Chamí Antpitta

Grallaria Alvarezi

Bird of the month - August

The Chamí Antpitta is now an endemic bird from the Western Andes of Colombia

Fairly small antpitta, typical antpitta shape: plump and short-tailed with long legs, rufous plumage. Shy and difficult to see, but perhaps not quite as shy as other antpittas. Stays on or near the ground in humid montane forest from 2,200–3,300 masl.

“[…] Species of Andean humid forest are distributed over relatively narrow elevational ranges that can extend for many hundreds of kilometers, providing ample opportunities for geographical isolation across elevational and habitat discontinuities. Such discontinuities are especially prevalent in Colombia, where the Andes split into 3 main cordilleras and where other isolated highlands, such as the Sierra Nevada de Santa Marta, are present, and in Peru, where large rivers, such as the Marañón, the Huallaga, and the Apurímac/Ene, form deep arid intermontane canyons that are physical, ecological, and climatic barriers to dispersal.

[…]As part of a comprehensive study of the systematics and evolution of the G. rufula complex, focusing primarily on investigations of genetics and vocalizations, we obtained DNA sequence data for 80 individuals from across the range of the complex, to assess the extent of genetic differentiation among morphologically differentiated populations (recognized species and subspecies), the extent of cryptic genetic differentiation, and the extent to which vocal differentiation in this complex matches genetic differentiation.”

Bird of the month - August

We see this antpitta almost every time we go to Lucia’s place in our tour in the highlands of Jardín. Lucia call it Linda and they answer by this name, which is a funny thing to see.

If you have been with us in this tour you would definitely remember how they follow us across the trail looking for worms, if not just email us to book your next tour to see this new endemic.
