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.

How the Groundbreaking Suez Canal Forever Transformed the World’s Shipping Routes – The official opening ceremony was on November 17, 1869. It had taken 10 years to build on the path of an ancient canal and was called “the greatest service to the commerce of the world since the discovery of America.” The project was funded mostly by Western Europe.

'Jekyll and Hyde' leaders do lasting damage - When supervisors swing between good and bad behavior, they do even more damage to their employees than ones that are abusive all the time. And there are some indications that this kind of leadership could be contagious, with a leader's volatility fostering volatility in others

Scientists find a 35,000-year-old saber-toothed kitten in the Siberian permafrost - The cat was just three weeks old when it died, but its cause of death is unknown. The kitten still had its whiskers and claws attached when it was pulled out of the permafrost, and was covered in a coat of short, thick, soft, dark brown fur. Its hair was about 20 to 30 millimeters long. When looking at the mummified cub, scientists found some interesting differences between the kitten and a modern lion cub, particularly, in their paws: the saber-toothed kitten had wider paws, but no carpal pads — that's the wrist joint that's help modern day felines absorb shock.

Hatchling Alligators at the Fort Worth Nature Center – The Dallas/Fort Worth area is at the edge of American Alligator range…but the Nature Center has confirmed that it has a breeding population there. The Fort Worth Nature Center is 3,650 acres of mixed habitat, owned and operated by the City of Forth Worth; it is one of the largest city-owned nature centers in the US. There is an alligator research project ongoing there now that the breeding population has been discovered.

Sitting too long can harm heart health, even for active people - 10 hours or more of sedentary behavior per day is associated with heightened risk of heart failure and cardiovascular death. I am so glad that I decided years ago to use a Swopper chair (without a back…bouncing) at my computer desk….so I am moving most of the time that I am there!

Bone marrow in the skull plays a surprisingly important role in ageing - Studies in mice and humans showed that ageing results in skull bone-marrow expanding, and in mice this marrow was more resistant to inflammation and other hallmarks of ageing.

Glaciers Reveal When Volcanoes Are on Brink of Eruption - New research shows that glaciers near active volcanoes flow faster than other glaciers. The findings suggest it would be possible to predict volcanic eruptions by tracking the speed of glaciers.

Can we live on our planet without destroying it? - With eight billion people, we currently use a lot of the Earth's resources in ways that are likely unsustainable. Research shows that humanity can stay within the planetary boundaries. But it seems that there is little political will to do so. A depressing commentary on humanity.

Memories are not only in the brain - In the future, we will need to treat our body more like the brain -- for example, consider what our pancreas remembers about the pattern of our past meals to maintain healthy levels of blood glucose or consider what a cancer cell remembers about the pattern of chemotherapy.

Astronauts of the underworld: The scientists venturing into the deep, dark Earth - Hundreds of cave entrances are known on Earth, the Moon, even Mars. Many have never been explored.

Zooming – March 2024

/

Lots of birds in the Zooming slide show this month – from the Whooping Crane Festival in south Texas as well as Josey Ranch (Carrollton TX), the Springfield Botanical Gardens (Springfield MO) and Hagerman National Wildlife Refuge (near Sherman TX). I find myself picking images that show bird behavior rather than portraits.

There are spring flowers in this collection as well…more of those coming in April!

Enjoy the March 2024 slide show!

Leonabelle Turnbull Birding Center

/

We signed up for a shorebird identification field trip for the third afternoon of the Whooping Crane Festival. We got on the bus after lunch and, it turned out, spent the whole session at Leonabelle Turnbull Birding Center…which was fine with us since we had wanted to return there. We spent less time with the guide and just enjoyed all the birds at the place. There is a lot to see; the boardwalk makes it easy to see birds without disturbing them. The shallows are a popular place for them to feel secure enough to rest and bathe…and snack.

American white pelicans – in a big group or singles.

The common gallinule was near the alligator (again). I decided to take close up views of the feet (very long toes).

A black necked stilt wondered along through other species…looking aloof.

The green-winged teals were bathing…preening.

Grackles were bathing and preening too….or making raucous noise in the reeds and glaring at my camera.

A pied-billed grebe wandered near the reeds…hiding in plain sight as usual. Once I noticed the bird, I took a series of pictures as it found lunch.

