Black-bellied Whistling Duck (Dendrocygna autumnalis)
Everybody knows ducks quack. Right? Well . . . yeah, sure. But not ALL ducks. Some ducks whistle, believe it or not, and since one of them, the black-bellied whistling duck, is a favorite of mine, that's the one we'll be talking about--and listening to--today.
Black-bellied whistling ducks were called Black-bellied TREE ducks back in the Dark Ages when I first started birding. The name made sense to me, because you so often saw this large, long-legged duck perched in trees, especially along tall, dead limbs that afforded the duck a great view in all directions. I'm not sure if that's why they liked those so much, but that's where they were often spotted. But some time ago, their "official" common name (which is an oxymoron, by the way, since common names are not official, and are often different from place to place) got changed to Black-bellied whistling duck. Unlike many of the other seemingly arbitrary name changes in ornithology, this one actually makes sense. As mentioned above, this bird whistles instead of quacking. If you can't imagine such a thing, go HERE to check it our for yourself. (But come right back. We have lots more to learn about this guy).
