Readers’ wildlife photos

Why Evolution is True Feed - Thu, 04/24/2025 - 6:15am

Reader Mark Joseph recently sent in some bird photos from his friend Cliff’s April 2024 trip to Belize; part one was posted here, and this is part two.  I am not sure who wrote the captions, but they’re indented, and you can enlarge the photos by clicking on them.

Hooded oriole (Icterus cucullatus) – male:

Hooded warbler (Setophaga citrina) – male:

Least sandpiper (Calidris minutilla):

OK, this one is a bit of a story. Cliff called it a house wren, which is what I would have called it too, but when I went to look up the binomial to use in this post, I found out that the “house wren” has recently been split into *8* different species! So, this is now a Northern House Wren (Troglodytes aedon). Besides this common North American bird, the “Northern” group now has five area-specific Caribbean island species. There is also now a “Southern” group, the Southern House Wren and one erstwhile subspecies, Cobb’s Wren:

Limpkin (Aramus guarauna):

Prothonotary warbler (Protonotaria citrea):

Roadside hawk (Rupornis magnirostris):

Rose-throated becard (Pachyramphus aglaiae) – female, if I’m not mistaken:

Russet-naped wood rail (Aramides albiventris):

Rufous-tailed hummingbird (Amazilia tzacatl):

Vermilion flycatcher (Pyrocephalus obscurus) – male:

White-faced ibis (Plegadis chihi) – non-breeding plumage:

 

While looking through Cliff’s pictures of his trip to Belize, I see that he also did a nice series of six pictures of the Northern Jacana – Jacana spinosa (aka the Jesus bird, as it can walk on water); the comments with these pictures are Cliff’s:

Northern Jacana are very attractive birds that live pretty much on floating vegetation in freshwater marshes, ponds, etc:

They are very colorful in flight, squawking the entire time aloft.

These birds are interesting in that the female mates with several males, then the male raises the young (newborn Jacana can walk, swim, and feed themselves from birth):

 

Even the young birds have the famed Jacana ridiculously long toes for walking on floating vegetation:

 

This is one of my favorite images from the entire trip (so far)…

Making Waves or Just Noise? A Look at Shockwave Therapy

Science-based Medicine Feed - Thu, 04/24/2025 - 5:26am

I’ve been a runner—on and off—for over 25 years. For years, my goal was qualifying for the Boston Marathon. But I was never quite fast enough for my age group. At one point, I figured if I could just hold my best marathon time for another 20 years, I’d eventually “age into” a qualifying time. Unfortunately, my musculoskeletal system has other plans. […]

A Novel Concept for a Multiplanetary Crewed Mission to Mars and Ceres

Universe Today Feed - Wed, 04/23/2025 - 3:25pm

In a recent paper, a team of commercial space engineers proposed a Human-Crewed Interplanetary Transport Architecture (HUCITAR) to explore Mars and Ceres in a single journey. Their ambitious plan envisions six astronauts spending 4 years and seven months exploring these bodies, which could be ready to launch by 2035.

Seeing the Waves that Make the Sun's Corona So Hot

Universe Today Feed - Wed, 04/23/2025 - 3:09pm

If you happen to be enjoying a sunny day, thank the bright surface of the Sun, known as the photosphere. At a piping hot temperature of about 5,800 K, the photosphere provides nearly all the sunlight Earth receives. But for all its glorious radiance, the photosphere isn't the hottest part of the Sun. That award goes to the diffuse outer atmosphere of the Sun known as the corona, which has a temperature of more than a million Kelvin. Parts of the corona can be as hot as 20 million Kelvin, which is hotter than the Sun's core. Of course, the big mystery is why the corona is so hot.

Engineering a robot that can jump 10 feet high -- without legs

Matter and energy from Science Daily Feed - Wed, 04/23/2025 - 1:40pm
Inspired by the movements of a tiny parasitic worm, engineers have created a 5-inch soft robot that can jump as high as a basketball hoop. Their device, a silicone rod with a carbon-fiber spine, can leap 10 feet high even though it doesn't have legs. The researchers made it after watching high-speed video of nematodes pinching themselves into odd shapes to fling themselves forward and backward.

Scientists Ask For Help Classifying Galaxies From the Cosmic Noon

Universe Today Feed - Wed, 04/23/2025 - 12:45pm

Data from the James Webb Space Telescope (JWST) is coming in hot and heavy at this point, with various data streams from multiple instruments being reported in various papers. One exciting one will be released shortly in the Astrophysical Journal from researchers at the University of Kansas (KU), where researchers collected mid-infrared images of a part of the sky that holds galaxies from the time of the "cosmic noon" about 10 billion years ago. Their paper describes this survey and invites citizen scientists to help catalogue and classify some of their findings.
