You can tell my age because I call these birds Tree-Ducks. (Don't be surprised when I say a Northern Harrier is a Marsh Hawk.) These ducks nest in tree cavities and nest boxes. They form life-long pairs. Often they lay eggs in other whistling-duck nests (Dale and Thompson 2001). With so many whistling-ducks nearby, we had no trouble hearing their loud, whistled "pe-che-che-ne" calls.
During our Texas travels, we looked in vain for the other North American whistling-duck, the Fulvous. We read reports on eBird of south Texas Fulvous Whistling-Duck sightings, but the ducks kept a step ahead of us.
