Estudo anatômico de tratos e aptérios em gavião carijó (Rupornis magnirostris, Gmelin, 1788)

Abstract

In order to study descriptive and topographical tracts and apteria in roadside hawk (Rupornis magnirostris), (15 males and 15 females), donated after death by the Superintendency of the Brazilian Institute of Environment and Natural Resources - IBAMA located in Pernambuco, were used. The birds were established by subcutaneous, intramuscle or intracavitary of aqueous 10% formaldehyde and immersed in the same solution during 48 hours. Then, with the aid of surgical instruments, the feathers were cut close to the follicle, leaving 0.2 to 0.3 cm of rachis for better viewing and recording of treatment and aptérios. It was used as comparative morphology, the Gallus gallus specie. Through the results, the study showed that the treatment and apteria described represent the morphological pattern of the specie, yet anatomical variations has not been observed in thirty copies, even belonging to different order, the R. magnirostris morphological features similar to those of G. gallus, and the pterilosys R. magnirostris do not constitute an auxiliary tool for sexing, because the anatomical configuration of aptérios and treatment are the same for both sexes.
