Description: Male prairie falcon imprinted on its human trainer voluntary deposits semen by pressing its cloaca against a specially designed collection hat. Note that the falcon's feet are closed so that its talons are not exposed during "copulation". Semen deposited in this way can be recovered in a capillary tube and used for evaluating semen quality and for artificial insemination. This is a valuable conservation tool that contributed significantly to the restoration of the once endangered peregrine falcon.
