Plain Gerygone

Male has dark slaty-gray head, neck, and upper breast; rest of the body is pale gray, with white on the belly. Wings darker than mantle. Female lacks the black hood, and has a whitish supercilium, brownish-gray upperparts with lightly barred back and rump, and buff-white underparts with wide brown bars. Juvenile is similar to female, but upperparts barred white. Immature similar to female. Song is a series of clear, loud whistles: “pee-pe-pe-pe-pe-twe-twee.” Some notes can be omitted, or additional notes added. 

Small scops-owl with bright yellow eyes, found only on Simeulue. Almost uniformly rufous-brown, with very inconspicuous (often flattened) ear tufts. The only resident scops-owl on Simeulue; migrant Oriental Scops-Owls could also occur on the island, but average larger, and have a more well-defined facial disc. Utilizes a variety of wooded habitats, from pristine forests to plantations. Listen for its song, a series of hiccupy piping notes, somewhat reminiscent of a barbet. Also gives a series of short squeals, which are sometimes mixed in with the song.

Tiny hummingbird endemic to western Ecuador. Male has a violet throat, a green “vest” on otherwise white underparts, white spots on either side of the rump, and a thin, forked tail. Female lacks throat patch and has a rusty tinge to underparts, a black stripe through her face, and a shorter tail. Inhabits deciduous and semi-humid forest, especially in hilly areas near the coast. Undertakes seasonal movements that are not well understood, and is occasionally seen farther inland.
