There’s a flock of American Robins in my yard; don’t these birds migrate south for the winter?
As with many birds, the wintering range of American Robins is affected by weather and natural food supply, but as long as food is available, these birds are able to withstand quite severe cold. American Robins do migrate, but their year-round range covers the continental United States and into Southern Canada.
In winter robins form nomadic flocks, which can range in size from 50 birds in the north to thousands in the south. Sometimes the flocks break up in the day while foraging and then gather up again at night to roost in trees. To attract robins, try serving dried or fresh fruit and providing a source of water.
