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.

Oyster Hatcheries Help the Industry Adapt to Climate Change – There are lots of aspects of climate change that impact oysters – making mitigation more complex. The industry is trying to be proactive as problems are recognized.

Could COVID-19 still be affecting us in decades to come? – A summary of some research particularly about brain function/Parkinsons and diabetes relationship with COVID-19 just beginning…there is so much we don’t know yet.

The porcupine’s winter in slow-motion – How do porcupines in Alaska survive being out and about in the winter?

Top 25 birds of the week: Bird Interactions – Mostly adults of the same species…but there are a few with different species and the first image is a pair of young owls (siblings).

2,000-Year-Old Roman Bowl Discovered Intact in the Netherlands – Blue glass that look like it could have been made very recently.

Locations of ancient Maya sacred groves of cacao trees discovered – History of cacao (chocolate) trees…grown around sinkholes…so special that the beans were used a currency.

Monarch butterfly numbers soar in California after dramatic losses – It’s great to have some good news about Monarchs….but they’re still a species that needs our help.

AccuWeather shares how an electric school bus fares in Alaska – Evidently the bus has done well even at -48 degrees Fahrenheit!

Musings from the parks: Navigating National, Wild, Recreational, and Scenic Rivers – Prompted by a proposal to refine limits on the horsepower boaters can use in Ozark Scenic Riverways in Missouri…a look at regulations at other rivers in the National Park System. I’d prefer that we begin the transition to electric motors (if motors are allowed at all) rather than only focusing on horsepower.

Epidemiologists develop advanced state-of-the-art tool for measuring the pace of aging – A blood test to measure the pace of biological aging…with the possibility of identifying interventions that would slow aging… and attempt to build aging health equity.

Birds through my Office Window - January 2022

/

There seemed to be a lot of bird activity visible from my office window this past month. The most common ones – juncos, sparrows (white-throated and house), finches (gold and house) - do not feature as much in my photos but they were always around.

Mourning Doves are too heavy for the feeder, but they are frequent visitors under the feeder on the deck and out in the yard. They also perch in the maple. They look largest when it is cold, and their feathers are fluffed.

The Northern Cardinals come to the feeders and flit all over the yard and trees. They seemed to be more activity in January than usual because there were more of them around. We have a resident pair that are around all year but in January there were at least 2 other pairs that were occasionally coming for food…and the interactions of both the males and females were high drama to watch.

The other resident pair that we usually see all during the year are a male and female (pictured) Red-bellied Woodpecker. Hopefully they’ll have young again this year. The birds dig through the seeds at the feeder…always leave with a peanut or sunflower seed.

There was a hawk that was around occasionally. Once it was at the edge of the forest diving into the leaves…came up empty. Another time I heard a tussle on the deck and glanced out to find the hawk on the deck railing – also without prey that it had probably been stalking. I was particularly relieved that it didn’t kill one of the birds coming to the feeder!

I’ve noticed Northern Flickers more in our yard. They blend into the leaves so well they are hard to spot…don’t come to the feeders.

The White-breasted Nuthatch comes to the feeder and is very assertive – drives away all except the Red-bellied Woodpecker.

There was a mixed flock of Red-winged Blackbirds and Brown-headed Cowbirds (pictured) that flew into the treetops of at the edge of the forest. I was glad they didn’t come down to our feeders! There were occasionally some cowbirds that came in the subsequent days; hope they don’t stick around for nesting season.

The downy woodpecker doesn’t come to our feeders frequently; they must be very hungry when the do because they eat quite a few seeds!

Zooming – January 2022

/

Not as many zoomed images to choose from in January – I did more photography with my phone than my bridge camera. I was in extra-rest mode for part of the month after my surgery and it was very cold outside. Still the usual January photo subjects have a showing this month: snow, birds, deer in our neighborhood and flowers indoors. Enjoy the January 2022 slide show!

Cancer Diary – Entry 11

/

The doctor that referred me for cancer surgery scheduled a follow up appointment for about 2.5 weeks after the surgery - assuming the surgeon would complete his role at about 2 weeks after the surgery (which I posted about in the 10th Cancer Diary post). The appointment with the doctor that will continue my care is the most recent milestone in my journey with cancer and getting treatment. He confirmed that I would not need radiation/chemo and ordered blood lab tests immediately and developed a plan for the next year: periodic blood tests and an ultrasound in a year. I am pleased that my cancer was caught early enough that I am on track to be ‘cured’ rather than living with cancer for the rest of my life.

