Abstract:The Crested Black-Tyrant (Knipolegus lophotes) is a member of the Tyrannidae family that occurs throughout open areas in central, southeastern and southern Brazil. Although this species occurs in regions that surround the state of Mato Grosso do Sul, there had never been a recorded sighting in the state. Thus, information on its distribution across Brazil's midwestern region is scarce. In this study, we report the first sightings of K. lophotes in Mato Grosso do Sul. These records extend the known distribution range of the species in midwestern Brazil and contribute to expanding knowledge of bird species composition in this region. We believe that the absence of K. lophotes from the lists of bird species recorded in different localities in Mato Grosso do Sul may be a reflection of its local rarity and the lack of bird inventory efforts in this region, which underscores the need for further research into bird communities in this poorly known region of Brazil.

Primeiros registros da maria-preta-de-penacho (Knipolegus lophotes, Tyrannidae) no estado de Mato Grosso do Sul, Brasil. Biota Neotrop. 12(3): http://www.biotaneotropica.org.br/v12n3/pt/abstract?shortcommunication+bn01012032012Resumo: A Maria-Preta-de-Penacho (Knipolegus lophotes) é um membro da família Tyrannidae que no Brasil ocorre em áreas abertas das regiões sudeste, central e sul. Apesar de ocorrer em regiões próximas ao estado de Mato Grosso do Sul, a espécie nunca foi registrada neste estado, e assim informações sobre sua distribuição no centro-oeste do país são escassas. Neste artigo reportamos os primeiros registros da ocorrência de K. lophotes no Mato Grosso do Sul. Estes registros ampliam a área de distribuição conhecida dessa espécie na região centrooeste do Brasil e contribuem para o conhecimento da avifauna desta região. Acredita-se que o registro recente de K. lophotes no Mato Grosso do Sul se deva tanto a sua raridade local quanto a falta de estudos ornitológicos mais amplos no estado, apontando a necessidade da realização de mais estudos nesta região pouco conhecida do país em relação a sua avifauna. Palavras-chave: aves, Tyrannidae, extensão de distribuição geográfica, Cerrado, M.N. et al.

Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.
