I do not know for sure if this is a Black-Bellied Whistling Duck or a Mexican Squealer. They are in the same family, sort of like cousins I think and there are some subtle differences between them. Both of them can roost in trees, perch on high lines and they do not “honk” like most ducks, they make a kind of whistling sound. They are pretty colored ducks. We see them all over our part of Texas.
