Warblers of the Reed

Most magnificient birds of world - reed warblers

Acrocephalus arundinaceus

General description: 

 A medium-sized bird and is the largest of the European warblers


The Great reed warblers favor reed beds as their habitat during breeding months, while living in reed beds, bush thickets, rice fields, and forest clearings during the winter. It breeds in Europe and westernmost temperate Asia. The females lay 3–6 eggs in a basket nest in reeds. Some pairs of warblers are monogamous, but others are not, and unpaired, territory-less males still father some young

Conservation status: 

The Great reed warblers is a common and widespread bird, and it considered a species of least concern by the IUCN


The Great reed warblers has a primarily carnivorous diet. Observation of prey collection specifically during breeding season has shown the retrieval of insect larvae, moths, dragonflies, damselflies, beetles, spiders, small fish, and frogs. Male great reed warblers have been observed to communicate via two basic song types: short songs about one second in length with few syllables, and long songs of about four seconds that have more syllables and are louder than the short variety. It has been observed that long songs are primarily used by males to attract females; long songs are only given spontaneously by unpaired males, and cease with the arrival of a female. Short songs, however, are primarily used in territorial encounters with rival males.


It measures 16–21 cm (6.3–8.3 in) in length, 25 to 30 cm (9.8 to 11.8 in) in wingspan and weighs 22 to 38 g (0.78 to 1.34 oz). The adult has unstreaked brown upperparts and dull buffish-white chin and underparts. The forehead is flattened, and the bill is strong and pointed. It looks very much like a giant Eurasian reed warbler (A. scirpaceus), but with a stronger supercilium.

While there are no subspecies of this bird, mtDNA haplotype data indicate that during the last glacial period there were two allopatric populations of the great reed warbler. Acrocephalus arundinaceus in southwestern and southeastern Europe were at that time apparently separated by theVistulian-Würm ice sheets and the rrounding barren lands.


The great reed warbler breeds in Europe and westernmost temperate Asia. It does not breed in Great Britain, but is a regular visitor. Its population has in recent decades increased around the eastern Baltic Sea, while it has become rarer at the western end of its range. It is a migratory bird, wintering in tropical Africa. This bird migrates north at a rather late date, and some birds remain in their winter quarters until the end of April.


On their breeding grounds, the great reed warbler they are territorial


The great reed warbler is found in large reed beds, often with some bushes.
