Doug originally entered this as a probable Blue-winged Teal X Northern Shoveler hybrid. This was based in part on a bird that was studied on several occasions during the winters of 2008-2009 and 2009-2010. That bird was seen on a half-dozen or more occasions (including Burris Basin, and along the upper SAR, at Kraemer Basin and at Anaheim Lake), and showed a number of similarities to this current one. If not for the more than 10 years between these two occurrences I might have assumed they were the same individual. Based on features that were studied (and documented in photos), the previous hybrid was considered a Blue-winged X Northern Shoveler (and I had positive feedback from others with at least some hybrid waterfowl experience on that earlier bird). As it turned out, however, there were some important differences between the two presumed hybrids (which were first noticed by Tom Wurster and Kiandra Mitchell), by review of photos of apparently known hybrid combinations. In the following description, some differences are mentioned between the presumed BWTE X NSHO from over a decade ago, and this particular (probable) CITE X NSHO (though if no comparison is mentioned, the details apply to the current bird here at Burris Basin). The bird appeared to be an adult male. Green sheen on head, similar to Northern Shoveler (though in some light angles the head appeared to show a dull blue-gray sheen similar to that of a male Blue-winged Teal; this blue-gray color mainly seemed to be noticed towards the "face", while the side of the head generally seemed to show the more dominant green sheen). The head also showed very bold, clean white facial crescents, which seemed identical--in prominence and position--to that of a male BWTE. The bird showed bright rusty sides/flanks (similar to an adult male NSHO, and of course CITE as well). The breast, however, was duller than the sides (a somewhat paler, rusty-buff). The BWTE X NSHO from a decade ago showed a substantially paler breast in comparison to the sides. Another difference between the probable BWTE X NSHO and this probable CITE X NSHO was that the previous hybrid showed fine, dark speckling and chevrons on the breast and sides, whereas this current (2021) bird does NOT appear to show any fine markings on the sides/flanks or breast. The rear flanks always looked clean white on the alleged BWTE X NSHO, while oddly enough more of a buffy-white on the bird's left side, and a cleaner white on the right side of the current hybrid. The dark undertail coverts were jet black looking on the BWTE X NSHO, and perhaps more of a dull black on this presumed CITE X NSHO. The bill size/shape was not seen well, as the bird was constantly foraging, with the bill tip always submerged in the water. The eye appeared golden-yellow, similar to that of a male Northern Shoveler (on the previous hybrid the eye was described as "fairly dark"). The legs were not seen well on the recent hybrid, though from at least one photo appear orangish at their base. Pin is where the duck was observed; we viewed it from the trail opposite, to the west.
