In this day and time, it does not seem possible that the American robin was once shot for food however, it is true. It seems that up until the adoption of the Migratory Bird Treaty Act on March 4, 1913, each year thousands of robins were legally harvested for food.
This practice was more common in the South than anywhere else was in the country. The reason for this is large flocks of robins spend the winter throughout the Southeastern United States. Some of these flocks are tremendous in size. One year on the Piedmont National Wildlife Refuge/Rum Creek Wildlife Management Area Christmas Bird Count, observers recorded an estimated 2 million birds flying southward along the Ocmulgee River.
While I have never personally eaten one of these large songbirds, I once worked with a colleague that grew up in rural Arkansas. He said that each year his mother canned American robins shot by members of his family. According to him, the birds were quite tasty.
