The Chaco Chachalaca is a large guan recorded in northern Argentina's woods and forests. Argentina's SIB species page describes pairs or small flocks moving quickly through tree branches.
Argentina's SIB account describes a gray head and neck, olive-brown back, grayish ochre underparts, and cinnamon belly and rump. The legs are pink, and the outer tail feathers are reddish.
Chaco Chachalacas use seasonally flooded Pantanal gallery forests, eating flowers as well as fruit.
At Brazil’s Miranda River during April2000–March2002, flowers formed44.6% of feeding records and over half in the dry season. Groups of two to four fed on flowering trees for30–60 minutes.
Birds ate ripening Genipa fruit in pieces, and up to ten fed at a fruiting fig. Seasonal dietary flexibility may help them remain in gallery forest through the dry season.
An extinction-risk assessment has not been added yet.
Seasonal fruit and flower resources support use of Pantanal gallery forest. Conserving food-producing trees and forest habitat helps retain resources available through the dry season.
