Resumo: | Habitat loss and fragmentation is recognized as one of the main causes of global biodiversity declines. Birds of prey are considered good environmental bioindicators because they are sensitive to changes in the environment and can suffer local extinctions due to habitat fragmentation. In this study, we aimed to determine whether forest fragment area is correlated with the richness and abundance of owl species, and whether owl species recorded exhibit preferences for fragment edge or interior. The study was undertaken in six remnants of southeastern Atlantic Forest located in Minas Gerais State, Brazil. Six species of owls were recorded: Buff-fronted Owl (Aegolius harrisii), Tropical Screech-Owl (Megascops choliba), Tawny-browed Owl (Pulsatrix koeniswaldiana), Striped Owl (Asio clamator), Mottled Owl (Strix virgata), and Rusty-barred Owl (Strix hylophila). Megascops choliba was the most abundant species. The richness and abundance of species were higher at the edge when compared to the interior of the fragments. The owl species recorded did not seem to prefer the forest interior, while M. choliba had a preference for forest edges. This study adds new empirical knowledge on the effects of fragmentation on Neotropical owl communities. |

Las aves de presa se consideran un buen bioindicador ambiental porque son sensibles a los cambios en el medio ambiente y pueden extinguirse localmente con la fragmentación del bosque. El objetivo del estudio fue responder a las siguientes preguntas: ¿La fragmentación de los bosques influyen en la riqueza y abundancia de las especies de búhos? ¿Las especies de búho tienen preferencia por el borde o el interior de los fragmentos del bosque? El estudio se llevó a cabo de octubre de 2011 a septiembre de 2012 en seis localidades de la Mata Atlántica suroriental, ubicadas en el estado de Minas Gerais, Brasil. Seis especies de búhos fueron registradas: Lechucita Acanelada (Aegolius harrisii), Currucutú Común (Megascops choliba), Lechuzón Mocho Chico (Pulsatrix koeniswaldiana), Búho Gritón (Asio clamator), Mocho Carijó (Strix virgata) y Rusty-barred Owl (Strix hylophila). M. choliba fue la especie más abundante. La riqueza y abundancia de especies fue mayor en el borde comparado con el interior de los fragmentos. La comunidad de búhos en nuestra área de estudio no parece tener preferencia por el interior del bosque, sin embargo, M. choliba es más abundante en los bordes del bosque. Este estudio aporta nuevos conocimientos sobre la riqueza y abundancia de los búhos neotropicales y su respuesta a la fragmentación de la Mata Atlántica.This journal Ornitología Neotropical permits and encourages authors to post items submitted to the journal on personal websites or institutional repositories both prior to and after publication, while providing bibliographic details that credit, if applicable, its publication in the journal Ornitología Neotropicals.
