Your article about joy-riding pigeons (“Gravy-Trained,” 7/30) was in error when it said: “The downside of auto-loving birds becomes clear as a car barrels down the road, crunching a pigeon in the middle of the street with a wet pop. Other birds hurry over to pick at the greasy remains of their former kin. They continue to feast as another car rolls directly above them.”

Unlike most other birds, pigeons are vegetarians. They do not cannibalize each other. They probably dash over the same way we humans would if a friend we hung out with every day got hit by a car: very concerned, frightened, wanting to help, finding out how bad the situation is, trying to revive or comfort their dead or injured friends. Pigeons mate for life, bond strongly, and they mourn.
