Fitness benefits of alternated chick provisioning in cooperatively breeding carrion crows
Journal of Animal Ecology, Volume 93, Issue 1, Page 95-108, January 2024.In birds, parents typically raise their offspring together and can be assisted by helpers. Here, we show that carrion crow carers that take turns in feeding the brood produce healthier nestlings than those that do not. The payoff of cooperation therefore depends on the degree of coordination of group members.

The Canadian Field-Naturalist, 2013 At nesting colonies of American White Pelicans (Pelecanus erythrorhynchos), many chicks die from siblicide, severe weather, and disease; this results in carcasses available for scavenging by conspecifics (i.e., indirect cannibalism). Indirect cannibalism has not been reported previously for this species.
