Abstract
- Filial cannibalism (cannibalistic infanticide) is a common strategy among raptors though rare among other groups of birds. We describe the first case of possible parental infanticide followed by cannibalism by an adult and nestmates of Red-legged Seriema (Cariama cristata) in a brood of 3 in the Cerrado (savanna-like) ecosystem. A 20 min video recording showed a possible parent killing and eviscerating 1 of its nestlings and subsequently feeding it to the other 2 nestmates. This new record of brood reduction for wild Cariamidae might be a common behavior in both species of the family and may increase food availability and survival of the larger nestlings.
