Birds evolved about 150 million years ago, and today they are the most diverse and colorful land vertebrates. In my group, we are fascinated by the ecological and evolutionary processes that contribute to avian diversity. In the field, we are establishing a system for studying color perception in wild hummingbirds in the Rocky Mountains. These tiny iridescent birds lead colorful lives, performing spectacular courtship dives and pollinating diverse wildflowers. We also study the avian egg, a remarkable structure that is built to break. The eggs laid by stealthy cuckoos and flightless emus offer insights into avian behavior and evolution.
