The Gray-headed Chachalaca is a relatively big arboreal bird with mostly a brown body and gray head. Their diet consists mainly of fruits. At my parents´ home, up to ten arrive at the feeders where my parents place the papaya. Due to their size, they throw the papaya to the ground while eating, which does not help the toucans when they arrive. They are very loud, particularly when spooked by predators or humans, although not as loud as Brown Jays. They can be seen gliding from tall trees, one after another in rapid succession, relying on the uplift from air currents to avoid expending energy on batting their wings.
