Named for its ragged patch of head feathers resembling gray hair in alternate plumage, the diminutive Ancient Murrelet has a black head and bib, partial white collar, gray back, straw-yellow bill, and white underparts. In winter, the white head streaks fade and the black bib is encroached by white. At a distance, the contrasting gray back separates Ancient from other murrelets and alcids.
