Peacock physics

We have a new paper out! Biomechanics of the peacock’s display: how feather structure and resonance influence multimodal signaling In this study we describe the rapid feather vibrations that peacocks use during courtship. These vibrations – at a rate of about 26 Hz on average – represent a substantial mechanical and metabolic challenge for... More

SICB Portland

Here is the poster we presented at SICB Portland last week on the biomechanics of peacock displays (click to enlarge): I think it turned out pretty well, although I’m not sure it could stand alone without an interpreter. We had a constant stream of awesome visitors. My coauthor Suzanne brought feathers and a model... More

Peacocking on Parliament Hill

Here’s my poster from the Evolution conference in Ottawa: The colours are a bit off in this shrunken version, but you can download a larger PDF version here. The poster covers some of my work on the lesser-known green peacock (a close relative of the familiar blue variety). Green and blue peafowl have markedly different body colours,... More

Life imitates [filmmaking] art

Congratulations to Myra Burrell – her peacockumentary has been short-listed for the Animal Behavior Society’s film festival! Myra, a veteran of the natural history film program at the University of Otago in New Zealand, traveled to California with me in 2010. She helped with peacock field work, capturing more females than anyone thought... More

How I learned to respect the peahen

Written for the Los Angeles Arboretum. Meep meep? More like “Honk honk!” Arboretum regulars will no doubt recognize the call of a startled peahen, but you may not be aware of the clever ways they use it. Not that they try to boast or taunt the enemy, necessarily, but I’m starting to think that... More

Elections are like peacocks

Both are loud, and both cause colourful flashy things to pop up on lawns everywhere. And much like elections, the peacock’s train is a costly endeavour. The species might be better off in terms of survival and abundance if they could just do away with those feathers. In terms of sheer waste, they remind... More

Furious about eyespots

I think I flubbed an interview this week. My supervisor Bob and I just published a paper that is getting some press, because it addresses a recent controversy about the peacock’s train1. Eager for the interview with Nature News, I wasn’t exactly prepared with good lines for the reporter to go on – and I... More

A case of mistaken celebrity

They all look the same to us. Celebrities, that is. And by us, I mean academics. The proof starts with peacocks. Last fall, I was working on some measurements I took of the crest ornament in these birds. Peafowl have this funky little fan of feathers on top of their heads, and though it’s... More

Deep archives: Irreducible beauty

                              Were peacocks designed with this kind of audience in mind? A while back I was searching for images of peacock feathers on Google, and I stumbled upon this article. It’s a piece by Stuart Burgess, an engineer who is head... More

Deep archives: Lek perspective

Males display in the “Wild Asia” exhibit at the Bronx Zoo, which can only be seen by riding the zoo monorail. The structure behind the birds is the monorail track. I’ve had some success on this trip after all. The weather was perfect for my model experiments yesterday (sunny, warm, not too much wind),... More

Deep archives: New York on foot

I’m back at the Bronx Zoo now, with the model peahen, attempting some more behavioural experiments. My first day was both good and bad. I had no trouble finding my accommodations on the zoo grounds last night – I’m staying in the “Bat Cave”, so named because of the bats. (Not really – the... More

Deep archives: The Californians, in pictures

Although I’m very happy to be back in Canada (having decided that Los Angeles is a terrible place to live, mostly because of all the driving), I have to admit that the people of California were quite friendly. I found the peafowl to be equally amenable. Since mating activity was finished during my last... More
