Dr. Dave Oleyar, HawkWatch International’s Senior Scientist, is a conservation biologist and population ecologist with over 20 years of experience working with raptors and other birds in western North America. Join Dave to hear about the work HWI does with a focus on two projects that include sites in Arizona. HWI and the NPS monitor raptor migration each fall at Yaki Point on the south rim of the Grand Canyon. Find out what we’ve learned here and at other migration sites across the west. Oleyar also leads studies of small forest owl communities and the tree hollows they use to roost and nest. This work involves citizen scientists and takes place in the Chiricahua Mountains of southeast Arizona and in northern Utah.
