Celeus spectabilis obrieni
Uruçui, Piauí, Brazil.
Until recently, known from only single female specimen and treated as subspecies of C. spectabilis, albeit recognizing that its significant differences in plumage, habitat and geographical location indicated possible species status. This status now confirmed with discovery of birds in CE Brazil#R, which differ from taxa under C. spectabilis in having lower breast to vent (and underwing-coverts) clear pale dull yellowish-buff vs extensively mottled and barred black on yellowish-buff (breast-line is sharply defined sooty-black to yellowish-buff, but there are a few spots of black below this, and more concealed in breast feathers) (3); nape, mantle and wing-coverts predominantly pale dull yellowish-buff (slightly paler, less orangey, than below), with broad dark barring on wing-coverts (but still with more pale than dark coloration) and a few marks on scapulars and tertials vs heavily barred black on yellow-buff, the black greatly predominating, with tertials dull chestnut (3); tertials pale dull rufous-tinged yellowish-buff vs dull chestnut as on secondaries (2); back to uppertail-coverts orangey yellowish-buff, but paler and less orangey than in spectabilis (ns); bill appears more deeply and more extensively yellowish distally, although this could be individual variation (ns); smaller (at least 1). Full species status supported also by recent molecular studies#R#R, which indicate that obrieni is sister to C. spectabilis. Monotypic.
