March 27, 2016 – Cinereous Mourner chick (Laniocera hypopyrra)

Requested by: coramatus

Found in northeastern to central South America, these birds in the Tityridae family also have an isolated population in eastern coastal Brazil. They feed on arthropods and fruit, foraging alone or sometimes joining mixed-species flocks. Their cup-shaped nests are constructed from dry leaves. The chicks have fuzzy, bright orange plumage that mimics the appearance of the toxic caterpillars of flannel moths (in the Megalopygidae family). The nestlings also sway slightly when disturbed, copying the movements of the caterpillars. These adaptations likely protect the chicks by deterring predators.
