. Bulletin of the British Ornithologists' Club. Northern Pintail x Chiloe Wigeon, male showing vermiculated flanks and suffusion of colour on upper breast which extends on to Dorsal view of hybrid showing well developed scapulars and tail feathers, and vermiculations of mantle and back. From the above details it can be seen that all the characters of the hybrid can be found in the males of the parental species. In fact the hybrid can be said to be intermediate between the parental species with perhaps slightly more Pintail than Chiloe Wigeon characters. The white face of the Chiloe Wigeon has gone, as have the breast vermiculations of that species. The bright russet colour of the flanks of the Chiloe Wigeon are replaced by black and grey vermiculations, but this colour, reduced to pale russet (mars brown of Ridgway), occurs on the upper breast, sides of breast and upper mantle of the hybrid. The metallic green stripes from eyes to nape that are characteristic of the Chiloe Wigeon are present and unchanged in the hybrid. The most noticeable Pintail characters are the well developed scapulars and tail feathers, and the vermiculations on the flanks and dorsal surface. In measurements the hybrid is much closer to the Pintail than to the Chiloe Wigeon. There are no characters in the morphology of the hybrid than can be said to be of phylogenetic significance.
