Dr. Craig Benkman will discuss some of the more striking features of crossbills, a group of birds he started studying in 1982. This includes how crossbills use their crossed mandibles to feed, why there is such great size variation among crossbills, and why crossbills are usually nomadic and breed at unusual times. Dr. Benkman will shift focus to the sedentary Cassia Crossbill, a species he found on his way to a conference in Boise, Idaho. He will discuss some of its evolutionary history and ecology, and end by discussing its future prospects in the face of climate change including a fire this fall that burned nearly half of the Cassia Crossbill’s habitat.
Craig Benkman is an evolutionary ecologist and ornithologist, and a Professor and Robert B. Berry Distinguished Chair in Ecology at the University of Wyoming.
