These black bellied whistling ducks were hanging out as usual in a private pond near to the Terry Hershey Trail and Buffalo Bayou in Houston. Piercing whistles show that they fully deserve their name. This is a popular spot for birds. Here they were joined by cormorants and then a snowy egret.
Sometimes you ‘see’ an image that is just a perfect colour combination. These black bellied whistling ducks were serenely progressing through the green covering on a lake in Terry Hershey Park, Houston, and almost immediately disappeared beneath the overhanging vegetation. I just managed to grab a couple of shots that weren’t too bad.
I particularly like this one, cropped, that I’ve included at higher resolution.
Wikipedia lists 8 variants of whistling duck, or tree duck, and suggests that they are not actually true ducks but “a subfamily, Dendrocygninae, of the duck, goose and swan family”. They do look sort of intermediate between duck and goose.
