-forest (of redbuds, dogwoods, spice bush, hollies….not huge trees but ones that are native to the area where I live).

Air Pollution May Damage People's Brains | The Scientist Magazine® - Mortality, respiratory health, cognition, and social behavior. This is scary. This is yet another reason to move away from fossil fuels.

Humankind did not live with a high-carbon dioxide atmosphere until 1965 -- ScienceDaily – I was in 5th grade in 1965. It was the grade between two memorable events: seeing a tornado just before it touched the ground and traveling with my parents to Mexico City for a weeklong vacation (two firsts: on an airplane…and out of the US). But the cross over to a high-carbon dioxide atmosphere has the greater long-term impact. I already suspect that unless something changes dramatically, climate change by midcentury will probably shorten my life.

Ailing U.S. pecan industry calls on India to reduce tariffs - UPI.com – I couldn’t find an update on this story from a few weeks ago. Evidently China used to buy 40% of the pecan crop in the US but now there is a tariff and the market is gone. So, the farmers are trying to develop the Indian market. It’s been tough to be a farmer for many years…but the tariffs have added even greater challenges.

Stressed out: Americans making themselves sick over politics: One in five report lost sleep, damaged friendships -- ScienceDaily – If individuals are stressed by politics….hopefully they’ll realize that it’s time to implement strategies to reduce the stress. Spending less time on ‘news’ would provide time to shift focus to other aspects of life – skew toward activities that make you happy and help others too. ‘Staying informed’ of politics 24/7 should not be a priority (although participating in elections should be).
