THE AQUATIC WARBLER. 



{Acrocephalus aquaticus.) 



' I 'HE genus Acrocephalus embraces all the 

 -*■ species which we call "Sedge" Warblers, 

 and "Reed" Warblers, and which belong to the 

 little group of old World SylviidcB, to which 

 allusion has been made in the previous article. 

 Like all the other members of the genus, the 

 Aquatic Warbler — a badly chosen name to dis- 

 tinguish it by, as all Acrocephali are aquatic or 

 water-haunting birds — is a migrant, and the only 

 time when I have ever met with it in the wild 

 state, was in the island of Heligoland, when I 

 accompanied Mr. Seebohm and Mr. F. Nicholson 

 on their excursion to this interesting locality 

 in 1876.