A northern shoveler snoozed…another perched on a post in the water.

Ibis preened and stretched their wings.

I took a series of images of a bird in the shallows…thoroughly cleaning its feathers. It takes a series of contortions. The bird appeared to be enjoying the water!

A blue-winged teal showed the blue on its wing when it bathed.

Now for some group pictures. They are good for size comparison and ID practice. The first has 2 black-necked stilts and a male northern shoveler.

The second had a black-necked stilt and 4 American avocets.

The smaller birds were easily startled and would explode up into air…circle and return very close to where they were before the panic.

There were neotropic cormorants seemingly content to just sit in the sun.

There was a tricolored heron that seemed to be posing for pictures. I couldn’t resist!

The alligator did not move at all in the several hours we were there!

Overall – the place lived up to my expectations; we could have done it on our own rather than with the bus/guide. I am beginning to understand better that we have learned enough about birding to leave more free time to during festivals…or go early/stay late.

The last field trip of the festival would be the next morning at Fennessey Ranch.

King Ranch

/

The second day of the Whooping Crane Festival started early; we got on a bus to head to the King Ranch at 6 AM! The King Ranch Visitor Center was a little over an hour from Port Aransas (and we did not take the ferry). By the time we got there the sun was up.

We had a ‘rest stop’ at the visitor center…plenty of time to look around for birds. There were curve-billed thrashers on some prickly pear cactus.

A rufous hummingbird was not bothered by the sudden influx of people. It stayed in place long enough for everyone to get a good look.

Mockingbirds were around too….they are the state bird of Texas.

A golden-fronted woodpecker was spotted. It moved around a lot but there always seemed to be twigs between me and the bird!

Then we did most of our viewing from the bus for a bit since the ranch is so big…and the trip has a limited amount of time. I managed some OK pictures through the windows: a roadrunner and crested caracara….

Longhorn cattle.

We made a stop and saw a group of sandhill cranes in the distance.

Back on the bus…we had been seeing American kestrels all  morning and I eventually managed to get an image of one through the bus window…good enough for id but focus not sharp enough.

A group of female wild turkeys moved away as our bus got closer. Later we would see a group of male turkeys.

Another raptor through the bus window…a red-shouldered hawk.

The bus stopped at a water impoundment…and we all got an excellent view of an American Bittern.

There was a feeding station for birds at the next stop. We got good looks at red-winged blackbirds and gold-fronted woodpeckers…

And green jays!

There was a least grebe in the water a little ways down the road.

A snowy egret had caught breakfast.

Green-winged teal, pyrrhuloxia, and American Coots were also enjoying the water.

Alligator!

A Great Egret took off as the alligator headed toward it.

In the distance….Cinnamon teal with blue winged teal and a black necked stilt.

A great kiskadee made an appearance.

A black-crowned night heron is often hard to see in heavy vegetation. I always feel lucky when I finally see it and luckier still to get a photograph.

And the male turkeys were the last birds we saw as we headed back to the visitor center.

My husband and I both enjoyed this field trip…saw a lot of birds that we didn’t see during any of other field trips. It was interesting to learn a little history of the King Ranch as well. We had enough time for a quick lunch before showing up for trip out on a boat in the afternoon.

Road Trip to the Texas Gulf Coast

/

We had registered for the Whooping Crane Festival months ago…and managed to attend it between my mother’s death and her funeral. Being out in nature at a birding festival was a healing activity. It helped that my husband did all the driving. We made the drive from our home in Missouri to Port Aransas TX over 2 days. We started out before sunrise…

The clouds gradually dissipated into whisps before the sky cleared entirely.

I enjoyed trying to take pictures as we went through Dallas…not something I get to do very often because I am usually driving.

We stopped near Austin for the night. We got to Port Aransas early enough for lunch and to visit Roberts Point Park. There were groups of brown pelicans and cormorants easily viewed from the park.  I liked the pelicans at rest…images in high key.

There was a snowy egret on the rocks showing off his yellow socks. When I looked at my pictures on my larger monitor, I noticed that there are yellow strips on the back of the legs!

There were large ships visible in the channel.

We also visited the Leonabelle Turnbull Birding Center…quickly realizing that we’d have to return when we had more time.

