*BCAS Meeting: Crossbill Natural History and the Cassia Crossbill* We hope you will join us for our next *Boulder Audubon meeting this Tuesday, November 23*! During this talk, University of Wyoming ornithologist and evolutionary ecologist 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. Then the focus will shift to the sedentary Cassia Crossbill, a species Craig found on his way to a conference in Boise, Idaho. He will share with us some of its evolutionary history and ecology, and end by discussing its future prospects in the face of climate change, including a fire in the fall of 2020 that burned around a quarter 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. Craig is a Fellow of the American Association of the Advancement of Science, and received the E. O. Wilson Naturalist Award from the American Society of Naturalists and the William Brewster Memorial Award from the American Ornithological Society.
