Raptors
Raptors are formally classified into five families and include
birds-such as eagles, ospreys, kites, true hawks, buzzards,
harriers, vultures, and falcons-that are familiar and recognized by
many observers. These diurnal birds of prey are found on every
continent except Antarctica and can thrive in seemingly
inhospitable spots such as deserts and the tundra. They have
powerful talons and hooked beaks for cutting and tearing meat, and
keen binocular vision to aid in their hunting prowess. Because of
their large size, distinctive feeding habits, and long-distance
flight patterns, raptors intrigue humans and have been the subject
of much general interest as well as extensive scientific research.
Keith L. Bildstein has watched and studied raptors on five
continents and is well prepared to explain their critical
importance, not only as ecological entities but also as
inspirational tokens across natural and human-dominated landscapes.
His book offers a comprehensive and accessible account of raptors,
including their evolutionary history, their relationships to other
groups of birds, their sensory abilities, their general natural
history, their breeding ecology and feeding behavior, and threats
to their survival in a human-dominated world. Biologically sound
but readable, Raptors is a nontechnical overview of this
captivating group. It will allow naturalists, birders,
hawk-watchers, science educators, schoolchildren, and the general
public, along with new students in the field of raptor biology, to
understand and appreciate these birds, and in so doing better
protect them.

Vultures of the World
In Vultures of the
World , Keith L. Bildstein provides an
engaging look at vultures and condors, seeking to help us
understand these widely recognized but underappreciated
birds.
Bildstein's latest work is an inspirational and long overdue
blend of all things vulture. Based on decades of personal
experience, dozens of case studies, and numerous up-to-date
examples of cutting-edge science, this book introduces readers to
the essential nature of vultures and condors. Not only do these
most proficient of all vertebrate scavengers clean up natural and
man-made organic waste but they also recycle ecologically essential
elements back into both wild and human landscapes, allowing our
ecosystems to function successfully across generations of
organisms. With distributions ranging over more than three-quarters
of all land on five continents, the world's twenty-three species of
scavenging birds of prey offer an outstanding example of biological
diversity writ large.
Included in the world's species fold are its most abundant large
raptors-several of its longest lived birds and the most massive of
all soaring birds. With a fossil record dating back more than fifty
million years, vultures and condors possess numerous adaptions that
characteristically serve them well but at times also make them
particularly vulnerable to human actions. Vultures of the
World is a truly global treatment of vultures, offering a
roadmap of how best to protect these birds and their important
ecology.
