Intrabrood variation in nestling mass among three sagebrush-associated songbirds
Ashleigh M. Rhea, Jason D. Carlisle, Anna D. Chalfoun
2022, The Wilson Journal of Ornithology (134) 345-351
The young of some altricial bird species hatch asynchronously, which can lead to considerable size differences among siblings. Nestling traits such as body mass, moreover, can carry over and influence post-fledging survival. Despite the potential importance of nestling mass for reproductive outcomes, however, variation in nestling mass and...
