Media notes
White-crested phenotype. The dominant male in a family group of one female and four males. One of the other family males was white-crested (shown in the second photo), another black-crested, and I can't remember the third male.
Observation details
Number estimated. The golf course population has an unusually high percentage of white-crested birds, approximately 30-40% of males; in forested areas nearby, white-crested birds are virtually absent, with black- and dark gray-crested birds universal. On the golf course white-crested and black-crested birds can be found in the same family groups. This phenotype matches the White-crested race, L. l. hamiltoni, which besides the white crest shows a distinctly scaled back, more broadly white-tipped rump plumage, pearly white breast, and pinkish legs. These features in black-crested birds (matching the Nepalese nominate race) are an evenly gun-metal blue-black back, narrowly white-tipped rump plumage, breast sooty grey, and legs blackish.
