How to identifyThe Chiffchaff is a small olive-brown warbler which flits through trees and shrubs, with a distinctive tail-wagging movement.
Chiffchaffs usually (though not always) have dark legs and a pale eye stripe. They're easily confused for the Willow Warbler which has pale legs and a yellow eye stripe. Listen for the song which gives it its name, no other warbler makes that Chiff-Chaffing tune.
Chiffchaffs eat insects, either picking them out from trees or snapping them up in flight.
