Sorry for the shaky video; I will try to upload an image-stabilized version soon, but I am worried that the image-stabilization might blur some the details.

Update 2023-11-07: It’s a barnyard-type (non-standard-bred) female Rouen (Mallard-derived domestic breed). Looked at my copy of the American Standard of Perfection by the American Poultry Association one day, because I knew I had seen that face pattern somewhere before, and it hit me. D’oh! 🤦♀️ Caveat: clouds, time of day, and distance affecting lighting and views of details. General size and shape of Mallard, but appearing darker brown than female Mallard (not having Mallards at hand to compare, it at least appeared darker than nearby female Northern Shovelers). Larger than nearby Northern Shovelers. Bill seemed olive in color, like eclipse/immature male Mallard. Strong dark-and-tan face pattern reminiscent of Pacific Black Duck but not quite as contrasting (tan supercilium, dark eyeline, tan patch below lores and eye, dark malar stripe sweeping up and appearing to join eyeline below/just behind eye, tan throat). Ruling out Pacific Black Duck, however, is the speculum, which appeared to be blue, bordered by white on both leading and trailing edges like Mallard, not green with no white borders as on Pacific Black Duck. Could this be a Mallard x Pacific Black Duck hybrid? Seems “out there” given that there are no eBird records of either Pacific Black Duck or Mallard x Pacific Black Duck hybrids in North America. Just a weird Mallard? Some kind of domestic variant I don’t know about (I was involved in the standard-bred poultry scene for some time but I don’t recall seeing a strong face pattern like this on a Mallard-derived domestic breed)? A variant or hybrid of a wild Mallard-like species that would be more expected here in Colorado - Mexican, American Black, Mottled Duck (I am not familiar enough with any of these)? Crummy digiscope photos and video. Sorry for the shaky video; I will try to upload an image-stabilized version soon, but I am worried that the image-stabilization might blur some of the details. The bird spent a good amount of time foraging among the cattails (and thus hidden) near 40.1006706, -105.1863181; I was viewing from not far down the short trail from the open space parking lot off of Niwot Rd.
