Editing Common chiffchaff (section)

===Feeding===
Like most Old World warblers, this small species is [[insectivore|insectivorous]], moving restlessly through foliage or briefly hovering. It has been recorded as taking [[insect]]s, mainly [[fly|flies]], from more than 50 families, along with other small and medium-sized invertebrates. It will take the eggs and [[larva]]e of [[lepidoptera|butterflies and moths]], particularly those of the [[winter moth]].{{sfn|Clement|1995|p=56}} The chiffchaff has been estimated to require about one-third of its weight in insects daily, and it feeds almost continuously in the autumn to put on extra fat as fuel for the long migration flight.{{sfn|Clement|1995|p=58}}
