Evening Grosbeaks Feeding Station

Fall 2020 brought a "Finch Superflight" to the Eastern US. Evening Grosbeaks are having an irruption south of the boreal forests in numbers not seen for more than 20 years due to high reproductive success from an abundance of several growing spruce budworm outbreaks in Canada and winter tree seed shortages.

Western Pennsylvania Conservancy’s Pennsylvania Natural Heritage Program has been collaborating with the Carnegie Museum of Natural History at Powdermill Nature Reserve to continue a third year of research on wintering Evening Grosbeak movements at the Forest County site seen in this video.

Grosbeaks are gregarious and have voracious appetites, and you can see birds from this study population at a Forest County feeding station. This video was captured by WPC Avian Ecologist David Yeany.
