Marsh Warbler (Acrocephalus palustris)

In common with all warblers, the marsh warbler is very active. It searches for its favourite invertebrate prey of small insects and spiders, which are picked from vegetation (2). This species arrives back in its British breeding grounds between late May and mid-June, much later than its relative the reed warbler (2), and pairs soon set about building their cup-shaped nests. The nest is built around plant stems close to the ground. One brood of 4-5 pale blue eggs is laid in May to early July (3) and both parents share the 12 day incubation duties (2).
