Gleanings of the Week Ending November 30, 2024

/

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.

Bird Photography Boat Tour

/

Our second day of the Whooping Crane Festival continued with another boat tour after returning from the King Ranch and a quick lunch. The afternoon emphasis was on bird photography. The difference was subtle. The guide did suggest some settings to accommodate photographing in the very bright environment of a sunny day. I opted to take the normal opportunities to photograph birds as usual…but then took some photographic challenges too.

I started before we even boarded the boat. Grackles were taking snack packaging out of a trash can. The female seemed to be unimpressed with her partner’s antics.

I attempted to get a double-crested cormorant taking off from the water…managed to capture the form and splashes of water but the eye doesn’t show….plenty of room for improvement.

There were terns (probably common terns) diving toward the water for fish. I tried pointing my camera in that direction and pressing the button to take multiple pictures in fast succession. It was hard to hold the camera still as the boat moved! The shape of the bird as it nears the surface of the water was something I couldn’t study until I looked at my pictures on a bigger screen. This was my first attempt at photographing feeding terns!

The back of a white-tailed hawk – the only sighting of this species of the trip. It isn’t a great picture in the traditional sense….but it does tell a story. The bird was sitting in dead mangroves; the mangroves died during very cold weather a few years ago and recovery is slow; hurricane damage to the Aransas area would be even worse than before if one comes through before the mangroves can become established again.

The birds always seemed to be a little further away than optimal…and the boat was rocking. But I took pictures anyway: white ibis, little blue heron, osprey, great egret, and great blue heron. I tend to take photographs rather than make notes about what I am seeing…it’s easier with the camera already in hand!

And then there were the reddish egrets… with their pink and black bill.

And finally one started foraging…moving rapidly in the shallows. It seemed to veer off suddenly…something there that the bird didn’t expect?

I took group pictures of birds on small islands in the water…always interesting to see how many I can identify on my big screen later. In the one below, I see brown pelicans (adult and juvenile), American white pelicans, cormorants (double crested probably)…all in the foreground.

As I zoomed in on birds that were not in a group I noticed a black skimmer and some Caspian terns.

It’s always a thrill to see a bird I would not have seen without being on a birding field trip like this red-breast merganser. It was a single bird…swimming rapidly away from the boat…and I probably would not have noticed it without someone pointing it out. I’m not sure it was the guide or another participant that noticed it.

The same was true for another black-crowned night heron.  I photographed one on the King Ranch in the morning! I was pleased that I was able to find and focus on the bird more easily than many of the others on the boat.

The light began to change as we neared the end of the day. There were enough clouds to try a non-bird landscape shot of the water the sky…a bit of land at the horizon.

I changed a setting on my camera to try an artsy image of a cormorant and the shore as we came back toward the dock.

And then the boat stopped just before we got to the dock….for dolphins. I couldn’t top my husband’s dolphin picture in the bow wave of the big ship, but it was fun trying to anticipate when they would surface!

And then one last picture before we got off the boat! It was a great second day at the Whooping Crane Festival. The next morning was an early one….getting on a boat at 6 AM to see Whooping Cranes in the Aransas National Wild Life Refuge. We headed to the hotel for an early evening to be ready for it.

Zooming – November 2023

/

November 2023 was a month of contrasts…an increase in day trips (to the Springfield Botanical Garden and Butterfly Palace in Branson) and then the more confined views while a parent was in the hospital/recovering at home. Photography is something I enjoy in almost every circumstance. I am either trying to capture a moment or create an artistic composition. And the zoom feature on my cameras are almost always used!

Carrollton Yard – September 2023

/

There were no 100-degree days during the visit to my parents in Carrollton TX in late September; the yard was recovering – coping much better with the highs in the 90s. The sprinklers were able to make up for the lack of rain. The orange spider lilies were beginning to bloom. They were part of the landscaping in my sister’s house purchased over 30 years ago; she has propagated them into several other family yards. The red yuccas are still making seed pods, but the ratio has shifted to mature (and open) pods; those plants were the start of red yuccas in other yards as well.

We cut some of the spider lilies to enjoy inside. I did some high key photography of them – the vase in a window to create the bright background behind the flowers.

Hagerman National Wildlife Refuge – September 2023 (2)

/

I saw more than birds at Hagerman in September. There were large numbers of dragonflies in the air. I managed to see one sitting on a bit of dried grass near the road; photographed it through my open car window (like I do almost everything along the road through the refuge). There seemed to be so many dragonflies; it’s a good sign that there is a healthy population at Hagerman; they’ll lay eggs in the ponds where the larvae will overwinter – food for fish.

