Hagerman National Wildlife Refuge – March 2024

/

My March visit to Hagerman National Wildlife Refuge was on my way home the day after my mother’s funeral in Dallas. I needed the healing of being out in a natural place like Hagerman. There were the usual male red-wing blackbirds proclaiming spring and their territory. Several times I could see males spaced out over the landscape…a visible cue for the size of their territories.

There were American wigeon, gadwalls, northern pintails, and American coots on the water in small numbers. A neotropic cormorant was enjoying the warming sun on its wings. Some birds had probably already headed north.

There was a group of 2 great blue herons and a great egret in sentry mode. They must have already had their breakfast because they didn’t move while I was watching.

A vocal cardinal perched in a tree near the road.

I had two favorite birds of the morning: a killdeer that was posturing in a field just as started down the wildlife loop road (it looked like it was signaling something…but I don’t know what) and

A female common goldeneye…the first I had seen at Hagerman. This bird would certainly be moving north soon since most of their breeding area is in Canada and Alaska!

I continued home…glad that I had made the effort to photograph birds at Hagerman.

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.

Two Baby Condors at Pinnacles National Park Are Healthy, ‘Adorable Fluffballs’ – Avian flu killed at least 20 California Condors in Arizona and Utah last spring…so the health of these birds is great news. So far, their lead levels (often a problem if their parents bring them carrion with bullet fragments) are low. They will make their first flights in October or November.

Biden Designates Baaj Nwaavjo I'tah Kukveni - Ancestral Footprints of the Grand Canyon National Monument – Protecting the land around Grand Canyon National Park.

Nearly Two-Thirds of All Species Live in the Ground, Scientists Estimate - Soils are richer in life than coral reefs or rainforest canopies, providing a home to nearly two-thirds of all species. The study is the first to tally the total number of soil dwellers, large and small, finding that more than twice as many species live in the ground as was previously thought: 59 percent of all species depend on soil for their survival, including 90 percent of fungi, 86 percent of plants, and 40 percent of bacteria.

Incredible Winners of Light Microscopy Awards Show Artistry of Scientific Imaging – The beauty of microscopic life….

Research Sheds Light on Steamboat Geyser’s Eruptions, Past and Present – They discovered that the strength of shaking decreased as snow depth increased. The ability of snow to absorb sound makes a difference!

Stunning Fields of Sunflowers Are Blanketing North Dakota – The states farmers grew 625,000 acres of sunflowers this year…and they bloom throughout August. Maybe one year we’ll make the trek to see them; I haven’t been to North Dakota before.

Exceptional Winners of the 2023 Nature inFocus Photography Awards – Beautiful…and educational. My favorite image is the ant with aphids (“A Sappy Alliance”).

What Pots Say—and Don’t Say—About People – “What can such a well-traveled artifact tell us about the people who left it in the ground? Its culture of origin may be less important than how it fit into life where it was found.”

Microplastics found in human heart tissues, both before and after surgical procedures - Everywhere scientists look for microplastics, they've found them -- food, water, air and some parts of the human body….even in the heart. But it still is not known how/if the microplastics impact the cardiovascular system.

Microalgae vs. Mercury - In the search for ways to fight methylmercury in global waterways, scientists at Oak Ridge National Laboratory discovered that some forms of phytoplankton are good at degrading the potent neurotoxin.

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.

Why soil is a surprisingly noisy place – Wow! A whole new way of studying soil…listening to it.

Gas flares tied to premature deaths – A study done by Rice University environmental engineers with data from North Dakota and Texas. There are currently no limits to flaring, unfortunately. Why can’t we use the gas productively? It bothers me when we hear that we need more fossil fuels to observe the way the industry still is so wasteful and polluting.

Dying for makeup: Lead cosmetics poisoned 18th century European socialites in search of whiter skin – I had heard of lead makeup before…but never is this detail.

Top 25 birds of the week: forest birds – The only one of these that appears in the forest behind our house in Maryland is the Tufted Titmouse.

Study questions the role of vitamin D2 in human health but its sibling, vitamin D3, could be important for fighting infections – The labelling on foods fortified with Vitamin D does not say which type is used – hopefully it is D3. The supplemental Vitamin D I take is definitely D3.

The Prairie Ecologist – Photos of the Week – February 26, 2022 – Winter photography….it’s about over for us. Daffodils are up!

