Focus

I am evolutionary biologist conducting research primarily on social selection (including sexual selection). I have worked mainly on birds, fishes, insects, and mammals (including humans), but I am a naturalist at heart and usually choose study species that I think will best answer the questions that interest me.

I am currently working on a study of sex ratio and the evolution of body size on Gray-crowned Rosy Finches on St Paul Island, Alaska, and a study of dawn choruses in birds at several sites in France, Canada, the United States and Australia.

I also study the history of ornithology, and maintain a website on that topic for the American Ornithological Society. I maintain a different website for a book on the recent history of ornithology that I wrote with Tim Birkhead and Jo Wimpenny in 2014.

I retired from my faculty position at the end of 2019. I am now Emeritus Professorand am devoting full-time to my own research and writing. I will no longer be supervising graduate students except possibly as cosupervisor with one of my colleague-collaborators (Drs Paul Martin, Fran Bonier, Steve Lougheed, or Adam Chippindale). If you are interested in working with me please write to one of those people first.,

I don’t update this website more than once a year so if you are interested in my recent thoughts, ideas and photos follow me on Twitter at the links to the right.
