Type: article
Abstract: The Streamer-tailed Tyrant (Gubernetes yetapa) is an exclusively neotropical bird, associated with wetlands and widely distributed in Brazil. This study aimed to fill gaps in knowledge about this species, especially regarding its reproductive biology. We monitor a population of G. yetapa with the aim of describing its reproductive behavior, nest characteristics, and territory use in a wetland in the state of Rio Grande do Sul. Our findings revealed that this wetland serves as an important breeding site, where the total home range of the species was 28.2 ha, significantly reduced to 3.37 ha during the breeding season. The nest described here contained three eggs, two of which hatched successfully. After leaving the nest, the young birds foraged independently before joining mixed flocks with other species of birds. This study sheds light on the breeding ecology of the species and highlights the importance of wetlands for its conservation.
