Brown-headed Honeyeater

Glossy small black cuckoo with a forked tail. Juvenile has a galaxy-like smattering of white spots all over the body. Square-tailed Drongo-Cuckoo has a less prominently-forked tail; note less difference in length of outermost tail feathers. Adults may be confused with drongos, but are lighter-billed and smaller, with distinctly white-barred undertail. Widespread, found in forests and scrubby plains from lowlands up into foothills and mountainous areas, but much more often heard than seen, typically sitting still in the middle and upper levels of forest; song is an extremely loud ascending series of whistles. Lays its eggs in the nests of babblers, bulbuls, and shrikes.

A fairly small rail, mostly gray below and olive-brown above with bicolored bill (red base, yellow tip) and pinkish legs. Black and white barring on vent can be difficult to see. Shy and typically uncommon to rare. Most often found in dense marshy habitats, including flooded rice fields and pastures. However, not necessarily tied to water, and can also be found in moist forest with dense understory. Even its vocalizations aren’t well-known, but makes a low, fast, cooing trill.

Chunky, stout-billed bird of humid evergreen forest and edge in tropical lowlands. Occurs from throughout much of the Amazon basin (east of the Andes). Usually found in pairs, often skulking at low to middle levels in lush vegetation. In typical views, looks simply dark. Note the very stout bill and broad tail, which can be twitched side to side. Male is deep blue-black overall. Female is rich dark brown overall. Sharp squeaky call often doubled and rather distinctive.
