Yellow-crested helmetshrike

The yellow-crested helmetshrike (Prionops alberti) or King Albert's helmetshrike is a species of bird in the Vanga family Vangidae. This large, striking helmetshrike is unique in its black plumage and bright yellow crest. Though this species has been encountered broadly across the mountains of the eastern Democratic Republic of the Congo, there is still much to learn about this species. It is rarely reported due to the majority of its distribution occurring in relatively remote regions within the Albertine Rift, an area with ongoing armed conflict.

Adults are generally all black with a bright yellow or gold crest (sometimes described as a "helmet"), with the yellow extending across the entire top half of the head above the eyeline and extending backwards behind the eye. The greenish-yellow irides are surrounded by an orange eye-wattle; the bill, like the plumage, is black, though the legs and feet are reported to be light red. Individuals can be quite variable in terms of crest color, ranging from grayish-white to pale yellowish to bright gold, with variation possibly attributable either to individual variation or to wear. "Berlioz" (likely Jacques Berlioz) communicated that the yellow pigments in the crest feathers are "soluble in benzine, alcohol, and to some extent even in water". Some birds also have varying amount of gray or white in the webbing of the primaries, but some birds are wholly black.

Young birds have whitish crowns that appear dirty or faintly yellow. The bills of juveniles are likely light red, not black.

Sexually monomorphic.

The call has been described as a two-parted "tlu-uk" or "clu-uk" in the field, repeated as many as six times. Responds strongly to alarm calls from other individuals.
