Describe la biología reproductiva del ave endémica Geositta peruviana, “Minero peruano” en la Zona Reservada Lomas de Ancón, departamento de Lima, Perú. Se tomaron datos de aspectos reproductivos: periodo reproductivo (incubación y periodo de polluelos dentro del nido), características de nidos, éxito reproductivo, cuidado parental y distribución de nidos. Para obtener estos datos, se realizaron visitas mensuales al área de estudio entre noviembre del 2016 y noviembre del 2017, en búsqueda de actividad reproductiva. Se utilizaron dos cámaras sonda de tres y cinco metros de longitud para inspeccionar los nidos y evaluar el número de huevos y polluelos, siendo más frecuente la inspección durante la temporada reproductiva. Se desenterraron cuatro nidos abandonados para describir su contenido. La temporada reproductiva se extendió de mayo a octubre, coincidiendo con la ép...

Th e Villa Wetland, located in Lima, Peru, hosts a remarkable diversity of fauna, with a particular emphasis on avifauna. Th e reproduction of birds is a crucial element in the natural history of these species, making studies essential to guide conservation and management strategies for both bird populations and the ecosystems they inhabit. Th e objective of this study was to characterize and evaluate reproductive aspects of the Gray-hooded Gull [Chro icocephalus cirrocephalus (Vieollot 1818)] and the Black-headed Hen [Cora gyps atratus (Bechstein, 1793)], such as the biometry of nests, eggs and reproductive behavior. Nest monitoring was carried out between the months of May to September 2023. For C. cirrocephalus, 12 nests were found in patches of “sweet grass” Paspalum vaginatum Sw.; while, for C. atratus, four nests were recorded at the base of “molle costeño” Schinus terebin...

Birds are an important group in the fauna of the wetland of the Pantanos de Villa Wildlife Refuge, Lima, Peru. Th e Passeriformes that are specialists in this wetland, such as Wren-like rushbird [Phleocryptes melanops (Vieillot, 1817)] and the Many-colored rush tyrant [Tachuris rubrigastra (Vieillot, 1817)], make their nests in the wetland vegetation. Th erefore, its reproduction and its relationship with vegetation were studied in this research. Nests of both species were searched between May to October 2022 in the Génesis lagoon, and in the Mayor Lagoon. A description of the reproductive behavior in incubation, chicks, and reproductive success, etc. was made. In the vegetation, data were taken such as the height of the vegetation, the vegetation cover, the measurements of the nest, height of the nest, number of leaves that support the nest, among others. While, for parental behavior, ...
