Primeiro registro documentado de Leucopternis melanops (Latham, 1790) (Aves: Accipitridae) no estado do Maranhão e atualização da distribuição geográfica da espécie no Brasil

The Black-faced hawk, Leucopternis melanops (Latham, 1790), is the representative of the genus with the greatest geographic distribution, being common on the northern bank of the Amazon River and with rare records on the southern bank (Acre, Amazonas, Mato Grosso, Para and Rondonia). On June 24, 2018, an individual of L. melanops was found in the municipality of Centro Novo do Maranhao, state of Maranhao, Brazil, within the limits of the Gurupi Biological Reserve, which is the first documented record for the state. This record, added to others, served to update the limits of the distribution of L. melanops in Brazil, in addition to highlighting the importance of the Gurupi mosaic in maintaining unusual species.
