Waking up each morning to the beautiful song of the Willow Warbler again, and having heard both this and the Chiffchaff singing on nearby Parkwood Springs I thought it was time to revisit these beautiful, elusive and similar-looking spring migrants. Chiffchaff arrive mid-March and Willow Warbler, migrating further, arrive in April. This difference in migration journeys also explains one of the visual differences, with Chiffchaffs having shorter wings and Willow Warblers, flying further, having longer primary feathers/wing length. Chiffchaff have dark legs while Willow Warblers have pale pinkish legs and a brighter eye-stripe. Since they are hard to see, the easiest way to tell them apart is by song- Chiffchaff singing a two note eponymous song, and Willow Warblers have a lovely long song ending with a downward trill. The BTO have a great little on-line video on telling them apart. (The photo’s of the Willow Warbler are from our garden, the Chiffchaff from Spurn).
