• American Grey Flycatcher Empidonax wrightii

  This small flycatcher lives in dry highland shrublands and open woods, where it waits for insects from a perch. Its slow downward tail dip helps distinguish it from similar flycatchers.

• Yellow-bridled Finch Melanodera xanthogramma

  This finch inhabits Andean rocky ground and high-altitude grassland. Males are yellow and olive, while females and young birds are brown and streaked; it searches for seeds on the ground.

• Black Jacobin Florisuga fusca

• Rufous-headed Pygmy Tyrant Pseudotriccus ruficeps

  The Rufous-headed Pygmy Tyrant was recorded in the understory of Colombia’s western Andes. At La Linda, observers heard a few individuals daily and captured an adult male in dense Chusquea bamboo.

• White-bridled Finch Melanodera melanodera

  The White-bridled Finch forages on the ground in the grasslands of Magallanes and has conspicuous yellow wings.

• Ash-throated Casiornis Casiornis fuscus

  A rufous flycatcher of Brazil. Its breeding habitat differs from the open woodland and savannas used by migrants outside the breeding period.

• Collared Warbling Finch Poospiza hispaniolensis

  The Collared Warbling Finch occurs in Ecuador and Peru. Males show a white eyebrow and breast band, while females are browner and have dark streaks on the breast and belly.

• Smoky-fronted Tody-Flycatcher Poecilotriccus fumifrons

  A tiny, roughly 9 cm tyrant flycatcher. It forages inconspicuously in low bushes, and pendant pouch-like nests have been recorded in French Guiana.

• Small Ground Finch Geospiza fuliginosa

  The Small Ground Finch is endemic to the Galápagos Islands and eats seeds, fruit, and small arthropods. An 1841 account describes the female’s underparts as gray.

• Spectacled Tyrant Hymenops perspicillatus

  This tyrant flycatcher lives in South American grasslands and wetlands. Males are black with yellow around the eyes and on the bill. Breeding has been studied in native tall grassland in the Argentine Pampas.

• Seven-colored Tanager Tangara fastuosa

  This tanager has noticeable violet and orange plumage. It eats fruit and arthropods and also uses forest edges and gardens.

• Golden-crowned Flycatcher Myiodynastes chrysocephalus

  This flycatcher inhabits humid Andean montane forest. Its yellow crown patch can be concealed, while a broad white eyebrow and streaked yellow underparts are conspicuous.

• Giant Conebill Conirostrum binghami

  In Peru, this conebill is strongly associated with Polylepis woodland. It has a long, pointed bill.

• Crowned Chat-Tyrant Silvicultrix frontalis

• Pale-throated Pampa-Finch Embernagra longicauda

  A highland grassland bird of eastern Brazil that searches among rocks and shrubs for food.

• Buff-banded Tyrannulet Mecocerculus hellmayri

  This tyrannulet occurs on the eastern Andean slope in south-eastern Peru and Bolivia. It uses the canopy and subcanopy of humid mountain forest, alone, in pairs, or in mixed flocks.

• Slate-colored Seedeater Sporophila schistacea

  Males range from dark gray to gray-olive. The species occurs around humid forest edges and understory, and may move in search of seeding bamboo, though it is not an obligate bamboo specialist.

• Little Ground Tyrant Syrtidicola fluviatilis

  The Little Ground Tyrant is a small flycatcher of broad river beaches and mudflats. In 2014, one bird was recorded on a sandbar of the Napo River in Ecuador; the paper considered it a non-breeding visitor.

• Chestnut-vented Conebill Conirostrum speciosum

  The male has a gray-blue back and chestnut vent and is found in forest canopy and along forest edges. Females have different brown and olive tones.

• Northern Scrub Flycatcher Sublegatus arenarum

  This small flycatcher ranges from Central America into northern South America. It uses mangroves, nearby vegetation, and scrubby second growth while searching for food.

• Chestnut-bellied Flowerpiercer Diglossa gloriosissima

  This flowerpiercer lives in montane forest and high shrubland in Colombia's Western Andes. It feeds on nectar and also takes insects.
