A small insectivorous bird, the Chiffchaff is a small, 10–12 centimetres long leaf warbler. The spring adult has brown-washed dull green upperparts, off-white underparts becoming yellowish on the flanks, and a short whitish supercilium. It has dark legs, a fine dark bill, and short primary projection (extension of the flight feathers beyond the folded wing). This warbler gets its name from its simple distinctive song, a repetitive cheerful chiff-chaff.
