This is a gallinaceous bird, typical of the Gran Chaco area - and well-known there, as it is considered by many to have delicious meat. The ethnographer and zoologist Erland Nordenskiöld once called it "forest chicken", which is quite fitting. It is a medium-sized bird, about 50 cm long, weighing clearly less than one kilo. It is mainly gray-brown and lacks a cockscomb, but has two red wattles under the chin. It subsists on berries, buds, and leaves, but also on insects during certain periods. It is often heard in the morning with a sound that has given it its Spanish name "Cha-ra-ta". We spotted this individual far away, but could approach it with the car without disturbing it. I slipped out on the back of the car and put the lens on the car roof and got this picture. The bird seemed a little worried, but it did not fly away. It was still in the tree as we continued. (It was my first close-up of a chachalaca).
