Five Instances Of Bird Mimicry Suggested For Neotropical Birds: A Brief Reappraisal [cinco Exemplos De Mimetismo Propostos Para Aves Neotropicais: Uma Breve Reavaliação]

Examples of mimicry among birds are rare worldwide and the Neotropics are no exception. Five cases of mimetic associations suggested for Neotropical birds are here reappraised. 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. The sets Cathartes aura-Buteo albonotatus and Ramphastos tucanus-R. vitellinus seem to have good functional evidences. The first case would qualify as aggressive mimicry, and the second one would qualify as foraging mimicry. 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. However, the set Chondrohierax uncinatus-falconid and accipitrid species remains without adequate functional evidences. The resemblance in the plumage pattern and the partial habitat overlap of this latter set indicate mimicry as well, plausibly of the aggressive type.184328335Amadon, D., Relationships of the falconiform genus (1961) Harpagus.
