Avian Parents Hard At Work

To appreciate the parental demands on birds, consider the feeding habits of a pair of American Robins with a nest full of young. Both parents feed their 3 – 4 nestlings, delivering 6 – 7 feedings an hour, each one to a single nestling. (Parents tend to arrive with food at a particular location on the nest rim, so there is much jockeying for a position near this spot on the part of the nestlings.) Each nestling gets 35-40 feedings per day. This amounts to almost half a pound of food delivered to the nest every day for the 13 days that young are in the nest. Even then, the parents’ work is not done, as they continue to feed their fledglings for up to three weeks after the young leave the nest.
