Blackbirds Return To Cornell Feeders During Morning Feeding Frenzy – March 5, 2020

Red-winged Blackbirds, European Starlings, and Common Grackles join a host of forest residents in front of the Cornell FeederWatch cam. Many individuals of these species that breed in the northern latitudes of their ranges (including those in Ithaca, New York) tend to make short migrations south for winter. As spring approaches, they return to Sapsucker Woods and feast at the feeders in the Treman Bird Feeding garden.
