Eurasian Reed Warbler

The Common Reed Warbler, Acrocephalus scirpaceus, is a medium-sized warbler measuring approximately 13 cm in length with a wingspan ranging from 17 to 21 cm. It exhibits an unstreaked brown back with buff underparts. Both sexes are identical in appearance, which is typical for warblers. Juveniles can be distinguished by their richer buff underparts. The species is characterized by a flattened forehead and a robust, pointed bill.

Identification Tips

When identifying the Common Reed Warbler, look for its brown, unstreaked back and buff underparts. The bird's supercilium is less pronounced than that of the larger Great Reed Warbler. In flight, observe the wing-span and listen for its distinctive song.

Habitat

This species is almost exclusively found in reed beds, often with interspersed bushes, providing it with the necessary cover and nesting sites.

Distribution

The Common Reed Warbler breeds across Europe into the temperate western Palaearctic and is migratory, wintering in sub-Saharan Africa. It is also a resident species in large parts of Africa.

Behaviour

Males typically arrive at breeding grounds a few weeks before females. The species is generally monogamous, with pairs raising up to two broods per season. It is known to be brood parasitized by the Common Cuckoo.

Song & Calls

The song of the Common Reed Warbler is a distinctive slow, chattering "jit-jit-jit" with acrocephaline whistles and mimicry.

Breeding

Nests are built by the female over water, often in reeds, and are deep cylindrical cups. Clutches usually contain three to five pale green eggs with olive or grey speckles. Both parents incubate the eggs, which hatch after 9-12 days. Fledglings leave the nest after 10-12 days but are fed by parents for an additional 10-14 days.

Similar Species

The Great Reed Warbler is similar in appearance but is larger and has a more pronounced supercilium.

Diet and Feeding

The Common Reed Warbler is primarily insectivorous but may occasionally consume plant material such as berries.

Conservation Status

The IUCN lists the Common Reed Warbler as Least Concern, indicating a stable population.
