Mottled or American Black Duck, Burlington WTP, Kit Carson

[Doug Faulkner]

Hello all,

I photographed this duck at the Burlington WTP in Kit Carson (eBird hotspot) yesterday.  Unfortunately, these photos are all that I have.  I saw it with binoculars and snapped a few quick pictures. It flew away while I set up the scope.

Thoughts on an ID are appreciated.
