Scaly-breasted Thrasher
Allenia fusca
A drab-colored and inconspicuous species typically found from the middle level to the canopy in woodlands, where it mostly feeds on fruits. This species can be distinguished from similarly shaped and colored Pearly-eyed Thrasher by its short dark bill and barred, not streaked, underparts. Song is a deliberate series of high-pitched squeaks and lower-pitched whistles. Most common call is a high, thin whistle.
Identification
The scaly-breasted thrasher is approximately 23 cm (9.1 in) long and weighs 53 to 98 g (1.9 to 3.5 oz) with an average weight of 67 g (2.4 oz). With its rather short and slightly decurved bill, this thrasher resembles a thrush. Adults of the nominate subspecies have a dark gray-brown head and upperparts with a reddish tinge on the rump. Their tail is a darker brownish black and its outer feathers have white tips. The folded wing shows a single white bar. Their chin and throat are whitish with brown streaks. The underparts are whitish and the chest and flanks have bold gray-brown markings that give the eponymous scaly appearance.<p>The other subspecies differ mostly in size and the intensity of their upperparts' color. A. f. hypenema is the largest and is paler than the nominate. A. f. schwartzi is mid-sized and has more white on its tail. A. f. vincenti is the smallest and is darker overall than the nominate. A. f. atlantica compared to the nominate is more reddish brown above and has less white in the tail.

Behavior
The scaly-breasted thrasher forages in trees; on different islands it hunts at different levels from low down to high in the canopy. It is omnivorous; its diet includes arthropods, fruits, and berries. It appears to eat a larger percentage of vegetable foods than other thrashers.<p>The scaly-breasted thrasher breeds in May and June. It builds a cup nest in a bush or tree. The clutch size is two or three.<p>The scaly-breasted thrasher's song is a "[s]eries of varied notes and phrases" similar to that of Mimus mockingbirds but softer and slower.

Comoro Pigeon
Columba pollenii
Big, dark pigeon with black-and-white slashes on the back of the head. The feet, bill, and eye-ring are bright yellow, but the bird looks plain in flight. Found on the Comoro Islands in the canopy of moist forest, secondary habitat, and plantations. Most common at higher elevations. Common vocalization is a growling call, followed by several low hoots. Could be mistaken for Madagascar Turtle-Dove, but dwells in the canopy, is larger, has yellow bare parts, and doesn’t show pale corners to the tail in flight.
Spot-tailed Antwren
Herpsilochmus sticturus
Small antbird of rainforest canopy; somewhat more common in forests with sandy soils. From below, note clean white underparts and heavy bill. Usually encountered with mixed-species flocks. Forages slowly along limbs and explores leaf clusters. Very similar to Todd’s Antwren and most safely separated from that species by voice. Song is an accelerating “bouncing ball” series, similar to Pygmy Antwren but with a harder quality and not falling in pitch at the end.
Socotra Cormorant
Phalacrocorax nigrogularis
Medium-sized, slender black cormorant. Note diagnostic white plume tuft on the cheeks (most noticeable in breeding adults). Juvenile is dull brown with paler underparts. Breeds on small desert islands in the Persian Gulf and Arabian Sea. Exclusively coastal, shunning inland waters. Forages in flocks, often in immense congregations.
