Blackish Nightjar
Nyctipolus nigrescens
A fairly small, dark nightjar found in the lowlands and foothills of northern South America. Intricately patterned with dark browns and grays; lacks any obvious features like a collar (although it sometimes shows a small white patch on the side of the neck). Males have small white corners on the tail. Almost always found at a landslide or rocky slope at the forest edge or in clearings, singly or in pairs. Most often detected at dawn and dusk, when it gives a burry “peer!” song and “pip” calls.
Identification
The blackish nightjar is 19.5 to 21.5 cm (7.7 to 8.5 in) long and weighs 32 to 39 g (1.1 to 1.4 oz). Its upperparts are blackish brown with tawny, grayish white, and cinnamon spots. Its tail is dark brown with indistinct lighter bars and mottling and (on the male) a white tip. The underparts to the belly are dark brown with paler baring; the belly and flanks are buffy with darker barring. The throat has a small white patch on either side. In flight the wing shows a small white band.
Taxonomy
The blackish nightjar was originally placed in genus Caprimulgus, but DNA analyses show that it and its sister species pygmy nightjar (Nyctipolus hirundinaceus) require their own genus. The blackish nightjar is monotypic.

Range and habitat
The blackish nightjar is found east of the Andes in Peru, Ecuador, and southern Colombia, and across southern Colombia through southern Venezuela and the Guianas into northeastern and north-central Brazil. They inhabit lowland evergreen forest, but are mostly found on or near open rock outcroppings or on sand and gravel bars along small rivers. In elevation it ranges from sea level in Brazil to 900 m (3,000 ft) in Bolivia, 800 m (2,600 ft) in Colombia, 1,200 m (3,900 ft) in Ecuador, and 1,100 m (3,600 ft) in Venezuela.

Yellow-crowned Euphonia
Euphonia luteicapilla
Small finchlike bird, compact and short tailed. Generally yellow below and dark blue-black above with stout, short bill. To identify male euphonias, focus on crown and throat: Yellow-crowned has an entirely yellow crown and a dark throat. Females extremely difficult to separate from other euphonias but often seen in pairs or small groups with males. Frequents open forested habitats, edges, and gardens. Can form mixed feeding flocks with other species such as warblers and tanagers.

Long-billed Cuckoo
Chalcites megarhynchus
A little-known cuckoo from lowland rainforest. Slender with long, thin bill that droops at tip. Males have dark cap, and red eye and eye-ring. Females have grey head and dark bill. Perches upright and motionless in sub-canopy. Voice a whistled, 2-note call with short first note, followed by loud descending note, “pu piiuuu!”. Similar to Tawny-breasted Honeyeater, but Long-billed Cuckoo is much less active with barring on the undertail. From Dwarf Koel by lack of white face mark and longer, thinner bill

Delicate Prinia
Prinia lepida
Tiny, disproportionately long-tailed, active, and vocal. The upperparts are gray-brown with heavy dark streaking, the underparts are pale, and each tail feather shows both pale and dark tips. Generally found in rather moist habitats within arid zones, including field margins, riparian woodland, scrub, gardens, and wetlands; can be quite numerous. Very vocal, especially in spring. The song is a rattling series of dry chirps, subtly different from the slower-paced song of Graceful Prinia. Males often sing from obvious perches. Visually extremely similar to Graceful Prinia, but there is little overlap in range. In any areas of overlap, best separated by song, but Delicate is also slightly longer- and narrower-tailed and browner.
