The Imperial Shag (Phalacrocorax atriceps) in the Nahuel Huapi Lake (northwestern Patagonia, Argentina) : distribution, abundance, and potential threats from scavenging birds

Mostrar todas las versiones(3)

We describe the distribution and breeding abundance of the Imperial Shag (Phalacrocorax atriceps) in the northern portion of the Nahuel Huapi Lake (northwestern Patagonia, Argentina) during the 2006-2007 and 2007-2008 reproductive seasons. We recorded low population numbers and null breeding success...

Se describen la distribución y la abundancia del Cormorán Imperial (Phalacrocorax atriceps) en el norte del lago Nahuel Huapi (noroeste de la Patagonia, Argentina) durante las temporadas reproductivas 2006-2007 y 2007-2008. Se registraron abundancias bajas y un éxito reproductivo nulo en ambas temporadas. Se registraron ataques de aves carroñeras y la actividad reproductiva se vio bruscamente interrumpida. Futuros estudios deberían considerar la potencial amenaza de las aves carroñeras, subsidiadas por los basurales a cielo abierto, sobre este cormorán. Aves Argentinas.
