Horned screamers are related to geese, and they are definitely loud. They are also called donkey birds. Though I can hear the resemblance of their sounds to donkeys, screamers make distinctive and quite frankly beautiful sounds. It is a wondrous experience to hear them off in the distance while floating down a tributary of the amazon. They are wary of humans and always fly off when one gets too close, making a good image tough to obtain. "Anhima cornuta", Peru.
