The Paddyfield Warbler (Acrocephalus agricola) is a small passerine bird that inhabits wetlands and rice fields in central and Eastern Europe, western and central Asia, and northern Africa during the breeding season. It is a migratory bird that winters in sub-Saharan Africa.
The Paddyfield Warbler measures approximately 11-13 cm in length and weighs around 10-15 g. The male and female are similar in appearance, with a brownish-grey upperparts and buff underparts. The head has a distinctive broad and flat crown with a dark central stripe. The feet and legs are pinkish-grey, and the bill is brown.
These birds are known for their unique vocalizations, which consist of a continuous, chattering mix of notes. The songs are usually high-pitched, and the trill is faster than that of other warblers. Their calls are a series of sharp “tik,” “tik”, “tik” sounds, which are often repeated and sound like a sewing machine.
The Paddyfield Warbler primarily feeds on invertebrates, such as insects and spiders, and occasionally eats fruits and seeds. They forage by searching among tall grasses and rice plants and hovering or gleaning insects from vegetation.
During breeding season, the Paddyfield Warbler builds its nest in dense grasses and reeds near wetlands or rice fields. The nests are woven with grass and plant stems and lined with feathers and other soft materials. The female typically lays 4-5 eggs, which are incubated for about 12-13 days. Both parents care for the young, feeding them insects until they fledge and leave the nest.
The Paddyfield Warbler is listed as a species of Least Concern by the International Union for Conservation of Nature (IUCN). Despite its widespread distribution and stable population, habitat loss and degradation, pesticide use in rice fields, and climate change may affect their population in the future. Conservation efforts are necessary to protect wetlands and rice fields and to promote sustainable agricultural practices to benefit this species and other wetland birds.
