Atlantic royal flycatcher  (Onychorhynchus swainsoni)

This large-billed flycatcher is known for its spectacular crest, which is vivid scarlet in males, yellow in females, and ornately decorated with splashes of black and steel-blue tips (2) (3). Although the crest usually lies flat, protruding from the rear of the head, when fully extended it forms a large and impressive, forward-facing fan (3). The vivid colour of the crest stands out against the uniformly brown plumage of the upperparts and dull-yellow underparts. By contrast, the rump and tail are a bright cinnamon colour, and a small, whitish patch marks the throat (2).
