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