| Because anis have altricial nestlings, the provisioning help of all breeding adults is essential. |
| Territorial males sired the majority of offspring, but residents and transients also sired small numbers of nestlings. |
| The number of food deliveries made to supplemented and control nestlings were counted from the observation blind. |
| Carrion Crow nests are conspicuous and we were able to observe birds delivering food to nestlings using spotting scopes. |
| All nestlings were banded, which enabled a study of recruitment to the breeding population. |
| We wondered what would happen if a female lost her eggs or nestlings to predators and began the nesting cycle anew. |
