I have had a lot of conversations with biologists and ornithologists over the years, trying to learn about how different animals sleep. Are the functions of sleep in humans similar to similar animals? What about different kinds of animals, like insects, or birds?

More recently I have seen the Canada Geese along the Eramosa River where I live, standing or sitting still on the frozen river and wondered what’s up with the one-legged standing? When I got to thinking about birds resting, roosting and sleeping, I realized that I had a bunch of questions. Sometimes a book comes along with some good insight into the subjects I am wondering about, and at this moment, it was Roger Pasquier, and his new book Birds at Rest: The Behavior and Ecology of Avian Sleep, which helped to answer many of my questions. I arranged for an interview was very glad to talk to him.

Do small songbirds have any special adaptations for sleeping through long freezing winter nights? Does photoperiod change the amount of time birds sleep? How does the changing climate affect birds at rest? Do birds dream?

Roger Pasquier has taken the time to collect the information from a ton of various studies into avian rest and sleep and consolidated them into a useful and interesting book, and then taken the time to discuss some of this research on the show.

Again, I am forever grateful to the folks who can help us, me, learn to better know the land.
