5What animal is descended from dinosaurs, pollinates plants, flies thousands of miles annually, can weigh less than a dime or as much as 340 pounds, and can even remember when humans have been kind or mean? Meet the bird! Birds are extraordinary creatures and they live almost everywhere on earth. With over 10,000 bird species, there's tremendous variety in sizes, shapes, colors, and abilities. And besides being beautiful to look at, birds are a critical part of our ecosystems and support biodiversity on our planet. Through poetry and sidebar text, F is for Feathers: A Bird Alphabet explores all aspects of bird life, from physical characteristics to types of habitat. Additional information includes a glossary, ways to protect birds and their environment, and tips on how to be a good bird watcher.
