This was the first bird that I prepared. Robins are thrushes (family Turdidae). All Turdids have slender bills adapted for eating insects, berries, worms, etc. Robins may be seen roving in large groups in their wintering areas, foraging for food. Once, in the heart of a Chicago winter, I saw a large flock descend upon a tree loaded with red berries. It was bright rust brown breasts and red berries against a backdrop of snow.
