one possible dresseri x borealis female, but also may have been pure borealis; seen mating with male dresseri; photos by MJI and CLW; frontal lobes narrow and short coming to dull point, but coloration, thought paler, was not as extreme as in other bird, and the head also looked a bit more dull cinnamon-brown, more like the surrounding S. m. dresseri; another seen later was similar but colored even more like dresseri. Both had nicely pointed bill processes, and the photographed bird below even had a longer and more rounded central lobe of feathering as compared to dresseri. Below photos by Marshall Iliff:
