Yellow-billed caciques are large song birds. The body is completely black in both males and females. Males, however, have a more lustrous shine to their feathers than females. Both sexes also have a characteristic beak which is a whitish-yellow color. Their eyes are vibrant yellow as well. They are different from other caciques in the fact that they are the only ones who are open-nest builders. That is, they build an open-topped, cup–shaped nest in which to lay their eggs. They range in size from 56.7 to 70.9 g and from 21.6 to 25.4 cm in length, males are slightly larger than females.