It was bitterly cold the day of the appointment…but I was buoyed by the results I already knew from the surgeon and the continued fading of the hematoma/healing of the incision. The doctor provided excellent feedback and answered questions…the tech that did the blood draw did a great job getting the needle in smoothly then filling the multiple vials of blood required. On the way out of the building, I stopped for a few seconds to photograph the garden that looked so inviting when the weather was warmer; the fountain is turned off now and it’s too cold to linger but I still like the look of the place. I hurried to my car, thoroughly chilled, but appreciating the time out in the world, away from home. I celebrated that the appointment had been early enough that I got a close parking space!

I am so buoyed by the results that I am feeling more optimistic than I have all during the pandemic; I realize that, even though I was consciously reminding myself that the cancer had been detected early, I experienced a deep anxiety about it that became part of everything I was thinking and doing for the past few months.  Now I’ve started wearing earrings again (when I am not going to be taking a mask off and on), buying flowers every week at the grocery story and making multiple arrangements to place everywhere in the house. This is a time of celebration…a time to be happy that I am healthy and enjoying winter 2022.

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.

Photography In the National Parks: My 10 Favorite Shots From 2021 – I only went to one national park in 2021: New River Gorge (in West Virginia). There are so many beautiful National Parks to see…and they’re worth seeing again and again.

Big Gulp: Blue Catfish Eat Wood Duck – We’ve seen fishermen catch blue catfish at the base of Conowingo Dam (we’re there for the bald eagles). They are huge…sorry to learn that they eat ducks.

Top 25 birds of the week: Raptors! – How many of these live in your area of the world?

Air Pollution Makes It Harder for Bees to Sniff Out Flowers – Not just a problem for bees…also moths, hoverflies and butterflies are having a harder time. This results in a 14-31% reduction in pollination among plants exposed to polluted air.

Ocean microplastic pollution may be greater than estimated – Not a good trend…and this form of pollution that is new enough that the full impact is still being discovered.

With Fewer Animals to Move Their Seeds, Plants Are Stuck in Threatened Habitats – Another way the world is becoming less resilient at a time when climate change is pushing all life to use all the resilience available.

Large Permian Basin Methane Leaks Are Causing As Much Climate Pollution as 500,000 Cars – It’s frustrating that the oil industry has not been a better steward of resources they are extracting for energy. The methane leaks are a waste of the effort put into extraction….and bad for the planet too.

Dinosaur food and Hiroshima bomb survivors: maidenhair trees are ‘living fossils’ and your new favorite plant – Learn more about the ginkgo tree! There is one along my walking route in my neighborhood and others I find in local gardens and parks near where I live. They are so different from other trees…worth noticing.

North Sea Fossil Fuel Companies Plan to Invest More in Wind than Oil Drilling – Hurray! Maybe other companies around the world begin to do this too….a strategic move for Shell, Total and BP.

Antimicrobial resistance now a leading cause of death worldwide, study finds – This challenge will increase over time…if we don’t take action to slow the development of resistance and develop new antimicrobial techniques (maybe we need more strategies than simply trying to develop new antibiotics).

Bluebird Visit

/

Last week we had a small flock of Eastern Bluebirds visit out deck. It was a group of male and female birds…5 or 6 of them. They didn’t seem interested in the heated bird bath…just the feeder. They overwhelmed the house sparrows and house finches that are the regulars there. At one point there were 4 bluebirds at the feeder!

The males are more brightly colored that the females. It’s easy to see the difference in many of the pictures.

We don’t have regular visits from bluebirds…tend to see them occasionally in the winter. There are plenty of parks and conservation areas that have bluebird houses and provide habitat for them when they are raising young and away from our neighborhood. It feels good to contribute to the bluebirds well-being in winter with our feeder and heated bath.

Bluebirds have increased in numbers in our part of Maryland over the years that we have lived in the area with the participation of local governments and home owners with larger properties providing houses. A big concern now is the fall in insect populations; these birds need insects in their diet when they are breeding and then to feed their young.

