Chiffchaffs and Willow Warblers are hard to tell apart and both might be stopping off in your garden, like the Chiffchaff is in ours, filling up on their way south for winter migration. If you get the right view, you can see that Chiffchaff’s have dark legs, and, migrating shorter distances, have shorter wings. Willow Warblers have pale pinky-orange legs, are usually more yellow in overall colour, and have longer wings for longer migration. The photo’s should help!
