You are correct about the similarity between New Zealand Shoveler and a Northern Shoveler x Blue-Winged Teal. An excerpt from Waterfowl: an ID Guide reads: "Occasional wild hybrids between Northern Shoveler and Blue-Winged or Cinnamon Teals bear a remarkable resemblance to Australasian Shovelers, but are smaller and of course likely to be met with only in North America." However, there were some basic differences that led me to believe that this bird was a hybrid. The head color of the New Zealand Shoveler is a slate-gray, whereas my bird had the green head of a typical Northern Shoveler. The marks along the breast and sides of New Zealand Shoveler are small chevron-like marks, whereas my bird had small roundish spots like a Blue-Winged Teal. The ground color of the sides and breast of the New Zealand Shoveler is an orange/brown that continues from the sides onto the lower breast and fades to whitish on the upper breast, whereas my bird had a breast that was uniformly colored light brown/tan that suddenly changed to orange/brown on the sides at the point where it normally changes to this color on a typical Northern Shoveler. It is certainly helpful to have an ID guide to world birds of a particular family when trying to identify an unusual looking species. Based on the field mark differences stated above, I still believe that the bird I saw was a hybrid, although I can't say whether it was wild or an escaped captive. Mike
