His Ph.D. dissertation is the monograph on golden eagle behavior. In Behavior of the Golden Eagle, the action patterns and activities of the golden eagle are described and most are illustrated in great detail.
We aged chicks based on behavior and plumage (Ellis 1979) and sexed them based on bill depth and head, hallux claw, and tail length (A. Harmata, pers. comm.). Data collection.-We located active Golden Eagle nests by aerial and ground surveys. We entered each of the 20 eagle … This passion led to extensive travel as a field biologist or ecotourism guide. However, if a mate dies or does not return to the nesting site for the breeding season, studies show that the surviving eagle generally will find a new mate very quickly. Harpy eagle, like Bald eagle, is also known as the American Harpy eagle. Perhaps you are confused by the maturing age of a Bald Eagle when it grows from a chick to an adult. Lustrous gold feathers gleam on the back of its head and neck; a powerful beak and talons advertise its hunting prowess. Harpy eagle facts about its group show that the bird is a member of genus Harpia. No The Golden Eagle is a separate species of Eagle than the Bald Eagle. N. John Schmitt has had a life-long interest in birds and art. Eagles engage in significant courtship and pair bonding behavior. His publications exceed 300 articles, chapters, or books, including three volumes on crane research. Once a pair has succeeded in breeding, the pair will likely remain together for many years. Eagles and falcons have taken him to fifty nations and five continents. This ethogram for the Golden Eagle (Aquila chrysaetos) provides a thorough description of ~100 relatively short-term and discrete “action patterns” (e.g., “head-bob”) that form the basis of more complex and longer-term activity patterns, such as nesting or migration.The ethogram is organized into 12 nonexclusive “classes” of behavior, within which the action patterns are nested. There is also a brief chapter on the history of behavioural studies as they apply to raptors.

Names and titles are given for each action pattern, and those that are most useful in determining health and level of disturbance are discussed. This ethogram for the Golden Eagle (Aquila chrysaetos) provides a thorough description of ~100 relatively short-term and discrete “action patterns” (e.g., “head-bob”) that form the basis of more complex and longer-term activity patterns, such as nesting or migration. You're most likely to see this eagle in western North America, soaring on steady wings or diving in pursuit of the jackrabbits and other small mammals that are its main prey. We considered a priori that preening by a tagged Golden Eagle would indicate altered behavior if it was excessive based on percentage of time spent preening compared to untagged mates or if it included aggressive attempts to rearrange or remove a PTT package by using its bill or foot (Booms et al. Cutting down of lofty trees means extinction of harpy eagles’ habitats. 2011). The eagle is largely associated with the Crested Eagle or the New Guinea Eagle. The bird belongs to the Neotropical species of eagles. The Golden Eagle is one of the largest, fastest, nimblest raptors in North America.
