The bright yellow underparts are what initially caught my attention. On looking
at the bird, I immediately noticed the very narrow white eye-ring. It took two
or three careful looks to
verify that it was indeed narrowly broken in front and back. This, and the sight hooded affect, brought MacGillivray's to mind, but I immediately dismissed this as everything about the bird seemed wrong for MacGillivray's. Rather, the feeling was I was looking at something I'd never
seen before. Further observation just solidified this belief.
