Brood Parasite

Winter Lecture Series: How to Avoid Raising Another Bird’s Chicks

Date: Sunday, February 4
Time: 2:00 pm – 3:00 pm


Dr. Underwood’s lecture will explore brood parasitism, which is an unusual reproductive strategy in birds where females lay their eggs in other birds’ nests and leave all parental care to these foster parents or hosts. Because raising parasitic young is costly to host birds, this favors the evolution of behavioral defenses against parasitism. Dr. Underwood will focus on his experimental research on how and why some host birds can recognize and eject a parasite’s eggs.

Todd Underwood earned a Ph.D. in Zoology from the University of Manitoba in Canada and is Professor of Biology at Kutztown University. He teaches courses including ornithology and vertebrate biology and studies the behavior and ecology of birds. His research focuses on brood parasitism, the impact of alien plants on birds, bird feeder hygiene and the biology of birds that breed in nest boxes.

Walk-ins welcome as space allows.
