Survival, Dispersal, and Long-range Movements of Prairie Falcons

Collage of Prairie Falcons

Introduction
We attached platform transmitter terminals (PTTs) to 10 adult Prairie Falcons (Falco mexicanus) from the Snake River Birds of Prey National Conservation Area (NCA) each year for 4 years (1999-2002). PTTs transmit signals to be received by polar-orbiting satellites, from which location estimates of the birds can be derived from anywhere in the world. For a description of how satellite telemetry works, see "Crane Watch Page". The information gathered will provide critical information for managing the species in the NCA and throughout its range. Our results also will have implications for determining the status of the Prairie Falcon throughout its range and will assist state and federal wildlife agencies throughout the West in setting appropriate falconry harvest regulations. The information gathered also will contribute to the overall knowledge of this species' basic biology and population dynamics. The study was conducted by a uniquely qualified team of scientists who are recognized experts in the fields of satellite telemetry and Prairie Falcon ecology.
