Lorna Gibson: Birds Up Close, Gebunden

Klappentext

A renowned engineer reveals the marvel of how birds work---from the tips of their beaks to the sheen of their tailfeathers.

Consider feathers: They define birds' wings, enabling flight. They insulate against cold. They repel water. They even control sound. And how feathers work is just one aspect of the wonders of birds explained by pathbreaking researcher and lifelong birder Lorna Gibson in Birds Up Close .

Feathers, bones, bills, eggs, flight: all come in for scrutiny in this engaging book. What produces the iridescence of plumage? How does the internal structure of a bird's bones make them lightweight? How do different birds use their bills and tongues---from woodpeckers penetrating the holes they drill to hummingbirds imbibing nectar, to sandpipers needling the sand, and to phalaropes drawing water droplets containing plankton into their mouths without sucking (no lips!)?

Drawing on her expertise and personal experience in both engineering and ornithology, the author explores the hidden microscopic structures and engineering principles that keep birds aloft and alive---how an egg is formed, how a bird generates lift; how raptors soar and glide, albatrosses fly thousands of miles, hummingbirds hover, puffins and penguins "fly" underwater. She also considers the longer view of birds in their habitats and natural history. Her up-close look at avian mysteries provides a perspective like no other for the expert ornithologist and curious observer alike.
