BirdNote; Mysterious Disappearance of Evening Grosbeaks
Description:
In 1987, when Project FeederWatch began, Evening Grosbeaks were among the most common birds at birdfeeders during the Northeast winter. Now they're completely absent in many of those same areas. In the West, too, they're showing up in reduced numbers. Why have so many Evening Grosbeaks disappeared? The reasons aren't clear, and more research is needed. Citizen science, the information many backyard birdwatchers supply to Project FeederWatch, has raised the conservation alert about these birds. The season starts again in November.
