From the author: Observations of parental feeding roles were made at 19 Yellow-breasted Chat (Icteria virens) nests during the 1994 breeding season in central Kentucky. Male and female chats fed nestlings at similar rates, and adult feeding rates were unaffected by brood size. The absence of any change in feeding rates with increased brood size suggests that food requirements per nestling decrease as brood size increases, perhaps because of differences in thermoregulatory costs. In contrast to the results of many other studies, provisioning rates and load sizes (number of prey delivered per visit) did not increase with nestling age. However, our observations at chat nests did not begin until nestlings were 3 or 4 days old. Studies of other species have revealed that 1-3 day old nestlings may be visited less frequently and provided with smaller loads than older nestlings, and observations of nestling chats during this early period might have revealed similar behavior.