Here are some bluebirds posts from previous years: January 2021, January 2020, February 2018, January 2018.

High Key Flowers

/

I’ve been buying flowers every time I go to the grocery story since the beginning of the year – so there were several different arrangements availablefor my indoor high key photo shoot. My set up was all in my home office…the plants on a small table or the window ledge…the bright sunlight on the other side of the window. The objective is arrange situations where like is coming behind the subject and to overexpose enough that the background goes to white. I sat in an office chair on the opposite side of the room – usually with the camera on my knee to keep it steady. The camera was far enough away from the flowers for the camera’s auto focus to perform well.

I experimented with composition…and focus. I like the textures and colors that seem to pop in the images because of the whiteness of the background and the lack of other clutter.

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.

The Roots of Violence – Reexamining bones excavated in the 1960s with new 3D imaging techniques….defining the violence of their lives and deaths shown in the bones. There is a history of archeological thinking here too. For a long time, evidently there was a presumption that prehistory was a less violent time…but the evidence is mounting that it was not.

Reducing air pollution: policies that pay off – An analysis done in Europe of the economic benefit of measures to reduce fine particle air pollution from wood heating and transport. It seems that similar type analysis could happen in other places in the world with some variation to tailor the reductions to have the biggest impact.

30 Incredible Winning Photos From the 2021 Nature Photographer of the Year Contest – Some eye-candy. My favorite is the caterpillar ‘walking among fennels’ – a similar scene happened at our CSA the first summer of the pandemic.

Assessing the U.S. Climate in 2021 – There were 20 separate billion-dollar weather and climate disasters that impacted the US in 2021.

Savanna Fire Management Can Fund Africa’s Protected Areas – Another article about the new economics we will need to understand to address climate change.

The forgotten medieval habit of 'two sleeps' – Maybe one long period of sleep is ‘modern’….that humans slept in two phases prior to the industrial revolution. One of my grandmothers developed a ‘two sleeps’ pattern late in her life when she was living alone….and I am beginning to wonder if I will.

The Horned Helmets Falsely Attributed to Vikings Are Actually Nearly 3,000 Years Old – Another look at artifacts…and better dating…and the history derived/assumed previously is changed.

Top 25 birds of the week: bird coloration! – This time of year…a little color from birds is a welcome sight. I’m noticing the ones in my neighborhood: Northern Cardinal, House finches, and red-bellied woodpeckers.

Across the Boreal Forest, Scientists Are Tracking Warming’s Toll – The northern forests becoming carbon emitters….. peatlands are drying out, and hotter, drier conditions are leading to a steady increase in wildfires — all of it accelerating permafrost thaw.

The Legacy Of "Pele's Grandson," Alex Lancaster – Some history of volcano observation on the big island.

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.

Top 25 Birds of the Week: January 2022 – This set includes a photo of a white-throated sparrow…one of the birds we see at our feeders only in the winter (along with juncos).

Threatened and Endangered Parks: Ghost Forests and rising seas – I recognized Blackwater National Wildlife Refuge in the pictures; I’ve visited it more frequently that any other NWR…and have observed some changes over the years. It was the first place I saw a bald eagle in the wild…back in 1990.

Musfur sinkhole: The chasm in Qatar’s desert. – Usually we think of the Arabian Peninsula being full of sand…but there are evidently sinkholes as well…deep enough to show layers of limestone and gypsum.

The Western megadrought is revealing America’s ‘lost national park’ – The water level in Lake Powell has fallen so much that Glen Canyon is revealed again. Gorgeous.

California mice eat Monarch butterflies – Mice eating butterflies that are on the ground had been observed in Mexico’s aggregation site…and now a similar interaction has been observed at a site in California where the Monarch’s aggregate.

Race and ethnicity across the nation – Data from the most recent census visualized on a map. Explore some places you know.

Findings open the way to more precise diagnoses and treatments of Alzheimer’s disease – A difference in Tau protein relates to slow or rapid development of the disease. There is a lot of research on the Alzheimer’s and other diseases that cause cognitive decline going on; with aging populations around globe, it is important to refine the way the diseases are diagnosed…and then treated. One treatment is not going to work for all.