There were black-necked stilts – with their striking black and white bodies, straight black bill, and pink legs.

Blue winged teals flashing iridescent color as they preened.

A very sedentary alligator was lolling below the  boardwalk (although with its eye open).

A common gallinule was feeding nearby.

A group of American white pelicans were preening in the shallows.

A larger group was on the shore.

Green winged teals preening in the shallow water…or lazing on the shore.

White ibis were in the area…sometimes feeding together and sometimes in small groups.

We were there in the early afternoon, and it surprised me that the light made the water color and shadows so artsy for this grouping for birds – snoozing and preening. At this moment they must have all felt very secure.

Just before we left, I tried to get a picture of the whooping cranes that were feeding in the distance  – an adult and colt (with brownish feathers on the head and parts of the body). These are the birds we came to the area to see. All the other birds are a big bonus!

We headed for our first field trip…a Mustang Island boat tour (the topic of tomorrow’s post).

Gleanings of the Week Ending December 16, 2023

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 World’s Oldest Living Land Animal, a Tortoise Named Jonathan, Turns 191 – He lives on St. Helena (the small island in the Atlantic where Napoleon Bonaparte died). He has lost his sense of smell and is virtually blind from cataracts, but his appetite is good!

Extreme Weather Inflicting Higher Costs but Fewer Deaths – Improved warning systems have been key to reducing the loss of life from cyclones, floods, and fires. Kudos to the governments that have implemented them. Hopefully Africa will be able to increase their weather stations and early warning systems…catch up with other parts of the world.

25 Incredible Photos in the Running for Wildlife Photographer of the Year People’s Choice Award – Which one is your favorite? Mine is the ‘happy turtle’ with the dragonfly on his nose.

Here’s What Can Cause Itchiness – Interesting….Staphylococcus aureus could the culprit for some people with eczema….maybe resulting in effective treatment/relief.

Nēnē: The Recovery of the Hawaiian Goose - Today, there are some 3,200 nēnē in the wild. By almost any measure, it’s a stunning conservation success. The threats of habitat fragmentation and invasive predators are omnipresent, so the birds need constant attention from conservationists and wildlife managers. Currently, there are populations on Hawai’i, Kaua’i, Maui and Molokai.

Secrets of the Catacombs - A subterranean necropolis offers archaeologists a rare glimpse of Rome’s early Jewish community. More than 60 catacombs, amounting to hundreds of miles of passages, have been identified beneath the Rome; they were the common approach to burial from the second through fifth century AD. Villa Torlonia, discovered in 1919, was the sixth, and so far the last, Jewish catacomb to be found in Rome and is one of just two accessible today. The catacomb’s passageways are lined with nearly 4,000 shelves carved into the walls to hold the dead. Many of the names of the deceased are still visible, generally painted on or carved into stucco used to seal the graves, along with blessings to rest in peace and other inscriptions. In a few places, the catacomb’s narrow passageways open into atriums where colorful frescoes decorate the vaulted ceilings and many of the arched recesses. In addition to menorahs, these frescoes feature Jewish motifs such as a holy ark to house Torah scrolls; shofars, ram’s-horn trumpets blown on religious holidays; and lulavs, palm branches waved during the festival of Sukkot, which celebrates the harvest season. There are also geometric designs and illustrations of peacocks, roosters, flowers, and fruit trees, possibly meant to depict paradise.

Wild Kiwis Born Near New Zealand’s Capital for the First Time in More Than 150 Years – Another bird conservation success in this week’s gleanings!

New Thoughts on Neanderthal Hunters - Neanderthals may have gathered in large groups to hunt and consume an elephant, and they may also have been able to preserve and store such a large amount of food.

Rare, White Alligator Born at Florida Wildlife Park - The leucistic reptile was born at Gatorland, a 110-acre park located south of downtown Orlando. The new gators are descendants of a group of leucistic alligators found in a Louisiana swamp in 1987. Since 2008, three of those Louisiana gators have been living at Gatorland.

500 year old hand grenades (China) – 59 spherical projectiles discovered in a storeroom along the Great Wall near the popular Badaling section. They were made of stone and had been drilled with holes that could be filled with gunpowder and sealed, creating an explosive effect when hurled at an enemy.
