Reviews:
-Roots, who is a zoo director, explains the physiology behind hibernation then characterizes the hibernation behavior of fish, amphibians, rodents, bears, bats, and some cold-blooded mammals. A short but surprising chapter explores daily torpidity among hummingbirds, swifts, poorwills, chickadees, and vultures. Both black and white photographs and color plates are provided, making the book particularly suitable for high school and public libraries.

-This title has been reviewed jointly with Nocturnal Animals and Hibernation, both by Clive Roots.....These three titles fill a niche. Most available books on flightless birds, nocturnal animals, and hibernation are for a juvenile audience, or they focus narrowly on particular animals (e.g., penguins) rather than giving a broad overview. Undergraduates in zoology will find these books useful. Recommended. Lower-/upper-level undergraduates, two-year technical program students, and general readers.
