The ecology of co-migrating raptors and songbirds remains a great interest of mine. I spent numerous seasons watching and catching hawks, owls, and songbirds as they passed through the Manzano and Sandia Mountains of New Mexico. The stopover patterns, foraging strategies, and migration strategies of these birds mostly remain a mystery, but slowly we are piecing some of it together. I also am collaborating with ornithologists at the Cornell Lab of Ornithology to study bird migration using the eBird database.
