Black-cheeked Warbler

Males are striking with a mostly glossy black body, but with a red forehead, crest, and back. Females are uniformly olive-green and also crested. Locally common in gallery forests embedded in savannas where it often accompanies mixed-species flocks. The song is a trilling series of alternately soft and loud whistles.

A large dark-brown pigeon with faint pale speckles on its plumage. In flight, shows chestnut wing panels, and flies with a loud clattering of wings. Found only on the sandstone area of Arnhem Land in the Northern Territory, where it can be encountered at locations throughout Kakadu National Park and beyond. Often roosts on high rocky cliffs or on top of sandstone towers; comes down to the sandy ground in the early morning and evening.

Small, mouse-like bird found in cloud forest understory in Colombia’s Santa Marta Mountains. Adult male is gray with a white crown patch and rusty barring on the lower underparts. Female is washed with brown, and young birds have a lot of scaling and barring. The only other tapaculo in the Santa Martas is Brown-rumped Tapaculo, which lacks white in the crown, occurs at higher elevations, and has a different voice. Typical song is a very fast trill that lasts for at least ten seconds and may continue for a minute or more.
