Sex roles in nest keeping - how information asymmetry contributes to parent-offspring co-adaptation.

Co‐variation between parental response in provisioning and offspring begging behavior When not taking the number of individually experienced begging playbacks into account, the begging intensity of genetic nestlings appeared to be marginally significant (model 4, F 1,38.0 = 4.263; P = 0.046, Table 2 ), but this relationship did not differ between parents (model 4, F 1,37.0 = 0.168; P = 0.685, Table 2 ).
