Hi you'll, It ain't easy being a Black-bellied Whistling Duck and trying to raise a family in real life. Last year we had a pair of BBWD's with 12 ducklings. By the end of the season there was one parent duck and one duckling surviving. Illness,gators, herons, egrets, & ospreys take a harsh and rapid toll on them. This year we had two parents with 24 ducklings 3 weeks ago. As of this week the parents and only 9 ducklings survive.
