The remarkable pelican eel

This video, embedded in a report posted by Science, shows the remarkable behavior of the pelican eel (Eurypharynx pelecanoides), also called the “gulper eel” for reasons that will become obvious.  This rarely-seen creature, the only species in the family Eurypharyngidae, has now been put on video for the first time. While Wikipedia says this, The stomach […]

Readers’ wildlife photos

Send in your good nature photos, please! Today we have some nice photos from Idaho taken by Stephen Barnard; I’ve indented his commentary: A rainbow trout (Oncorhynchus mykiss) taking an unidentified insect. A mahogany dun mayfly— last mayfly to hatch here in the fall. Common named: could be any of several species and even genera. Great horned […]

Stephen Barnard has returned with some lovely photos from his ranch in Idaho. His captions are indented: First, a Rainbow Trout (the eye, Oncorhynchus mykiss) about to eat a Callibaetis mayfly, taken a few days ago. The mayfly is in the act of laying eggs, clearly seen in the photo. Callibaetis mayflies have the notable property that […]

Male pipefish who get pregnant reduce investment in their offspring if they see a sexy female

This new paper in the Proceedings of the Royal Society B caught my eye because of its title (abstract here but paper behind a paywall; judicious inquiry might yield you a pdf).  Check out the title and the abstract, and I’ll explain a bit of the results below (I read the paper quickly): First, a […]

Readers’ wildlife photos

Stephen Barnard from Idaho has sent some diverse photos, including an unusual montage. His notes are indented. Boris (the male American kestral [Falco sparverius] who bred in Stephen’s nestbox): A female fledgling: There are at least three kestrel fledglings, and probably at least four. I think that’s Natasha [the mother] up high and the other four […]

Readers’ wildlife photos (and a video)

Stephen Barnard has sent us a batch of lovely photos from Idaho. Among his many great pictures, this first one, of the female American kestrel (Falco sparverius) roosting in Stephen’s nestbox, has to be one of my favorites: Stephen sent some technical info: Natasha. This photo is with my Canon 5D4 and 700mm lens.   […]

Reader’s wildlife photo (and a ZeFrank video)

I have a hiatus on my backlog of wildlife pictures until I return on Saturday, but here’s one sent by Stephen Barnard from Idaho: it’s Boris, one of the two American kestrels (Falco sparverius) nesting in a box on his garage. (The female’s named Natasha.) No word about whether there are chicks yet: As lagniappe, […]

Readers’ wildlife photos

I’m delighted to have Stephen Barnard back, who took a hiatus from photography. Here are some of his photos from Idaho, along with his captions (indented): The weather and the lighting are improving so I’m back to taking some photos. First, an in-flight photo of a pair of Sandhill Cranes (Grus canadensis). They breed here […]

Cormorant fishing off the skin of a whale shark

I had to put up this video because it’s so cool and unusual (Matthew alerted me to it). It’s a cormorant grabbing remoras affixed to the skin of a whale shark off Cabo San Lucas, and a one-off video. (Remember that the whale shark, Rhincodon typus, is the world’s largest fish.) Now that is avian inventiveness! Earth Touch News […]

Readers’ wildlife photos (and video)

We have photos from four readers today. The first is from Stephen Barnard, whose documentation of a brood of gadwall ducklings was posted this summer. I believe eleven were hatched, and nine survived. What took them? Maybe an Onchorhynchus mykiss: Here’s a rainbow trout that may have been responsible for some gadwall duckling fatalities. Urban […]
