Gleanings of the Week Ending May 31, 2025

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.

10 Ways Vincent Van Gogh Continues to Make News, Even Today – An artist that has been ‘newsworthy’ for a very long time. This post about recent instances of ‘Van Gogh mania.’

Measles vaccines save millions of lives each year – Statistics about measles and the impact of the vaccine…history and how the choices we make will have impacts on the future trajectory of the disease.

New River Gorge National Park and Preserve – It became a national park in 2020. I’ve driven through it…stopped at a visitor center…but haven’t experienced it the way I have other national parks.

Forty Years of Change in Louisiana’s Wetlands – Images from Landsat 9 from 1985 and 2024 show that much of the wetland has transitioned to open water….reshaped by storms and sea level rise.

In healthy aging, carb quality counts - The researchers analyzed data from Nurses' Health Study questionnaires collected every four years between 1984 and 2016 to examine the midlife diets and eventual health outcomes of more than 47,000 women who were between the ages of 70 and 93 in 2016. The analysis showed intakes of total carbohydrates, high-quality carbohydrates from whole grains, fruits, vegetables, and legumes, and total dietary fiber in midlife were linked to 6 to 37% greater likelihood of healthy aging and several areas of positive mental and physical health.

Wildlife Photographer Captures Mid-Air Battle of Two Birds Fighting for Dinner – The battle over a vole between a Northern Harrier and Short-eared Owl in British Columbia, Canada. Dramatic photos. Both birds are over Missouri Prairies in the winter too!

How the humble chestnut traced the rise and fall of the Roman Empire - According to researchers in Switzerland, the Romans had something of a penchant for sweet chestnut trees, spreading them across Europe. But it wasn't so much the delicate, earthy chestnuts they craved – instead, it was the fast-regrowing timber they prized most, as raw material for their empire's expansion. And this led to them exporting tree cultivation techniques such as coppicing too, which have helped the chestnut flourish across the continent.

China’s Mega Dam Project Poses Big Risks for Asia’s Grand Canyon - China’s plans to build a massive hydro project in Tibet have sparked fears about the environmental impacts on the world’s longest and deepest canyon. It has also alarmed neighboring India, which fears that China could hold back or even weaponize river water it depends on.

Step Into a Painstakingly Recreated 3D Model of the Parthenon, Now Restored to Its Ancient Glory - By combining archaeology and technology, a researcher has shed light on a longstanding architectural mystery: how the ancient Greeks experienced the inside of the Parthenon, the Athenian Acropolis’ largest temple, built and dedicated to the goddess Athena in the fifth century B.C.E.

How Tikal Became One of the Greatest Mayan Cities—and Then Vanished - Nowadays, the ruins of Tikal, an ancient Maya city in northern Guatemala, have been largely reclaimed by the jungle. Howler monkeys jump from pyramid to pyramid. Bats hide in the crevices of abandoned homes. Bullet ants and tarantulas crawl along the forest floor while coatis—racoon-like animals with long, upright tails—search for fallen fruit. Many of the city’s structures remain unexcavated to ensure their preservation. Tikal began life as a series of small, unassuming hamlets. Across centuries, it grew into one of the largest and mightiest cities in the loosely affiliated network of municipalities that made up the Maya civilization. At its peak, which approximately lasted from 600 to 900 C.E., Tikal comprised an area of roughly 50 square miles, 3,000 stone structures, and a population that may at one point have exceeded 60,000 people. While other Maya settlements like Chichen Itza remained inhabited well into the 12th century C.E., Tikal is thought to have collapsed around the year 900.

Hagerman National Wildlife Refuge – December 2022

Back in November, I stopped at Hagerman National Wildlife Refuge on my way down to Carrollton, TX. It is just outside Sherman, TX…a little over an hour away from my destination. The refuge was active in the early afternoon…with some migrants still around (link to November post).

In December, I opted to do a quick drive through on my way home so it was in the morning about an hour after sunrise; it was not a great time for seeing large numbers of birds. It was too late to see birds that had roosted in the ponds…and it was too cold and windy to linger very long with the windows open (I was using my car as a mobile blind).

I enjoyed seeing a flock of male red-winged blackbirds in stubble near the road….rise up as a group then coming back down like a wave crashing on beach to feed again…repeat. Their red and yellow markings were flashing every time they started up out of the dried vegetation and when they landed again.

