Ep. 262 : Birds at Rest with Roger Pasquier

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?
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.
