Whistling Ducks are still very active on the CyFair college campus. It seems that I see them whenever I walk from building to building. If they're not flying overhead, whistling away, they're perched on the top of various posts and poles.
On my way out of work yesterday, I stopped for a minute at the retention ponds to see how the ducklings are getting along. Only four of them were visible, being led around the pond by a parent. They're growing up fast and their stripes have given way to plumage that is beginning to resemble that of the adult birds.
