Birdfinding.info   The Andean form of Common Gallinule is locally common in high-elevation lakes and wetlands in Peru, Bolivia, Chile, and Argentina, including popular tourist destinations such as Lake Titicaca and Lake Junín.  It is usually present at several locations near Cuzco, including Laguna de Huacarpay and Laguna Huasao.

“Altiplano Gallinule”

Gallinula galeata garmani

Central Andean plateau, in lakes and wetlands from north-central Peru to northern Chile and northwestern Argentina.

Identification

Appears nearly identical to the widespread “American Gallinule” distributed throughout the Americas, but larger and darker.

Blackish overall, usually slightly browner on the back and wings—but some individuals appear all-black, while others have distinctly paler, medium-brown wings.

Notably larger than lowland forms in bulk and in the wings, which measure about 30% longer than those of other subspecies.
