Raptor Banding

We are able to gain valuable information on overall populations through raptor counts (Link to raptor counts), however this technique gives little insight into the ecology and migration of individual raptors. By placing a lightweight metal band on the leg of a migrating raptor, this individual has the potential to provide information on its movements and life history. While birds are in the hand, researchers can determine the individual’s age, condition, and take helpful measurements to determine the raptors sex (males and females of most species look identical, but are different in size).

By also collecting a small sample of body feathers, biologists can use stable isotope signatures in the bird’s feathers (Link to isotope stuff) to estimate the latitude where the bird was raised. Research at the FKRMP has been important in the development of this new tool for raptor migration researchers to learn the origins of migrating birds.