Here's what you should keep in your car and other ways to prepare for winter driving – After the recent prolonged closure of I-95 in Virginia, I started thinking more about this…and will pack a few extra things in my car if I make a road trip to Texas this winter. I would normally have the items listed in the article anyway since I am minimizing the need to stop along the way during the pandemic (but I would need to check the batteries in the flashlight…and add some extras). I would add a sleeping bag too since it is relatively compact and would make it a lot easier to stay warm; I was surprised that this item was not on the list in the article. And I will not wait until the gas tank is down below ¼ tank before I stop for more!

See something weird at the bird feeder? It’s not just you – So far, the only somewhat unusual bird I’ve seen at our feeder was a red-breasted nuthatch; we see the white-breasted ones all the time but there was a season that we had a few of the red-breasted birds too.

See Pandas, Elephants, Cheetahs and More Enjoy a Snow Day at the National Zoo – Fun in the snow…the young panda seems to enjoy rolling or sliding down hills!

22 Months in COVID-19 Pandemic

/

22 months in COVID-19 pandemic is a long time to be in heightened awareness mode…long enough for new habits to become well established. I would feel very odd going into a store without a mask….or going shopping at a time where there are lots of people in the store…or shopping slowly…or going out to eat rather than getting takeout. These new habits are just part of the way I am out in the world right now; they are not difficult to sustain.

My concern about COVID-19 has increased over the past month as the Omicron variant has become more widespread and the infections/hospitalizations in Maryland (where I live) have increased dramatically. My husband and I have backed off the plans we had for beginning to get out more. We are enjoying our house and yard…doing outdoor activities on our own in areas without a lot of other people rather than meeting a group.

I take advantage of every opportunity to enjoy whatever I am doing:

…a sunrise before going into the grocery store

… the unfurling of yellow roses over several days as I do my normal activities in my home office (I had the vase on the window sill)

…the snow caught in the pinecones/greenery on our front door (I had opened the door to take it down to dismantle/take to the compost pile but decided to leave it)

Making the conscious effort to appreciate my surroundings is my best strategy for sustaining a positive attitude. I have also started setting 30 minute timers all during the day and doing 3 minutes of walking. It is a great way to move throughout the day and stay focused on whatever I need to do during the other 27 minutes!

My husband and I have planned what we will do after my cancer surgery since there will be a higher than usual chance we will be exposed to COVID-19. For him, being in the waiting room for hours is the challenge; even if he goes outside to eat/drink and everyone is masked when indoors…it will be a lot longer indoors away from home since the initial lockdowns of the pandemic. For me, the exposure could take place during the surgery itself…from the time I take off my mask to the time I wake up from anesthesia; presumably everyone will be masked and the air filtration will be good….but still more chance of exposure than my normal routine. Our plan for 5 days post-surgery is to be on separate floors of our house when we have our mask off (sleeping, eating/drinking, showering) ….and test if we have any symptoms. I’ll post more about it as we implement the pan.

By the time I am recovered from surgery and ready for another road trip to Texas, the Omicron variant may be waning and hopefully another variant is not burning bright and hot….but maybe that is wishful thinking.

Macro Photograph (Brookside Gardens) – Part II

/

Continuing the images from my walk around Brookside Gardens….

Even cold damaged flowers are good subjects for macro images…particularly with small water droplets on them. The amount of magnification makes quite a difference!

Juniper adds green and blue color to the scene this time of year.

I am always attracted to the horsetails near the visitor center…in a thick stand. These primitive plants have always fascinated me because they are a plant I learned about in a biology text book (way back in the early 1970s) then recognized in the wild on a day trip to Platt National Park.

And then there are the best of the rest. Do you recognize the gingko bud, a yellow holly berry, a rhododendron bud?

Overall – every time I go to Brookside there is something new to notice. My observational and photographic skills get a workout!

Macro Photograph (Brookside Gardens) – Part I

/

Kase Smartphone Macro Lens clipped to my phone and a Bluetooth remote shutter. Speed was not essential because it was too cold for insects, but I got a lot more images that he did!

While he was getting his equipment together, I looked at water droplets on nearby trees reflecting the forest.

The wood hydrangea had lots of surfaces of interest: dried flowers, leave scars, and buds for next season. Someday I want a wood hydrangea in my yard!

