Dartford warbler with cricket, Arne RSPB reserve


‘Old World’ warblers, unrelated to the New World warblers, some of which appear as rare vagrants in the UK. Many species throughout Europe, Africa, Asia and Australasia.

In the UK, warblers can be separated into several groups – leaf warblers (slender, greenish birds of woodland and scrub, with simple soft call notes), reed, bush and grasshopper warblers (browner birds that live in wet places) and the Old World warblers (generally more patterned birds of woods and bushy places with short, hard call notes). Most are migrants but two species (plus increasing numbers of two others) remain in the UK in winter.
