Andaman Coucal
Centropus andamanensis
A large, pale-brown, ground-dwelling cuckoo with rusty wings and back. Skulks in bushes and low cover, where it moves clumsily as it searches for small invertebrates, small mammals, and birds to prey on. Like other coucals, it is a cuckoo that builds its own nest. Common throughout its range in gardens, groves, disturbed forests, paddyfields, etc. The song is a series of deep and resonant “hoop” notes.
Identification
It is a large coucal, with males being around 380–400 mm (12.6-15.7 inches) and females somewhat larger at 400–420 mm (15.7-16.5 inches) in length. Structurally, it closely resembles the greater coucal (Centropus sinensis), except that its plumage is a fawn brown as opposed to the black with bluish-purple sheen seen in C. sinensis. It has a chestnut rear mantle and wings and the head is pale tawny brown. The mantle and breast grade from pale to dark brown on the belly and vent. The iris is pale brown. The tail is a pale brown at the base and dark violet-brown towards the tip. The tail feathers have conspicuous black shafts. The juvenile shows slight barring on the body, especially on the underside.
Taxonomy
This species was first described as Centropus andamanensis (toponym after its distribution) by R.C. Tytler, although his notes were published by R.C. Beavan in 1867. Stuart Baker (1927) continued to treat it as a species but Ripley (1961) and Ali and Ripley (1969) included it as a subspecies of Centropus sinensis. This is justified by the treatment of another species with a brown form in the Kangean Islands, Centropus sinensis kangeangensis. Peters considered it doubtful as a subspecies and noted a structural resemblance to the Sri Lankan Centropus chlororhynchus. Rasmussen and Anderton (2005) consider it a valid species on the basis of distinct vocalization and also suggest elevation of the Kangean form and further study of Centropus sinensis.

Range and habitat
It is mainly found in the Andamans (at least South, North and associated islets) as well as on the nearby Coco Islands and Table Island, which belong to Myanmar. It is common in forests and in disturbed areas including gardens, forest and edge, mangroves, edges of paddy fields.
- Migration
- Resident species
Behavior
It breeds during the monsoon (May through July). The nest is made of twigs, grass and leaves and is placed well above the ground in a tree. The usual clutch is two or three.<p>The song is much like that of the greater coucal, consisting of a long series of very deep and resonant hoop notes. The notes however rise abruptly in pitch. It is also known to produce chuckling and grating calls.<p>Feeds on all kinds of insects, small frogs, crabs and lizards.

Other Birds
Rufous-capped Spinetail
Synallaxis ruficapilla
Medium-sized, long-tailed spinetail found in the understory of humid forests often accompanying mixed-species flocks. Note the yellowish eyebrow, contrasting with dark cheeks, a pale throat, and a richly rufous crown, wings, and tail. It is brownish on the back and buffy gray below. The song is very distinctive nasal series of “prrr” rattles followed by a squeaky “Dje,” such as “prrrDje-prrrDje.”
Azure Kingfisher
Ceyx azureus
Small bright blue and deep orange kingfisher. Almost always found above water. It patrols up and down waterways and rivers from perch to perch flying very fast, and only a few meters off the water, typically making a loud high pitched "seeeeeeeep" call. Sacred Kingfisher has similar orange-buff belly, but it is a much larger bird.
West Solomons Owl
Athene jacquinoti
A rather small orange-eyed owl with lightly spotted brown upperparts and paler underparts. Prefers well-developed forest, mainly in lowlands, but up to 1500 meters of elevation. Unlikely to overlap in range with any similar species. Vocal range poorly known, but a series of monotone “poop” or “chong” notes is regularly reported. Found from Bougainville, Buka, and Choiseul in the north to Florida Island in the south. Formerly lumped with Guadalcanal, Malaita, and Makira Owls under the name “Solomons Boobook.”
