Black-bellied Whistling-Duck (Dendrocygna autumnalis)
According to reports by the Houston Audubon Society, Black-bellied Whistling-Ducks have recently been expanding their range in Texas. They can frequently be found in and around neighborhood ponds and lakes to the north and west of the Houston area. I have seen them on several occasions this fall at Bear Creek Park and once up north in the Tomball area, usually in groups of two to four.
