The Black-bellied Whistling Duck is an elegant duck that is a resident in the US only in parts of Texas and Florida. From there, it ranges south to central South America. It gets its name from its call, a hoarse whistling song which I heard a ton from this one as it flew back and forth.
The duck hung out in one spot for a while, at times being joined by a few foraging Mallards, and then three Green Herons. The last visitor it had at this spot was a less friendly one, a young Peregrine Falcon that dove out of nowhere to within a few feet of it, testing his luck at a much larger meal than he's used to. The falcon flew away empty handed. It took me a little while to relocate the duck, who had actually only moved about twenty feet. After a bit, he was spooked again and took off flying to the end of the dike and then back to another spot where he began to forage and where I got a couple of decent pictures.
Another cool bird I saw was a very trusting juvenile Virginia Rail that was in the open about fifteen feet from me when I first noticed it. That makes two lifers in one day. I also managed my first decent Great Egret shot.
