Tooth-billed Hummingbird
Androdon aequatorialis
A distinctive, fairly large hummingbird with a super long bill. Note the streaky throat and breast, and dull green upperparts with a coppery crown. The tail has a pale gray base, a broad black band, and white tips. Sexes similar, although female lacks toothlike serrations on bill (nearly impossible to see in the field). Found in lowlands and foothills from extreme eastern Panama to northwest Ecuador. Typically occurs within mature humid forest where it feeds in the lower to middle levels.
Identification
The tooth-billed hummingbird has a total length of c. .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);clip-path:polygon(0px 0px,0px 0px,0px 0px);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}14 cm (5+1⁄2 in), which includes the long, essentially straight bill of c. 4 cm (1+1⁄2 in). Its common name refers to the small tooth-like serrations on the inner part of the distal half of the bill. It is shiny green above with a coppery crown. The underparts are whitish streaked dusky. The rounded tail is greyish with a broad black subterminal band and white tips. There is a conspicuous white band on the rump. In males, the bill has a small hook at the tip and more prominent tooth-like spikes; their plumage color averages brighter overall than females. While the green upper parts of this species are iridescent, its plumage is duller than that of most hummingbirds. Within its range, it is essentially unmistakable by the combination of the long, almost straight bill and the dark-streaked whitish underparts.
Taxonomy
The tooth-billed hummingbird's taxonomic position has been controversial, with some arguing that it should be placed in the subfamily Phaethornithinae, and others that it, together with the two lancebills, should be placed in their own small subfamily, Doryferinae. Today most authorities place it at the beginning of Trochilinae.

Range and habitat
The tooth-billed hummingbird is restricted to humid primary forests and nearby second growth. It occurs up to an altitude of c. 1,560 m (5,120 ft). In Ecuador, it is most frequent between 400–800 m (1,300–2,600 ft), while it mainly occurs between 600–1,560 m (1,970–5,120 ft) in Panama, and up to 1,050 m (3,440 ft) in Colombia.

Burchell's Starling
Lamprotornis australis
A large, long-tailed, iridescent blue-green to purple glossy starling with barred wings, and a round-tipped tail. Pairs, groups, and small flocks are resident in dry savanna, especially near thorn trees, where they have become common in camps and often associate with humans. The species feeds on the ground, walking with long strides and sitting low in trees, searching for insects, small vertebrates, and plant matter to eat. The similar Meves’s Starling differs from Burchell’s Starling by being bluer and smaller, with a more strongly graduated tail that is proportionately longer.
Comoro Thrush
Turdus bewsheri
A typical thrush in shape and size, but with unusual brown coloration. Varies significantly across the three islands where it occurs, and these populations may be full species. The Grand Comoro birds have plain pale brown underparts, the Moheli birds have darker blotching below, and the distinctive Anjouan birds are scaled on the underparts. Found in humid forest, secondary habitats, and plantations, mostly at higher elevations, though down to sea level in some places. The song is a typical thrush mix of whistles and quavering notes, whose exact structure varies on the different islands. Also gives “pik” notes, short trills, and a high-pitched “seet.”
Yellow-shouldered Grassquit
Loxipasser anoxanthus
A small seed-eating species of forest edges, open woodlands, and nearby weedy areas; usually found in groups of two to five birds. Both sexes have bright yellow-green shoulders and a buff vent, which are diagnostic but can be difficult to see. Otherwise, the Black-faced Grassquit is rather similar, but can be distinguished by its slimmer bill and duller back. Furthermore, male Yellow-shouldered Grassquits have an entirely black head, whereas black is limited to the face on the Black-faced Grassquit. The song is a series of four or five high-pitched buzzy notes that either rising or dropping in pitch, followed by one to three notes at another different pitch.
