Tracking Cultural Evolution in House Finch Song, Part 1

The first bird song I ever recorded was that of a House Finch. When I was a kid growing up in Leominster, Massachusetts, the bird that nested behind my front porch lamp would fly out to a particular birch tree or the telephone wire and belt out a complex four-second warble over and over again.

How to Hide a Godwit

Marbled Godwits are common and conspicuous North American shorebirds. On its prairie breeding grounds, the godwit’s raucous call and proud flight display alerts all to its presence, and the species is equally obvious on its temperate nonbreeding grounds along both the Atlantic and Pacific coasts due to its gregarious nature and telltale alarm call. So how did such a charismatic species go largely undetected in Alaska until the 1980s?

Do Burrowing Owls Disperse Plague-Infected Fleas?

Western Burrowing Owls (Athene cunicularia hypugaea) and Pulex irritans, the so-called human flea, have a curious host-parasite relationship. Although we’ve known about it for some time, many details of their connection remain unclear, including why it appears mainly in the northwestern portion of the Burrowing Owl’s range despite the fact that both species have much broader geographic distributions.

Mr. Cairngorms

In 2013, while compiling information for a chapter on the contributions of ornithology to evolutionary biology, I carried on a lively correspondence, by email, with Adam Watson. Watson was a renowned Scottish ecologist, naturalist and conservationist who had worked with Vero Wynne-Edwards, a staunch promoter of evolution by group selection.  We have all of Wynne-Edwards …

In the Shadow of Men

In 1973, I was stranded for several days on a small island in Witless Bay off the southeast coast of Newfoundland.

Landing on Green Island was sometimes difficult and the days were short as the local cod fishermen—Bill …

Dirty Birds

As a teenager, in the 1960s, I spent much of my spare time during the school year hanging out at the Royal Ontario Museum (ROM), not far from my family’s home in Toronto.  The denizens of the bird/mammal prep room in the basement of the museum—Don Baldwin, Hisham Badran, Jim Borack and Rolph Davis—took me …

How Vulnerable are California’s Great Gray Owls to Wildfire?

Throughout western North America, the combination of longer, hotter dry seasons and dense forests is yielding more frequent, larger, and more severe wildfires, including immense “megafires.” Habitat loss from increased fire activity could put wildlife species that depend on mature forest at risk.
