Seasonal drivers of mixed-species flocks from tropical savannas: insights from the Pantanal wetland

Autor: Gilberto Josimar Fernández-Arellano, Juliana Bonanomi, Joao B Pinho

Publikováno v: Journal of Field Ornithology, Vol 94, Iss 3, p 3 (2023)

Birds participate in different types of multi-species groups (e.g., mixed-species flocks) occurring from temperate to tropical forest and also savannas. However, the effects of seasonal variation in flocking dynamics and formation in tropical savanna

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 94, Iss 4 (2022)

Abstract Acoustic communication plays a key role in the life of birds and it is useful in phylogenetic and evolutionary investigations. This study described the structure and function of Polioptila dumicola´s call repertoire in riparian environments

Foraging preferences of the threatened coastal California Gnatcatcher (Polioptila californica) during the non-breeding season

Autor: Kevin B. Clark, Kimberly Ferree, Kylie Fischer, Stephen J. Myers

Publikováno v: Journal of Field Ornithology, Vol 94, Iss 2, p 6 (2023)

We studied the foraging behavior of the federally threatened coastal California Gnatcatcher (Polioptila californica), an obligate insectivore, during the non-breeding season, a period of reduced survivorship for this non-migratory passerine due to se