There was a vine growing on the wall of the visitor center with tiny tendrils ending in ‘suction cup’ like structures keeping the larger stem attached to the vertical surface.

Another stem with leaf scars and noticeable lenticles….and some bristles. I’m not sure what plant it was.

Finally – there were the camellias that are blooming this time of year: flowers and buds…lots of water droplets.

More Macro from Brookside tomorrow….

Neighborhood Walk in the Snow

/

I bundled up in snow pants, hiking boots, scarf, coat and gloves for a walk in our neighborhood after the snow had stopped; it was afternoon, but the temperature was still below freezing. My phone was on a lanyard and the Bluetooth clicker was in my hand….all set to take pictures along my route. Our driveway was still pristine when I walked through; we had opted not to shovel since we didn’t need to get out for a few days and it would melt before then. Our street had not been plowed yet, but cars had made tracks.

The evergreens were flocked with snow. I liked the way the long needles looked from underneath…more green showing. The cedars were heavy with snow, but I didn’t see any broken branches. There was a little breeze that would cause small amounts of snow to fall; the temperature and the wetness of the snow kept most of it in place.

There was a large tree that had many large branches starting a couple of feet above my height; the snow seemed to highlight their juncture. I wondered if the primary stem had been damaged when it was young.

The pond was surrounded by cattails holding snow. It appeared that erosion has reduced the size of the pond since it was dredged a few years ago.

I photographed a branch from a small tree from underneath. The branches were close enough together to hold a lot of snow….the cohesion of the crystals in this particular snow were impressive. A little breeze came through, but the snow stayed in place.

The fire hydrants in the neighborhood sported snow on every surface that was even a little horizontal. The roughness of tree bark also held snow.

When I got to the main road – I saw that the clouds were beginning to clear…great blue – yellow – orange color for the late afternoon.

I took one last picture before I turned back toward home. Someone had been out with a snowblower to clear sidewalks…preparing for the neighborhoods school children catching the bus the next day….or the day after.

There were some crepe myrtle pods from last fall holding mounds of snow. Two boys were making a small snowman nearby.

As I walked by the pond again, I noted that there were no sled tracks down the hill that my daughter thoroughly enjoyed 20 years ago. Have the neighborhood children not discovered it, or do they stick closer to their own yard and siblings because of the pandemic?  

Gleanings of the Week Ending January 8, 2022

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.

2021 Year In Review: Top Stories From The National Parks – Lots of perspectives in these ‘top stories’ – lots of challenges but some room for hope in 2022.

Earth in 2021 – A 3-minute video summary from NASA….lots of before and after catastrophic events. The text in the post has a short description of the events in the video.

Top 25 birds of the week: Birding! – Bird photographs…always a great look.

Stopping dementia at the nose with combination of rifampicin and resveratrol – The research was done in mice…they started preparation for human clinical trials in November. If it is effective in humans and can be produced/distributed economically, it could be a boon for aging populations around the world.

Saguaro National Park – A place I visited frequently while by daughter was in Tucson for graduate school. It’s interesting how they are monitoring the keystone species in the park…concern is that fewer young saguaros are surviving these days.

Climate-driven weather disasters inflicted billions in damage in 2021, study says – The cost of climate change already is impacting economies around the world….doing something to reduce/mitigate climate change is quickly becoming the option that makes the most economic sense for everyone.

Poison Ivy – You don’t want to touch it…but it’s best left alone when it’s growing in a place where people are unlikely to contact it. Its berries provide food for birds in the winter, it does not hurt the trees it climbs, and its leaves turn red in the fall.

Chalk steams: why ‘England’s rainforests’ are so rare and precious – This article brought back memories of wading in chalk bottomed creeks in the Dallas, TX area when I was teenager. I don’t remember much about the plants and animals…more about the fossils weathering out of the chalk.

2021 Year In Review - Another Year of Photography During The Pandemic – Beautiful places…and some little photography lessons too.

The year in chemistry: 2021’s biggest chemistry stories – 2021 was quite a year for big chemistry stories! Several of them are likely to have high impact for years to come.

First Snow this Winter

/

Our first snow of the season came this week…and it was about 6 inches that fell from the wee hours of the morning until about noon. The temperature hovered around 30 degrees.

