Yellow-crowned night-heron Nyctanassa violacea

Identification Tips:




Similar species:

Adult unmistakable. Immatures separated from American Bittern by pale spotting on the upperwing, reddish eye, lack of black neck spot, different shape, stouter bills and more even upperwing coloration in flight. Juvenile separated from juvenile Black-crowned Night-Heron by pale edgings on greater secondary coverts, smaller spots about head and neck, larger bill and longer legs. Immatures can show a variety of plumage characters so are best separated from immature Black-crowns by their larger, thicker bill and longer legs, although if remnants of juvenile plumage or the first hints of adult plumage can be seen, the identification should be simplified.
