You might remember this photo from a short while ago where I thought it was a Chiffchaff, but as I’d never heard it’s distinctive “Chiffchaff” song I was in debate whether it was it’s almost identical Willow Warbler.
Early this morning, not too long after sunrise, I finally heard, for the first time that easily identifiable call of the Chiffchaff.
