Creamy-bellied Gnatcatcher
Polioptila lactea
Distinctive gnatcatcher. Males have a glossy black cap and are gray above with a white face and yellow-washed underparts. Females have a gray cap. Forages acrobatically in the canopy and at the edges of humid forests and woodlands. May be seen alone or with mixed-species flocks. The song is a fast, thin “weet-weet-weet-weet.”
Identification
The creamy-bellied gnatcatcher is 10 to 12 cm (3.9 to 4.7 in) long and weighs approximately 7 g (0.25 oz). The male has a bluish-black cap and white lores and supercilium. Its upperparts are dark slate blue. Its long tail's central feathers are black and the outermost white with those between being black and white. Its cheeks and underparts are pale yellowish transitioning to white on the lower belly. The female and juvenile are similar to the male but with slate gray crowns.
Taxonomy
The creamy-bellied gnatcatcher is monotypic. It has occasionally been thought to be conspecific with the tropical gnatcatcher (P. plumbea).

Range and habitat
The creamy-bellied gnatcatcher is found in southern Brazil from Mato Grosso do Sul and Rio de Janeiro states south to Santa Catarina state and adjoining southeastern Paraguay and northeastern Argentina. It inhabits several biomes including open humid forest and its edges, temperate rainforest, semi-deciduous forest, and scrublands. It elevation it usually occurs below 400 m (1,300 ft).

Behavior
The creamy-bellied gnatcatcher's diet is not well known but is probably small insects and spiders. It forages by gleaning and hover-gleaning foliage, alone and in mixed-species foraging flocks.<p>Almost nothing is known about the creamy-bellied gnatcatcher's breeding phenology. One nest has been described. It was built by both sexes of moss and leaves in the crotch of a branch near the top of a 30 m (98 ft) high tree.<p>The creamy-bellied gnatcatcher's song is "a simple, rather fast repetition...tee tee tee tee swee swee swee" [1]. Its call is spie [2].

Gray Tit
Melaniparus afer
A large gray-brown tit with a black-and-white head pattern and a black bib. Pairs and small groups favor dry coastal scrub and Karoo, particularly near rocky outcrops where nest holes are available. It forages for insects in small groups or mixed-species flocks. The song is typically a whistled “piet-tjou-tjou, tudi-tudi-tudi,” with scolding, buzzing, and chattering interspersed. The Ashy Tit is similar to the Gray Tit, but it is colder gray rather than buffy, with whitish wing edgings and a longer tail, and prefers Acacia thornveld habitat.
Black Guan
Chamaepetes unicolor
Large chickenlike bird found in montane forests. Entirely black plumage with blue facial skin, red eye, and reddish legs. Sexes similar. Unlikely to be confused: smaller and blacker than Crested Guan; lacks curled head feathers of Great Curassow; also found at higher elevations. Can be seen on the ground or in trees, usually in pairs or small family groups. Feeds on fruit.
White-fronted Plover
Anarhynchus marginatus
Plain, pale plover that is sandy on the back and white below. Preferred habitat is sandy beach, a habitat not favored by most other shorebirds, though also uses mudflats, riverbanks, and other wetlands. Generally common along the coast, and only occurs very locally inland. Smaller than sand-plovers in non-breeding plumage, with a white collar. Much smaller than Caspian Plover. Plainer face than Kittlitz’s Plover. Short, straight, thick plover bill separates White-fronted Plover from all sandpipers.
