Seychelles Bulbul
Hypsipetes crassirostris
A medium-sized gray bird with a black cap and a carrot-colored bill. Endemic to the granitic Seychelles. Found in virtually all habitats with a woody component, including forest, woodland, scrub, villages, and plantations. Often in small, noisy groups. The song is an unmusical series of rattling and scraping notes, often given from a high perch. The calls include a “chek” note and a long, whining call.

行为
The Seychelles bulbul is social, living in pairs, family groups or small flocks in forest and woodland from the sea to the granitic mountains. The Seychelles bulbul is monogamous and territorial in the breeding season. The territory is about 200 m (660 ft) in diameter. It is defended against other bulbuls and potential predators with loud alarm calls, and even large intruders, including man, can be mobbed. A helper, probably a previous offspring, is tolerated but not allowed to approach the nest.<p>The breeding season of this bird usually begins at the start of the monsoon, around October to January, although breeding can occur at any time. It builds a circular nest out of palm fibres, leaves, twigs and moss in a forked tree branch, usually 10 m or more above the ground. Two whitish eggs with spots are usually laid per season, although in most cases only one chick is successfully raised to fledging age. Incubation lasts for 15 days and fledging occurs 21 days after hatching, but young fledglings will accompany adults after fledging, possibly to learn foraging skills.<p>The species is omnivorous, taking fruit, flowers, eggs, and insects gleaned from foliage or hawked during short flights. They are very aggressive towards other bird species, chasing away birds as large as green-backed herons from areas in which they are feeding.

West African Seedeater
Crithagra canicapilla
A medium-sized brown seedeater. Note the boldly marked face with a dark crown, a white eyebrow, and a broad dark-brown patch through the eye. The underparts lack streaking, but may show some brown blotching. Found in woodland, scrub, and cultivated areas. Often in pairs or small flocks. Similar to Reichard's Seedeater, but there is little overlap in range, and West African is easily separated by the unstreaked underparts. Somewhat similar to White-rumped Seedeater, but lacks a white rump, and has a strong facial pattern and unstreaked underparts. Gives a pretty, musical up-and-down song of whistles and trills which also sometimes includes imitations of other birds.
Dusky Eagle-Owl
Ketupa coromanda
A very large, grayish-brown owl with yellow eyes and distinctive ears. Note the fine barring and dark streaks on the pale underparts, and white patches on the shoulders. In flight, wings and tail are strongly barred below. Perches in tall trees, usually near a water body, where it waits for birds and mammals to pounce upon. The call is a distinctive series of low, guttural notes that increase in volume and speed before trailing off towards the end.
Marsh Tapaculo
Scytalopus iraiensis
Small, dark ash-gray tapaculo. Note the unbarred dark brown vent. Occurs in marshy areas with dense tall grasses and sedges, where usually devilishly difficult to see. The song is a long (c. 30 seconds) repetition of “tchek” notes.