What is the best age to learn to read? – There is more variability that I realized…generally between 4 and 7. There is growing consensus that there is no reason to rush it. Learning language is key and often older children learn to read faster because their spoken language skills are greater.

Effects of noise on marine life – The study was focused on turtles and observed noise-induced hearing loss (sometimes temporarily) which hampers their ability to detect predators, communication, navigation, etc.

Rash-causing moths are spreading in Maine because of climate change – Browntail moths (native to Europe). I thought when I saw the headline that it might be about the saddleback caterpillar which is native to North America and has stinging spines that cause a painful rash. We had a specimen in the Brookside Gardens Wings of Fancy exhibit back in July/August 2018.

Study of algae in Acadia National Park lakes shows recovery from acidification – A success story…the Clean Air Act Amendments enacted in the 1900s are making a difference!

Dive beneath the pyramids of Egypt’s black pharaohs – The challenge of excavating a 2,300-year-old tomb that is submerged in rising groundwater.

Another Fire in Greenland – There have been more reports of fires in the far north this year. Evidently warm dry air causes Arctic circle landscapes (that are not ice and snow) to be very flammable…fires start and burn quite easily.

Top 25 Wild Bird Photographs of the Week: Pigeons and Doves – National Geographic – I was surprised at the diversity of these birds.

Call for green burial corridors alongside roads, railways and country footpaths -- ScienceDaily – I wonder how many other countries have a similar problem. Space for burials is probably already a challenge for almost all large cities.

How the sound in your office effects your mood – Aural architecture….how we listen to buildings, the sound within buildings, and how we react. It isn’t considered very often in the current built environment except for things like concert halls and sound proofing. Maybe in the future it will be. One segment of the article talked about the need for quite and nature sounds in city soundscapes…much better than sirens and traffic noise.

Air pollution speeds up aging of the lungs and increases chronic lung disease risk -- ScienceDaily – A large study…another reason to do everything we can to improve air quality.

Banding Hummingbirds – Banding larger birds has it’s challenges but a hummingbird….I’d never heard someone describe it. Kudos for the people that have the touch to do it well.

Engineers develop chip that converts wasted heat to usable energy -- ScienceDaily – Interesting idea…I wonder how long it will take to get this type of technology into laptops and solar panels?

How a Pokémon-like Card Game Is Changing the Way People Learn About the Environment – What a good idea. I hope more teachers start introducing their students to the Phylo game!

Solar panels cast shade on agriculture in a good way – Research from the University of Arizona…how solar panels could shade plants to help them survive in a hotter environment…and the plants help cool the air under the solar panels as they produce electricity! The plants that might do best are the leafy greens that tend to wilt in the mid-day heat. The leaves grow bigger in the shade too! Production of nutritious food and renewable energy in the same system.

'Upcycling' plastic bottles could give them a more useful second life -- ScienceDaily – Now that many countries that used to take our recycle waste have stopped accepting it, we are suddenly facing the problem of what to do with ‘recyclables’ closer to home. Making materials that have higher value is one way to keep more of it from ending up in landfills.

Soundscapes of Arizona’s Aravaipa Canyon – Cool Green Science – Listen to some nature audio…if it’s too cold to get outside and into the wild right now! These would make great backdrops to a meditation practice.

Image of the Day: Prickly Legs | The Scientist Magazine® - Froghoppers gain traction for jumping by piercing plant surfaces with their spiny legs! (Note: froghopper nymphs are spittlebugs!)

Photography in The National Parks: A Winter Shutdown Stay in Olympic National Park – I want to go! This is a national park I haven’t visited.

What kind of bug is a bug? | The Prairie Ecologist – A little entomology lesson.

Alaska in Flux: Slumping Coastlines – A comparison of a coastline between 1992 and 2018 …showing land slumping in to the Beaufort Sea. An airport is closer to the water now than in 1992.There is also a map showing that quite a bit of Alaska is wetter that is was in 1984. Lots of changes in the Alaska land.

Work Underway to Return the Shine to Thomas Jefferson Memorial – The Jefferson Memorial is probably my favorite in DC. I’m glad it’s getting the renovation it needs to look good into the future.

14 keys to a healthy diet | Berkeley Wellness – A little update based on most recent recommendations (for example, dietary cholesterol is not something to worry about since it has little effect on most people’s blood cholesterol).

Infographic: How Ginger Remodels the Microbiome | The Scientist Magazine® - I like ginger and am including it more consistently in my diet. It’s another food to boost gut health!
