Aquatic warbler  (Acrocephalus paludicola)

The aquatic warbler is more secretive than its common relative, the sedge warbler, and often remains hidden on the ground whilst actively searching for food. Similar to the other warblers, the aquatic warbler feeds primarily on small insects (3).

During the breeding season, males attract mates with a song produced during a short song-flight. A single male will normally mate with more than one female; mating amongst birds is usually a very brief affair, but for the aquatic warbler however, it can last around 25 minutes, taking place both before and after egg-laying. Nests are constructed from reeds and tend to be placed over marshy ground or in a clump of sedge in shallow water (4).
