Hidden at a small liberal arts college in Pasadena, CA is the largest collection of Mexican birds in the World. Moore Laboratory of Zoology has more than 65,000 Mexican bird specimens, most of which were collected by a single man named Chester Lamb from 1920s to the 1950s. This collection represents a snapshot in time of what Mexico’s bird fauna looked like before the country went through its major industrial revolution. Using this one-of-a-kind collection, Moore Lab curator John McCormack is walking in Lamb's footsteps to find out how and why Mexico’s bird fauna are changing and adapting.
