This one enjoys millet, black oil, and striped sunflower seeds. Some of my bird books say that robins in the North eat seeds. Anne Hagge, Jacksonville, Arkansas.

Robins are so adaptable that they can survive almost anywhere.
Part of their adaptability is a behavioral willingness to eat diverse foods. Robins are masters at finding and eating whatever food is available. Their diet may be as variable as that of American crows. Tom Brilla, Mason, Wisconsin. Most species reserve what little aggressive behavior they can muster for trying to escape when captured.