I did get out to photograph a large piece of driftwood that was on an island in the deepest pond. I liked the curves and the mystery of how it ended up positioned the way it was. Were their branches buried in the silt that kept it from falling over?

Back at the butterfly garden, I photographed three types of butterflies. I had seen all of them on previous visits.

The Monarchs were more numerous this time and I realized that they were probably migrating south to Mexico for the winter.  Supposedly the ones that make the long journey are larger than the ones that live their whole life during the summer months – never making a migration. Will there still be Monarch’s coming through when I return at the end of October? Maybe. The first frost in the Hagerman area is usually not before mid-November.

There was a bumblebee enjoying the flowers. I tried to photograph it from different angles.

Road trip to/from Carrollton TX

/

I made my monthly trip to Carrollton in the last week of September. It was very hot on the drive down. When I stopped at the Texas Welcome Center after crossing the Red River from Oklahoma it was already in the 90s. I had been listening to a wider variety of music during the drive down – relying on other sources than my usual USB stick; it kept me more alert during the drive.

The usual check of the beautyberry at the welcome center revealed that the berries are almost all turned purple. I also realized that there seemed to be a lot more plants than last year. Hurray for the beautyberry surviving and thriving the extra hot days this past summer!

The trip home started a week later – a little before 6 AM. The color before sunrise dominated the horizon as I made my first stop about 7 at a truck stop north of Denison TX.

The completion of asphalt work on several stretches of my route through Oklahoma made the drive the smoothest I can remember….and my husband had barbeque ready when I got home. As usual – it was good to be home again.

Zooming – September 2023

/

The beauty of the early morning in Texas - Hagerman and Josey Ranch and my parents’ yard….the wildness of Shaw Nature Reserve (near St. Louis MO) in the early afternoon…the joys of nature in my neighborhood (Nixa MO). These are the locations where my selections of zoomed images for September were made. The month was very much between summer and fall – starting hot and getting a bit cooler as the month progressed, still very green but the occasional beginning of fall color. Enjoy the September slideshow!

Hagerman National Wildlife Refuge – July 2023 (2)

/

The butterfly garden at Hagerman National Wildlife Refuge had butterflies in July. There were Queen butterflies feeding in a group – the longer one looked, the more butterflies there seemed to be! This butterfly is seen more frequently further south than north Texas (almost into Oklahoma); maybe the extremely hot summer is pushing them further north.

The other butterfly I photographed was a male black swallowtail – a large butterfly that flutters as it collects nectar (as seen in the video below).

There were grasshoppers too! I photographed two after I startled them on the path and saw where they landed on a plant (and managed to zoom in with my camera to photograph them without being close enough to force them to move again).

It didn’t take long in the butterfly garden before I needed water…and air conditioning! I continued my road trip to Carrollton.

Josey Ranch Pocket Prairie – June 2023

/

My original plan was to walk around the Pocket Prairie and take macro pictures with my phone. It was a good thing my bridge camera (Canon Powershot SX70 HS) since the morning was very breezy…too much for getting close shots with the phone. The optical zoom on the bridge camera was the only option.

The trash cans near the picnic table are Carrollton themed! Are they new this season? I don’t remember them from before.

The prairie area is full of May flowers setting seed and then the full summer flowers in bloom. I particularly enjoy the sunflowers (buds and flowers).

Across the pond from the Pocket Prairie – a Great Egret was looking for breakfast.

Maybe the morning I go in July will be less breezy and the macro plan will work….and there might be more insects too!

Josey Ranch – March 2023

/

I went to Josey Ranch (Carrollton, TX) in the early morning. The male grackles were posturing. The females seemed to be mostly ignoring them.

There were two Great Egrets in breeding plumage staying together as they looked for breakfast.

There seemed to be more cormorants than usual. They are probably moving northward since their breeding grounds are in the norther part of the US and into Canada.

There were a few scaups and ruddy ducks left. They too are moving northward. I don’t expect to see them in April.

I walked to the garden area between the water and the two buildings. The trees are beginning to leaf out and roses are blooming. The area was impacted by the harsher (hotter and drier) summer and it will be interesting to observe how many of the plants will regain their vigor in the upcoming months.

March is a transition month. It will be interesting to see if more of the summer birds show up when I visit in April. I always check the pond (or is it a lake?); it’s an short, easy outing and their always seems to be something new to observe.
