Features & Description
The Common Reed Warbler, Latin name Acrocephalus scirpaceus, is an insectivorous bird with a pointed head, rounded tail and long undercaudals, and a slender beak. It blends into its favorite environment. It has a pale, short, vague eyebrow that doesn’t reach the back of the eye.
The back is brown with vague shades of olive-gray, while the rump is reddish-brown.
Habitat (Biotope)
This bird lives in the reedbeds of ponds, preferably tall and bushy, but not necessarily extensive. It seeks its food in adjacent herbaceous areas, whether cultivated or not.
Behavior & habits
The Common Reed Warbler is a territorial bird, which explains its sonorous presence during spring and especially summer. The male sings, perched in full view in the upper part of the reeds, sometimes climbing up and then rapidly descending along the stem.
This bird feeds on arthropods, mainly insects found among the reeds, aquatic larvae and small spiders. On migration, it may also eat berries.
Reproduction and immature
The Common Reed Warbler breeds as soon as the female arrives on the male’s territory in late April or early May. The female is responsible for building the basket-shaped nest, while the male follows her, defending the territory against rivals. The nest, built in the reeds, can accommodate up to 5 spotted blue eggs. Up to 2 eggs may be laid per season. The Yellow Warbler is often parasitized by the Grey Cuckoo, which even imitates the color and shape of the eggs.
Cry or Voice
On contact, a brief, discreet “tché” is emitted. They tend to sing at dusk and dawn, with a quiet, chatty rhythm of high-pitched sounds repeated 2 or 3 times, occasionally with imitations or whistles.
