prydmaurfugl Myrmoderus ferrugineus

Beautiful medium-sized antbird of rainforest floor; most common in tall primary forest. Note rich rusty coloration, bright blue eyering, and habit of walking on ground; throat is black in males and white in females. Flips leaf litter and probes into crevices in logs, often jumping up onto fallen trees and walking along them. Distinctive song is musical and carries far. Can be difficult to see; scolding rattle is usually the first indication that one is nearby.
