Clamorous Reed Warbler

Acrocephalus stentoreus

Large brown reed warbler with a long, powerful-looking bill. Birds in the Middle East and northeastern Africa average warmer brown than in southern Asia. Most readily confused with other large reed warblers. Oriental Reed Warbler has a “rough-looking,” vaguely streaked throat unlike the clean throat of the Clamorous Reed Warbler. Worn birds may not be identifiable to species level, especially if seen poorly. Great Reed Warbler is similar, but has pink instead of gray legs. Breeds in a wide range of wetland habitats, including freshwater marshes, lakeshores, and mangroves; even in cultivation in some areas. Non-breeding habitats also include drier areas. Song is a loud and jumbled series of harsh grating sounds. Calls include loud, forceful, and hard-sounding chuck’s and churrs.

Identification

Clamorous reed warbler is a large song thrush-sized warbler at 18–20 cm. The adult has an unstreaked brown back and whitish underparts. The forehead is flattened, and the bill is strong and pointed. The sexes are identical, as with most warblers. It is very like the great reed warbler, but that species has richer coloured underparts.<p>There are a number of races differing in plumage shades. The migratory northern race has the richest brown upperparts, and the endemic Sri Lanka subspecies is the darkest form.<p>Like most warblers, the clamorous reed warbler is insectivorous, but will take other small prey items.<p>The song is loud and far-carrying, but less raucous than that of the great reed warbler. It is a slow, chattering kereet-kereet-kereet with typically acrocephaline whistles and mimicry added.

Other Birds

Amazonian Tyrannulet

Amazonian Tyrannulet

Inezia subflava

Small flycatcher with a long tail often held cocked. Has an olive-brown back, yellow underparts, and two white wingbars. Note the broad white eye-ring “spectacles”. Always found near water, for example in shrubby vegetation at lake edges, and especially on river islands. Forages in the understory. Sings an intermittent series of fast high “pit-chew” notes, often in a duet.

Bat Hawk

Bat Hawk

Macheiramphus alcinus

An acrobatic, swift-like raptor with angular wings and a massive gape; capable of snatching prey from the air and devouring it in a flash while still on the wing. Dark with varying amounts of white on the underside; African birds have patchy white throughout the underparts, while white is restricted to the throat and lower belly on New Guinean birds and solely to the throat in Southeast Asian birds. Inactive during the day; hunts at dawn and dusk, and occasionally into the night if light is sufficient. Generally uncommon and localized, most reliably encountered near large bat roosts in forested areas, but can also be seen over open forest, fields, and fringes of habitation.

Fox Sparrow

Fox Sparrow

Passerella iliaca

Large, dark sparrow with extensive geographic variation. Larger than Song Sparrow, and generally darker with thicker streaking. Four groups of subspecies: Red (only subspecies found in eastern U.S., but breeds to Alaska), Slate-colored (Rockies), Sooty (Pacific Northwest), Thick-billed (California). Habitat varies across range, but generally breeds in forests with thick understory, often with plenty of conifers. In winter, tends to occur in dense thickets. Forages mainly on the ground in search of seeds. Visits feeders.
