Dr. Gary Graves is a research zoologist and curator of birds at the Smithsonian National Museum of Natural History where his research focuses on the ecology, biogeography, and evolution of birds. His early childhood fascination with birds led to graduate studies at Louisiana State University and Florida State University: "I am unapologetically curious about natural history and the ways that natural history observations catalyze important ecological and evolutionary discoveries." His dissertation work focused on speciation of birds in the Andes Mountains of Peru. He has also conducted fieldwork in Brazil, Ecuador, Panama, Colombia, Polynesia, Canada, and in more than half the states in the USA. His current research efforts are split between the analysis of complex data sets based on the collective resources of the World's great museums and conducting field research in Jamaica, the great forests of the eastern USA, and in the Sonoran Desert.

About Raptors (Orders Falconiformes and Accipitriformes): Feeding

The classic raptor is an eagle with its sharp claws (talons) clutching a fish. Most raptors are powerful flyers who swoop down and use strong legs and talons to carry prey off (raptor = one who seizes and carries away). However, feeding varies depending on habitat. Raptors that live in open habitats with a view of the ground glide (soar) in the sky looking for prey. Some close their wings to plummet like missiles towards prey. Raptors who live in bushy habitats may hunt from perches, waiting on a branch until prey is spotted. A common rural sight is raptors perched on power lines along highways, watching for prey below. Some raptors have camouflaging plumage and rely on ambushing their prey from a hidden position. A subset of raptors, the vultures, feed on dead animals (carrion). All raptors have keen eyesight, allowing them to spot prey from as far as several hundred meters.
