Readers’ wildlife photos

Reader “Siggy in Costa Rica” (his posting handle), sent us these photos from his eponymous country; his notes are indented. These are Red-legged Honeycreepers [Cyanerpes cyaneus], one female and 3 males, helping themselves to some bananas on my patio. [JAC: note the extreme sexual dimorphism!] And a closeup of a male. A Rufous-tailed Hummingbird (Amazilia tzacatl) […]

Spot the three caterpillars!

This (from a tw**t by John Horstman) isn’t very hard at all, but it does show the crypsis that never gets old to me: h/t: Matthew Cobb

Readers’ wildlife photos

Some miscellaneous photos from the Galapagos First three are Sally Lightfoot crabs (Grapsus grapsus).  Pic 1 molting, pic 2 reproducing, pic 3 hanging out – all shot on Fernandina: \ Red billed tropicbird (Phaethon aethereus) […]

Readers’ wildlife photos

I request once again that readers send me their good wildlife photos. Reader Tony Eales from Australia sent some lovely bee photos; his notes are indented: It’s been a while but the insect photography is going great. I’m particularly enamoured of native Australian bees, apparently, I’m told, there are something like 1600 species in Australia. […]

Readers’ wildlife photographs

I’m back in Chicago, so it’s time to start sending me your wildlife photos: the tank is getting a bit too low for my comfort. Thanks! Today I’m putting up the final installment of naturalist/biologist/photographer Lou Jost’s photos from the Tambopata Research Center in Peru. His notes are indented. I especially love the decoy spider in […]

An amazing leaf-mimicking spider

If you’re a regular, you know that all the biologists who post here love mimicry. I’ve tried to explain why: it shows the power of natural selection and the degree of perfection that natural selection can attain (i.e., how closely something can come to mimic the background or another animal—the “target”), and the very remarkable and unpredictable […]

A snake-mimicking spider

by Greg Mayer Matthew shared with me an interesting video of a spider from Singapore that looks like the head of a snake. The videographer, Nicky Bay, is most interested in the pulsation of a dark region below the ‘eyes’, but to me it’s the resemblance to a snake that is most striking– the ‘nostrils/loreal […]

Readers’ wildlife photograph

We have only two photos today, but they’re both lovely. The first is a picture of one of my favorite bird species, the sexually dimorphic wood duck (Aix sponsa)—a striking instantiation of sexual selection: the coevolution of male traits with female preferences for those traits. One wonders, as in all such cases, what features of that gaudy male gave […]

Readers’ wildlife photos

Reader Robert Lang made a trip to Costa Rica earlier this year, and sent some photos of arthropods. His captions are indented: We saw fewer arthropods (other than butterflies) than I expected in the various wet forest environments, but the ones we did see were quite spectacular. The Blue Land Crab (Cardisoma guanhumi) was shot […]

Readers’ wildlife photographs

Jeffrey Lewis sent us some photos from Bonaire, and there will be more. The subjects are diverse! His notes are indented. Perhaps hese aren’t up to the normal quality of your Reader’s Wildlife photos, but perhaps the subject matter will make them worthwhile since underwater photos seem to be rare in the series.  These were all […]
