Readers’ wildlife photos (and videos)

Stephen Barnard from Idaho is back with some lovely photos—and two videos as lagniappe. His captions and IDs are indented. The first four are mallards (Anas platyrhynchos) in flight. Migratory mallards are pouring in from Canada and parts north. There will soon be thousands. Duck hunting season, popular here, starts October 19. You’ll be happy […]

Readers’ wildlife photos

Thanks to the several readers who responded to my plea for wildlife photos. I now have at least a week’s worth. One of the kind respondents was Stephen Barnard, who hasn’t been here for a while. He sent a batch of lovely photos, and I’ve indented his notes below. A few “wildlife” photos for you […]

I’m happy to report that Stephen Barnard is back with a spate of pictures—of fishing. Stephen’s notes are indented: During the seemingly endless pandemic I’ve been doing little more than fly fishing and farm chores, and photographing fish. All these are rainbow trout (Oncorhynchus mykiss). The exceptions are mayflies: a Callibaetis dun and a comparision […]

Two species produce viable hybrids even though they diverged 150 million years ago

Here’s an amazing paper—though the striking part isn’t sufficiently emphasized—reporting artificial hybridization between two long-diverged species, and the resulting appearance of viable hybrids despite what must be substantial genetic divergence between the components of a hybrid genome. Here are the two species involved, the Russian sturgeon (Acipenser gueldenstaedtii), a source of meat and caviar, and a […]

During the pandemonium surrounding the entry of Honey and Dorothy’s broods into Botany Pond at the beginning of May, reader David Campbell sent me some wildlife pictures. And, as sometimes happens, I forgot to put them in the “readers’ wildlife” folder. He reminded me, and, with apologies, here are some late photos. David’s captions are […]

Juvenile striped eel catfish form a coordinated, roiling ball to avoid predation

Both Matthew and reader Dom sent me this link to The Colossal describing and showing another amazing animal behavior, this time in the striped eel catfish (Plotosus lineatus), a smallish species (average size about 14 cm) found in the Indian and Pacific Oceans, as well as the Mediterranean where it’s a recent invader. It’s the […]

Today’s photos of animals, all from diverse groups, come from David Campbell, who relates a scary mallard story too—though it turns out all right. David’s captions and tales are indented: Another batch of photographs.  The duck narrative has a happy ending although I didn’t expect one when it happened. Mantispid (Dicromantispa interrupta). Convergent evolution at […]

Stephen Barnard, whose photos may have initiated this regular feature, has been taking a break and fishing. But today he’s back with a new batch of pictures of birds, fish, and flies. His captions are indented. All photos except the last are in chronological order. Sandhill Cranes (Grus canadensis) This time of year they gather […]

Readers’ wildlife photos

Stephen Barnard has been busy fishing, but he favors us today with a new batch of photos from Idaho. His captions are indented. The first four are rufous hummingbirds (Selasphorus rufus). They migrate through in August and put on quite a show at the feeders. They’re gone now. Next is a moose (Alces alces) across […]

We have some underwater photos today, pictures taken by reader Peter Klaver. His descriptions are indented, and note that there are several of his movies linked to the text. Last month two friends and I had a week of diving in the Red Sea. The underwater life there is simply stunning. The highlight of the […]
