In this fascinating new book, Nick Davies describes the natural
histories of these brood parasites and examines many of the
exciting questions they raise about the evolution of cheating and
the arms race between parasites and their prey. Brood parasites
fill their armory with adaptations including exquisite egg mimicry,
rapid laying, ejection of host eggs, murder of host young, chick
mimicry and manipulative begging behavior: ploys shown by recent
research to have evolved in response to host defense behavior or
through competition among the parasites themselves. While many host
species appear defenseless, accepting parasite eggs quite unlike
their own, many are more discriminating against odd-looking eggs
and some have evolved the ability to discriminate against
odd-looking chicks as well. How is this arms race conducted? Will
defenseless hosts develop defenses in time, or are there
constraints which limit the evolution and perfection of host
defenses? And why are so few species obliged only to lay eggs in
host nests? Have host defenses limited the success of brood
parasitism, or is it in fact much more common than we suspect, but
occurring mainly when birds parasitize the nest of their own kind?
All of these puzzles are examined in descriptions of the natural
history of each of the groups of parasites in turn. Here is a book
with wide appeal, both to amateur naturalists fascinated by this
most singular and macabre of behaviors and by ornithologists and
ecologists interested in the evolution of ecology and behavior. The
story takes us from the classic field work earlier this century by
pioneer ornithologists such as Edgar Chance, Stuart Baker, Herbert
Friedmann and others, through to the recent experimental field work
and molecular techniques of today's leading scientists. We visit
brood parasites in Europe, Asia, Japan, Africa, Australasia, and
North and South America, to look at some of the worlds most
interesting birds and some of biology's most interesting questions,
many of which still beg answers from ornithologists in the future.
Brilliant illustrations by David Quinn illuminate the species
discussed, showing many behaviors never before illustrated and
conveying the thrill of watching these astonishing birds in the
wild.
