Potential Mottled Duck on canal w/ 4 Mallard. Photos.
Compared to rubripes, overall paler aspect to the plumage, with warmer tones, paler crown, and warm buffy unstreaked throat and chin. Yellow bill with prominent black spot at the gape also a pro-fulvigula feature. Did not get a good look at the spread wing, but paler more turquoise tone of the speculum at some angles looked different to either rubripes or platyrhynchos. Did not see the thin white trailing edge evident in photos taken by others. No obvious signs of hybridization with platyrhynchos, such as white in tail or curly black uppertail coverts. Hard not to conclude this is fulvigula.
w/ Bubulcus ibis, Egretta garzetta, Ardea cinerea
