The chiffchaff is about 11 centimetres long. Its feathers are grey-tinged brownish green above and off-white below, with yellow and buff on its throat and breast. It has dark legs and a pale patch over the eyes.
This migratory bird can be found in woodland and scrub across Europe and Asia. It winters around the Mediterranean and in Africa.
The chiffchaff takes its name from its simple, repetitive song. Its domed nest is built on the ground, hidden in dense, low vegetation. It feeds on insects and the larvae of butterflies and moths.
