![]() ![]() Although predation of small vertebrates has been reported for this hawk species, the lizard P. ABSTRACT: We report the predation of the lizard Polychrus marmoratus (Squamata: Polychrotidae) by Buteo albonotatus (Accipitriformes: Accipitridae) in southeastern Brazil. Palavras-chave: Gavião-de-rabo-barrado, Lagarto, Dieta, Predador, História natural. Tal registro traz uma contribuição para a história natural de lagartos brasileiros. marmoratus não havia sido ainda registrado como sua presa. Apesar da predação de pequenos vertebrados já ter sido reportada para esta espécie de gavião, o lagarto P. Nós registramos a predação do lagarto Polychrus marmoratus (Squamata: Polychrotidae) por Buteo albonotatus (Accipitriformes: Accipitridae) no Espírito Santo, Brasil. RESUMO: (Predação de Polychrus marmoratus (Squamata: Polychrotidae) por Buteo albonotatus (Accipitriformes: Accipitridae) no sudeste do Brasil). The resemblance in the plumage pattern and the partial habitat overlap of this latter set indicate mimicry as well, plausibly of the aggressive type. However, the set Chondrohierax uncinatus-falconid and accipitrid species remains without adequate functional evidences. The functional evidences of the sets Accipiter bicolor-Harpagus diodon and Philydor rufus-Orchesticus abeillei are less evident than in the first two ones, but additional field studies may strengthen the suggested hypotheses. The first case would qualify as aggressive mimicry, and the second one would qualify as foraging mimicry. ![]() vitellinus seem to have good functional evidences. The sets Cathartes aura-Buteo albonotatus and Ramphastos tucanus-R. ![]() The sets Cathartes aura-Buteo albonotatus (Cathartidae and Accipitridae), Ramphastos tucanus-Ramphastos vitellinus (Ramphastidae), Accipiter bicolor-Harpagus diodon (Accipitridae), Philydor rufus-Orchesticus abeillei (Furnariidae and Thraupidae), as well as Chondrohierax uncinatus (Accipitridae) and a subset of falconid and accipitrid raptors are illustrated and field and literature data are presented. Five cases of mimetic associations suggested for Neotropical birds are here reappraised. Examples of mimicry among birds are rare worldwide and the Neotropics are no exception. ![]()
