Black-bellied Whistling-Duck

On 22 February, after we left Santa Ana National Wildlife Refuge and headed out towards Estero Llano State Park. Along the way we searched for Fulvous Whistling-Ducks, but all we found was a solitary Black-bellied Whistling-Duck. This odd duck appeared to have been asleep in a cultivated field.

In North America, this species breeds along the coasts of Mexico and in Southern Texas. The species’ range is expanding in the United States. Unlike birds further south, most, but obviously not all, of these ducks migrate to Mexico. As I have posted before, Black-bellied Whistling-Ducks form life-long pair bonds but often lay their eggs in their neighbors' nests.