I did little photography projects throughout the morning. The accumulation between 7:30 and 10 AM shows in the pictures below.

I stood in the open garage door to photograph the scene from the front of our house about sunrise while it was snowing heavily and leaned out to take a close picture of the holly growing at the corner of our house.

Later I went out on our covered/screened deck and opened the door to take pictures of the sycamore – old leaves, tangle of branches, and the snow clinging to the texture of the peeling bark.

The snow was sticking to near vertical surfaces of the deck.

I did some experimental pictures of the maple and a cedar through the screen (the screens were catching snow too). It made a counted cross stitch effect!

I heard a wren singing when I was in my office and looked for it…found it under the bench…and watching for a space at the feeder to open.

I also noticed some crows cleaning up around the base of the feeder out in the yard.

My husband too a picture of the deck. The feeder was periodically full of birds throughout the morning!

I made our traditional peppermint snow ice cream after most of the snow had fallen…skimming off the top layer of snow into a big bowl and then adding milk, pieces of peppermint candy, sugar, and vanilla. Mixed with my electric mixer. Yummy! I was not as successful at another traditional activity: photographing snowflakes. At first it was too warm and then it seemed like the flakes were all breaking on impact with my chilled plate. Maybe I’ll have better luck with the next snow.

Macro Photography (indoor)

/

I got a new macro lens for my phone over the holidays – a Kase Smartphone Macro Lens. It comes with wih a U-shaped clip which didn’t fit over the phone + case so I am using the clip that also came in the package. I leave the lens attached to the clip and store it in the small bag that was also included.  The advantage of this lens is the increased distance from the subject (i.e. I don’t have to get as close…a very good thing if the insect has a stinger!). It is a little heavier but, so far, it seems to be easier to hold the phone and lens steady…no tripod required.

My first experiments were indoors around the house. I started with flowers I’d bought recently. My favorite of this group is the yellow rose.

The acrylic yarn of my 40+ year old crocheted chair blanket shows how long lasting the fibers are! A macrame hanging my sister made is the same vintage. The material is twine-like and I wonder if she had to wear gloves while she was making it.

Some images printed on paper are pixelated when magnified…others are not.

Peacock feathers are like abstract art in macro view.

I looked at the way different surfaces with patterns appear in macro: pulp paper (Zentangle with Sharpie ink), plastic, an ivy ceramic coaster (I never noticed the yellow mark in the pattern before), a bamboo back scratcher handle…a joint of the stem, and a clear plastic ribbon with a gold pattern.

Two objects with inlay: a box and an earring. On the earring, the black piece that looks like the arms on a clock…is (unmagnified) a bird flying over a landscape.

And continuing with some other earring…small objects made large with magnification.

Zooming – December 2021

/

The usual birds and plants in the collection for December – plus some from the light display at Brookside Gardens. My camera’s zoom feature is one I use almost all the time to control what I want in the image….usually opting to make the subject fill most of the frame. Sometimes I want even more magnification and am forced to be content with the max my camera can do. All of the images this month were handheld except for the bald eagle; my camera was on a monopod for that one. Enjoy the show!

Cold Morning at Conowingo

/

The sun was just coming up when we were driving to the Conowingo Dam on the Susquehanna River…hoping to see bald eagles.

It was very cold, and we had winter gear to put on to put over our regular clothes when we got there: winter boots, snow pants, coats with hoods, scarves, gloves, handwarmers, footwarmers. It didn’t seem like there was much action when we got there but there were enough photographers that we thought there would likely be something to see. We bundled up. I put on my KF94 mask to keep my nose and lower part of my face warm. The temperature was in the mid-20s.

And then all we saw were gulls feeding in the churning water coming from the dam…too far away for good pictures. The black vultures were absent….first time we’ve been to Conowingo and not seen them. I put my camera on maximum zoom to scan the rocks and towers across the river; my husband was doing the same thing. No eagles.

I was just about to give up in frustration when I turned around and saw an eagle high in a tree on the hill behind me! There were branches in the way, but I managed to focus on the bird. The top of the head had a little brown. Maybe an early adult?

