Abstract
The heart rate (HR) of a female Ferruginous Hawk was monitored continuously by telemetry under different handling-disturbance conditions. HR increased approximately threefold when the handler was outside the cage, and invariably reached a maximum (490-502 beats/min) when the handler was inside the cage. Near-maximal HR's were observed when the Hawk was restrained on the ground or held by the handler. On the other hand, hooding the bird during restraint resulted in a slowing of HR to 51-66% of the maximal rate.
