Great Reed Warbler

Acrocephalus arundinaceus

LC · Least Concern

Identification

A large brown warbler with a strong bill, pale eyebrow and a powerful, rough song. Its heavy build distinguishes it from the smaller Eurasian Reed Warbler.

When to look

A migratory breeding bird in Romania. European birds spend the non-breeding season in sub-Saharan Africa; arrival and departure vary with weather.

Where to look

Tall, robust reeds beside open fresh or brackish water provide feeding cover and nesting supports. Reed edges are more promising than completely open lakes.

Behaviour and ecology

Food and nutrition

Mostly insects and other small invertebrates, collected among reeds. It can occasionally take small vertebrates, and some fruit outside the breeding season.

Breeding and life cycle

The deep cup is woven around several reed stems above water. Retaining uncut reed patches and suitable water levels helps preserve this nesting habitat.

A closer look

Its nest is anchored to several flexible stems, so it moves with the surrounding reeds instead of depending on a rigid branch.

Global conservation assessment

LC · Least Concern

Global category recorded from the linked assessment; it does not describe local abundance. Least Concern does not mean absence of threats.

Observation and photography

Listen first and wait beside an established route. A singing male may climb into view; do not push into reeds or use playback.

Sources and further reading

Keep a distance that allows birds to feed and rest normally. Do not enter colonies, approach nests, flush roosts or use playback for photographs. Never publish precise nest locations of sensitive species. Follow reserve rules and your guide's advice.
