Birds at Rest is the first book to give a full picture of how birds rest, roost, and sleep, a vital part of their lives. It features new science that can measure what is happening in a bird's brain over the course of a night or when it has flown to another hemisphere, as well as still-valuable observations by legendary naturalists such as John James Audubon, Alfred Russel Wallace, and Theodore Roosevelt. Much of what they saw and what ornithologists are studying today can be observed and enjoyed by any birder.
Birds at Rest includes evocative black-white drawings by artist and illustrator Margaret La Farge.
From the poles to the tropics, how, when, and where birds sleep reflect the ecology and behaviour of each species, as well as their evolution from dinosaur ancestors. Some sleep briefly, their brain half awake, others spend long cold nights in torpor, a few can sleep while flying. Their roosting habits are also varied. Most birds sleep alone, some in pairs or families, while others in flocks of millions. Birds at Rest explains how each strategy works over the course of a season, a year, or a lifetime by providing protection, mating opportunities, information about food, and other survival benefits.
Birds at Rest discusses how environmental challenges such as artificial lights and noise, invasive species, and climate change are disrupting avian sleep and proposes solutions to ensure that birds get the rest they need.
