Mottled or American Black Duck x Mallard hybrid?
This adult male Mottled/Am. Black/hybrid was digiscoped at a small, cypress-studded cove of Poverty Point Reservoir off N. Dam Rd., ca. 0.4 mi. E of LA-17 (across from Black Bear Golf Club), ca. 4 mi. N of Delhi (Richland Parish) on 13 Jan 2011. The male, presumably paired with a pure female Mallard, was accompanying a small group of seemingly pure Mallards and a Northern Shoveler. At first, this individual appeared very Am. Black Duck-like, at least from a distance, but upon closer inspection the plumage just didn't match up. The plumage seemed a better fit for typical, darker W. Gulf coast _maculosa_ Mottled. Warmer tones overall and the typical v-shaped marks on interior flank feathers. However, not shown in these digiscoped photos was a purplish, not teal blue, iridescent speculum bordered by black, which to me, was reminiscent of AMBD and not MODU. What's more perplexing about this individual is the location in extreme ne. LA where both AMBD and MODU occur very rarely.
