First recorded
In a location you monitor regularly (at least once a week), record the first time you see a live, active chiffchaff.
Chiffchaffs are a summer visitor, arriving from March to April - your observations can help determine the date at which they first arrive for summer. Chiffchaffs are increasingly overwintering particularly in southern England, if observed throughout winter please select recorded all winter.
