Descripción :	Micrastur semitorquatus, popularly known as Collared Forest-Falcon is an inhabitant of the rainforests of the Neotropical Region. Studies on the cranial osteology are scarce in the literature. To increase the knowledge about the anatomy of this species its cranial osteology was described and compared with other species of birds of prey. Three specimens of M. semitorquatus were examined at the Bird Division of the osteological collection at the Smithsonian National Museum of Natural History (USNM), Washington, DC (USNM: 245788, USNM 013493 and USNM 289773). Although the relationship between the form of a structure and its function is not fully established, many of the adaptations of the skull of M. semitorquatus may be related to this lifestyle and behavior, such as narrowing of the interorbital width, the robustness of pila supranasalis coupled with the prokinesis of the skull, a process developed post-orbital, and palatine expansion. In addition, the cranial osteology of M. semitorquatus can provide useful characters for cladistic analysis, sustaining the hypothesis of phylogenetic relationships with other species of the same genus or the same family. Micrastur semitorquatus é popularmente conhecido como falcão-relógio, habitante dasflorestas da região Neotropical. Estudos sobre sua osteologia craniana são escassos na literatura.Procurou-se, neste trabalho, descrever sua osteologia craniana e, com base nesta descrição,comparar com outras espécies de aves de rapina, buscando ampliar o conhecimento sobre aanatomia dessa espécie. Foram utilizados três espécimes de M. semitorquatus, que fazem parteda coleção osteológica da Bird Division at the Smithsonian National Museum of Natural History(USNM), Washington, DC, EUA (USNM: 245788, USNM 013493 e USNM 289773). Apesar da relaçãoentre a forma de uma estrutura e sua função não seja completamente estabelecida, muitas dasadaptações do crânio de M. semitorquatus podem estar relacionadas aos seus hábitos de vidae comportamento, como o estreitamento da largura interorbital,; a robustez da pila supranasalaliado ao procinetismo do cranio; um desenvolvido processo pós-orbital, e a expansão do palatino.Além disso, a osteologia craniana de M. semitorquatus pode fornecer caracteres úteis à análisecladística, podendo sustentar hipóteses de relacionamento filogenético dessa espécie com outrasdo mesmo gênero ou da mesma família. Cranial osteology of Micrastur semitorquatusVieillot, 1817 (Falconiformes: Falconidae)Micrastur semitorquatus, popularly known as Collared Forest-Falcon is an inhabitant of the rainforestsof the Neotropical Region.
