Dr. Sean Williams – Redpoll Identification and Biology
February 11, 2021 @ 7:00 pm - 9:00 pm
Join us for an evening with Dr. Sean Williams, professor of Behavior, Ecology, and Ornithology at College of the Holy Cross, as he discusses his most recent research Variation in seed availability of the boreal forests drives variation in redpoll abundance in New England winters. In some years, redpolls “irrupt” into southern New England, allowing for unique opportunities to study them. In this talk, we will explore the biology of their annual cycle and the conditions that lead to irruption events. In addition, we will learn about the identification of four taxa that occur in North America: nominate and Greenland Common Redpolls, and Coues’s and Greenland Hoary Redpolls. Dr. Sean Williams is Visiting Assistant Professor of Behavior, Ecology, and Ornithology at College of the Holy Cross, Secretary of the Massachusetts Avian Records Committee, and the holder of several Massachusetts bird count records.
