In the past 50 years, we have lost three billion birds across North America, with the steepest decline in the evening grosbeak population. Scientists began studying wintering evening grosbeaks in Western Pennsylvania in 2017 to learn more about their natural history, ecology and migration movements. They are a species that follows irruptive migration – sudden, but regular mass movements in response to changes in their environment. This winter, we have seen a widespread irruptive migration of boreal finches, including grosbeaks, in numbers we haven’t seen in decades.

Join David Yeany, avian ecologist at the Western Pennsylvania Conservancy, for a free webinar to learn about this year’s finch superflight and how we are using new technology to track winter movements of evening grosbeaks and inform the conservation strategies to help protect this species.
