Paddyfield Warbler

The Paddyfield Warbler, Acrocephalus agricola, is a small passerine bird belonging to the family Acrocephalidae. It is a modestly adorned species, with an unstreaked pale brown back and buff underparts, and a warm brown rump. A distinctive whitish supercilium graces its face above the eye. The bird measures approximately 13 cm in length, with a wingspan ranging from 15 to 17.5 cm.

Identification Tips

When identifying the Paddyfield Warbler, look for its short and pointed bill, which is shorter than that of the Eurasian Reed Warbler. The wingspan is also slightly less expansive. Both sexes appear identical, which is common among warblers, and the juveniles present with a richer buff on the underparts.

Habitat

This species thrives in low vegetation areas, such as long grass, reeds, and notably, rice fields, which provide both cover and feeding opportunities.

Distribution

The Paddyfield Warbler breeds in the temperate central Palearctic and is known for its migratory habits, wintering in the regions of Bangladesh, India, and Pakistan. While it is a rare vagrant to western Europe, there are small breeding populations along the western shores of the Black Sea, near the border between Bulgaria and Romania.

Behaviour

The Paddyfield Warbler lays a clutch of 4–5 eggs in a nest artfully concealed in grass. Its behavior is typical of warblers, actively flitting through vegetation in search of sustenance.

Song & Calls

The vocalizations of the Paddyfield Warbler are a delightful mix of fast-paced notes, much like the Marsh Warbler, with an array of mimicry and the characteristic acrocephaline whistles. Its song, however, is weaker and more rhythmic than that of its relatives.

Breeding

During the breeding season, the Paddyfield Warbler constructs its nest in grass, where it lays 4–5 eggs, continuing the cycle of life.

Similar Species

The Eurasian Reed Warbler is a similar species, but can be distinguished by its longer bill and wingspan.

Diet and Feeding

An insectivorous bird, the Paddyfield Warbler forages through vegetation, gleaning insects to fuel its active lifestyle.

Conservation status

The Paddyfield Warbler is currently listed as Least Concern on the IUCN Red List, indicating that, for now, this species is not at immediate risk of decline.
