Three female Evening Grosbeaks were the featured guests today at the feeding station of New Jersey Audubon’s Scherman Hoffman Sanctuary in Bernardsville. When the birds arrived, Susan Garretson-Friedman spread the word via various media outlets so that other people were able to watch the birds feed, preen, fly around, perch, call, etc.

The Evening Grosbeaks visiting New Jersey this season, are most likely of Type 3, the eastern population. Five different sub-species of Evening Grosbeaks are thought to exist. Here is a link describing the different sub-species’ vocalizations from the Earbirding website:
Evening Grosbeak Call Types.

Following is a map showing the range of the five sub-species of Evening Grosbeak, created by Kei Sochi. See Birding, November 2012, pp. 34–40, for full details.

Here is a size comparison between an Evening Grosbeak on the left and an American Goldfinch on the right. Both species are in the Fringillidae family. (Click on the photos for larger images.)