Then we spotted an eagle soaring and circling around us. Unfortunately, there was a vehicle leaving the secured parking lot and we couldn’t stand where we needed to photograph it in the air. But it was awesome to watch…and we saw where it landed in a tulip poplar tree with lots of seed pods.

While we were positioned to photograph the bird that had been soaring…we heard eagles nearby….realized the sound was not from the one we were photographing. We walked back so we could see the location where the first eagle had been perched. It was still there…and there was another eagle that was perched nearby! The sounds we heard must have been from from their interaction when the second eagle arrived!

The eagle on the right below is the one we saw first….the one on the left is the new arrival.

Overall – seeing 3 eagles – even if they were only in the trees – was awesome compared to the frustration of the first 15 minutes we were at Conowingo! Patience and looking around made the morning!

Gleanings of the Week Ending December 25, 2021

/

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.

New copper surface eliminates bacteria in just two minutes – One of the emerging technologies to fight bacteria (and viruses) without antibiotics. Copper is already being used in some applications, but this materials research developed a new structure of copper that is more effective and faster. The article didn’t comment about durability…but still very promising finding.

Home Battery Storage: The (Solar) Rich Get Richer – There is beginning to be more equity in solar panel installation….but storage is still a challenge at lower incomes. Some states have programs that may be the wave of the future and there are incentives in pending legislation. Hopefully a positive momentum will build over the next few years.

California Readies Launch of Largest Food Waste Recycling Program in the U.S. – Part of the county where I live in Maryland has curbside pickup of food waste for composting…but not the part where I live. I have a backyard compost bin…but many people do not so there is still considerable food waste going to the landfill.

10 Winter Birds to Spot During the Christmas Bird Count – Seen any of these in your area?

Why is snow white? – 3 videos…the last one with more ‘bonus’ explanations (such as why polar bears are white).

Top 25 birds of the week: Bird Pigment – This post was a bit confusing since it wasn’t explicit about which colors were from pigments ( as in the red of cardinals) and which were from light scattering caused by the physical structure of the feathers (for example, in blue jays). Read more about this non-pigment phenomenon particular for blue feathers here.

Winter is coming: Researchers uncover the surprising cause of the little ice age – New research shows that the little ice age in the early 1400s occurred when the Atlantic Meridional Overturning Circulation (AMOC) collapsed after a warming period which flushed Arctic ice into the north Atlantic, cooling it and reducing its saltiness. Could the AMOC collapse again with ice melting because of climate change? Existing climate models do not model the impacts of ice melt (making the north Atlantic cooler and less salty)!

From blood clots to infected neurons, how COVID threatens the brain – An overview of the research into how COVID-19 impacts the brain; there is still a lot more to be learned about this - probably one of the most devastating aspects of ‘long Covid’. It appears that the cognitive impact experienced by some COVID-19 survivors improves over time, but half the patients in one study were not back to normal after a year. It is a very sad prospect for individuals and for or society.

Watch This Giant Phantom Jellyfish With 33-Foot-Long Arms Float Through the Deep Ocean – The video is less than a minute…worth watching.

AAA Electric Vehicle Infographic — The Good & The Bad – My current car is a plug-in hybrid….the next one will most likely be an EV.

Old Faithful at Yellowstone (1880s-1909)

Internet Archive has 4 volumes of images of Yellowstone National Park produced by F. Jay Haynes from the 1880s to 1909. It is interesting to think about what it must have been like to visit the park during those early years. It would have taken a lot more effort to get there than it does today! At the same time – the facilities would have been minimal/primitive….there would not be crowds of people or problems with vandalism either.

I selected pictures of Old Faithful as sample images – a wonderful variety of depictions: 2 in color, 1 at sunrise. Each volume is well worth browsing for the other images as well.

Yellowstone National Park: in water colors (188?....the volume does not have a title or copyright page but presumably it was sometime after fall 1881 when he spent 2 months in the park and took over 200 photographs; he had a lease for a small photography studio in the park by 1884).

Yellowstone National Park: the world's wonderland (1889 with Truman Ward Ingersoll and Charles Frey)

Haynes souvenir album : Yellowstone Park (1909)

I’ve only been to Yellowstone once…and it was before I photography became a hobby…thinking about what time of year I want to go next time and hone my plans for the type of photography I want to attempt there.
