Potoo mimics leaf blowing in the wind

Potoos are some of the most cryptic birds around. This video, which isn’t on YouTube, was made by Ciro Albano and shared by Novataxa (link provided by Florian M.). Click on the screenshot below to see a short but stunning video of a Rufous Potoo (Nyctibius bracteatus) rocking on its perch, apparently mimicking a twig or leaf […]

A new and bizarre form of mimicry: plant seeds mimic shape and smell of animal feces to facilitate dispersal by dung beetles

Mimicry is a recurring subject on this site, mainly because I’m fascinated by the precision with which natural selection can mold animals and plants to look like things they’re not. We’ve also seen examples of plants mimicking animals before, as in the orchids that mimic bees and wasps, fooling randy insect males into trying to copulate […]

Readers’ wildlife photographs

First, we have three birds, part of a large series (more soon) by reader Damon Williford: Three members of the cuckoo family breed here [South Texas], including the Yellow-billed Cuckoo, Greater Roadrunner, and Groove-billed Ani, which gets my vote for the goofiest looking bird in the world (but possibly tied with the Hoatzin for that […]

The wonderful world of ant mimics: photos by Alex Wild

Should I have called this post: “You won’t believe these animals that look like ants!”? I won’t reiterate the many reasons why I love mimics, and why every evolutionary biologist (or even admirer of nature) should, too. Just go over to photographer/entomologist Alex Wild‘s lovely “ant mimic” page to see the diversity of taxa that have evolved to […]

Readers’ wildlife photos

This week will be the last for a while in which I show readers’ wildlife photos, but keep sending them in, though I’m going to ask readers to restrict their emails to me when I’m on the road, as my email access will be spottier. Continuing from yesterday, we have Swiss reader Jacques Hausser’s second […]

Two Sunday morning tw**ts

Here are two tw**ts that Matthew Cobb (who had insomnia last night after nightmares about his young cat Harry dying [Harry is fine]): This one has a cute gif, but I don’t understand the title at all. Can any reader furnish a good explanation? and That species, known from Sri Lanka and southern India, is also […]

Parrot cries like a baby

Looks like today’s an almost all-biology day, which is fine with me; we need a day without godless ranting! To finish off our bird theme, we have this video of a green parrot that has obviously cohabited with a baby. I don’t know the species, but I’m SURE some readers do, so put the answer […]

Pupa in Trinidad mimics snake (and moves!)

This piece, from nerdist. com, describes one of the more amazing cases of mimicry I’ve seen. Look at the picture below, and see what you think it is: It’s not a snake, despite the very snake-y appearance of the thing. It has eyes (fake), the eyes even have a “glint” in them (fake), it has a […]

Chemical mimicry in an aphid

I’ve posted a lot about morphological mimicry in animals: the evolved resemblance of one species’ appearance to that of another, or to the environmental background. This mimicry can serve to protect animals from being spotted by predators, or, if you’re a predator, to hide yourself from your prey. The latter situation, in which animals resemble something else […]

Spot the canyon tree frogs!

by Matthew Cobb This picture was taken by @NashTurley and posted on Tw*tter about an hour ago. I can see eight tree frogs. How about you? Nash kindly mailed me the his-res version of the phot and added: I found these along a river in Sabino Canyon just North of Tucson, AZ. It’s a beautiful oasis […]
