Readers’ wildlife photos

This is the second set of photos taken by reader Joe Dickinson on a recent trip to the Merced National Wildlife Refuge in California’s Central Valley (his first set is here). Joe’s captions are indented.  We’ll begin with another raptor, the diminutive and colorful American kestrel (Falco sparverius). Several shots of snow geese (Chen caerulescens) and Ross’s geese […]

Readers’ wildlife photos

We have some photos from New Zealand sent by reader Keith Cook, whose comments and IDs are indented. These attachments are a collection of pics from around my home and the local beach. I include some landscapes a la Stephen Bernard, seeing and raising his with a South Pacific sunrise or two… and a moon rise […]

Readers’ wildlife photos

Be sure to send me in your good wildlife photos. Thanks! Evolutionary biologist John Avise sent another batch of bird photos, and they’re my favorite birds. His notes and IDs are indented. Note that although the males diverge strongly in their appearance, females often look pretty much the same. This indicates that the male divergence (and […]

Hawk and owl fight over a nest

Reader jj sent a video of an owl and a hawk fighting for a nest. The owl eventually won. jj’s notes: Perhaps others have sent these links; in case not, here’s a link to a cool video showing a pair of Great Horned Owls displacing Red-tailed Hawks from their nest.  At the end of the […]

More birds with “teeth”

by Greg Mayer A few days ago, in my post on the ducks of San Diego, I noted that mergansers were my favorite ducks, in part because of their tooth-like bill serrations, and that I knew of no other birds (except sort of in geese) that had such modifications of the bill. Well, of course, […]

Readers’ wildlife photos and video

We have two contributors today. The first is Charles Sawicki, who found a beaver! His notes, and those of Stephen below, are indented. Here are photos and a movie of a rescued beaver. This North American beaver (Castor canadensis) was found early last summer as a tiny kit crying in a drainage ditch. Beavers in distress […]

Radiolab on sexual selection in birds

Here’s the latest Radiolab podcast, this time about sexual selection in birds and about Richard Prum’s revival of the idea of “runaway sexual selection,” which he calls the “beauty happens” theory. (It’s in his book, The Evolution of Beauty: How Darwin’s Forgotten Theory Shapes the Animal World—and Us.) I’ve written about Prum’s book before, and about my […]
