Common Reed-warbler

The Common Reed-warbler (<em>Acrocephalus scirpaceus</em>) is a member of the family Acrocephalidae and is one of the most familiar wetland warblers across its range. It inhabits coastal and wetland environments, strongly associated with tall phragmites reed beds bordering lakes, rivers, and marshes. Detailed plumage and behavioral descriptions of this species are limited in the available literature. It constructs a deep cup nest (CP) woven around reed stems, and lays 3 to 5 eggs per clutch. Incubation lasts approximately 8 to 13 days, one of the shorter ranges in the genus, with chicks fledging within 9 to 13 days. The Common Reed-warbler is assessed as Least Concern, with a broad breeding range across Europe and western Asia. It is a well-known host of the Common Cuckoo, which parasitizes its nests. This ecological relationship has made it a subject of considerable scientific study on brood parasitism and host-parasite coevolution.
