Greig, Emma: - Dr. Emma Greig is the team leader for the Cornell Lab of Ornithology's Project FeederWatch, a major citizen-science program that engages bird watchers in a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America. FeederWatch data help scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance. Emma holds a Ph.D. from the University of Chicago and has studied birds in Australia, Malaysia, and most recently, the Sonoran Desert, the hottest desert of North America.
