  This small tyrant flycatcher has a disjunct distribution across South American grasslands. It is recorded in low grassland with scattered scrub near water.

• Parrot-billed Seedeater Sporophila peruviana

  This small seed-eater occurs along the Pacific lowlands of western Ecuador and Peru. Its unusually large, thick bill is a clear feature.

• Short-crested Flycatcher Myiarchus ferox

  This flycatcher forages in river-created habitats and other second growth in Amazonia. Its gray breast changes sharply to a yellow belly.

• Rusty Flowerpiercer Diglossa sittoides

  This Andean bird feeds on nectar. Its hooked bill is used to pierce flowers and reach the nectar, as described in the regional guide.

• Brown-breasted Bamboo Tyrant Hemitriccus obsoletus

  One individual was documented in a bamboo patch in Misiones, northeastern Argentina. The description here follows that local observation.

• Nightingale Finch Nesospiza questi

  A finch of Nightingale Island in Tristan da Cunha. A breeding study records females building nests in dense grass tussocks.

• Rufous-crowned Tody-Flycatcher Poecilotriccus ruficeps

  This tiny flycatcher, about 9.5 cm long, has a rufous crown, pale cheeks edged in black and a yellow underside. It searches for insects in the understorey of humid montane forest and tall second growth.
