New records of Neotropic Cormorant (Nannopterum brasilianum) nesting at the Nahuel Huapi lake, Argentina
Abstract
During the 2024/2025 breeding season I recorded a small colony of Neotropic Cormorants nesting in a tree on an islet in the central area of the Nahuel Huapi lake, where the Kelp Gulls nest. I visited it three times, thus I observed the chicks’ growth. This record complements the previous two recorded at the lake and highlights the need for monitoring, considering little is known about the reproductive habits of the species in the area.
