Evening Grosbeaks Coming to a Feeder Near You? – Nov. 5, 2018
Keep an eye out for Evening Grosbeaks this winter. These stout finches are irruptive migrants, meaning they make very erratic movements south from their boreal habitats into the continental United States in some winters, when they can become common at backyard feeders. These irruptions formerly happened every 2–3 years in the eastern United States but have become less frequent, particularly in the East, since the 1980s. Western subspecies migrate to lower elevations for the winter.

This Could Be the Winter You Get Evening Grosbeaks at Your Feeder
A poor summer for conifer seeds in eastern Canada could spell a great winter for feeder watchers in eastern North America. Already, Red-breasted Nuthatches, Purple Finches, and Pine Siskins are showing up in unusually high numbers. Evening Grosbeaks could make their strongest showing in the Northeast and Mid-Atlantic in nearly two decades. Get ready for great winter birding with our predictions and tips.