A heron stood in the shallows with its feathers ruffled by the wind. The day was still new enough for the water to be morning blue.

I also saw a Harrier Hawk – hunting…circling over the stubble and water’s edge. I didn’t get a picture, unfortunately, but I spent a few minutes watching the awesome grace of the bird dealing with the wind and looking for breakfast.

The clouds began to cover the sun periodically and I took some refuge landscape shots – complete with oil pump jacks (it is Texas).

The pintails, mallards, and shovelers were around….enjoying the bounty of the refuge.

Gulls were mostly staying put in the shallows.

My plan is to stop at the refuge as I continue to make monthly treks to Carrollton…see the changes at the refuge as the winter progresses….and then the spring migration and flowers.

Festival of the Cranes – part 8

After the fly out, we headed to the Bosque del Apache National Wildlife Refuge visitor center to meet the bus for a Raptor ID tour.

The refuge is home to many red-tailed hawks…several different morphs. The basic ‘football’ shape is what we were looking for in the trees.

The bald eagle was in the snag in the middle of the flight deck pond. Nothing happened when the eagle opened its wings and moved all little (just as I snapped a picture…good enough to identify it as a bald eagle but not much else).

Later the bird suddenly flew away….and caused a cloud of snow geese to rise all at one time from the water’s surface.

There are a lot of northern harriers this year too. Every time we drove the wildlife loop, we saw a few. They fly low over the fields looking for their prey.

There were other birds that were not raptors that we saw too. The ravens seemed to pose of us.

My favorite birds to watch were the hooded mergansers. At first there was just one pair interacting…then another male came along and then another female. They were almost beyond the range of my camera without the monopod. The first pair was acting a lot like is was time to breed but New Mexico is far from their breeding grounds.

The tour was an enjoyable 3 hours around the refuge wildlife loop.

Laguna Atascosa National Wildlife Refuge

Our third day at the Rio Grande Valley Birding Festival did not start out well: our bus has a mechanical problem and our departure was delayed by about 3 hours. Fortunately, the replan included a lengthening of the trip by three hours and provisions (picnic lunch). On the plus side – we avoided some rain showers that moved through while we were waiting; on the negative side – we could have slept later (getting up at 4 AM is common at birding festivals!).  Our destination was the Laguna Atascosa National Wildlife Refuge. We didn’t seen any ocelots that the refuge is trying to protect…but we did see plenty of birds. The days was very cloudy and misty – not good for photographing. I picked a few that were good enjoy enough for identification.

There were snow geese coming and going. I liked this line because of the different morphs visible.

There was a Little Blue Heron fishing in the shallows

And a Great Blue Heron standing on one leg surveying the shore.

A group of Forster’s terns, with the black feathers around and back from their eyes) were grouped along the shore (looks like the birds behind them were snoozing).

2017 11 IMG_5690.jpg

The Forster’s tern is in the middle of this image. The largest bird is a Caspian Tern and the one in front is a Royal Tern. The Royal Terns I’d seen in Maryland always looked like they were wearing a black cap but that is only during the breeding season…not this time of year in South Texas.

A brown pelican flew above – following the shoreline.

White Ibis wandered through the other shore birds.

The Crested Caracara were new to me. Since the ones I saw on the field trip were a little far away – I took a picture of a captive bird as the Expo.

I took a close up of a prickly pear tuna (fruit)…note the spines.

Side by side – a Lesser and Greater Yellowlegs.

We were all on the bus when a male Northern Harrier swooped down into the field beside the road and hovered over prey. I did pretty well taking this series through the bus window since there was no time to do anything better.

There is a platform where aplomado falcons are nesting. This is an exciting recovery story since this bird was gone from the area for years and has only recently been reintroduced and is breeding again in south Texas. I took a picture of the captive falcon at the Expo just as I had the Crested Caracara.

We stopped at the visitor’s center and walked around the cards there. Red-winged blackbirds are all over North America!

The white winged doves are summer birds in south Texas according to allaboutbirds but there were still a lot of them around in mid-November; I wonder if they are really year round in the Rio Grande Valley.

 It was a longer day that we’d anticipated but better than we thought might happen in the hour or so after we initially learned of the bus problem. In the end we decided that the Laguna Atascosa trip was well worth it.
