Chiffchaff and Willow Warbler: Spot the Difference

Williow warbler in full songChiffchaffs and willow warblers have been back in the country for a while now, and are singing their little heads off… which is a good thing… because the song is the most reliable way of telling these two very similar species apart. If you don’t hear them, getting a positive ID on that willow-chaff can be a tricky proposition.

Luckily there are some pointers to look out for.

I could go on to describe the various plumage and anatomical features in some detail (i.e. transcribe from my copy of the Collins Bird Guide or Advanced Bird ID Guide: The Western Palearctic – a bird book without pictures, must be for grown-ups) but I reckon the good folks at the BTO do a much better job than I could in this short YouTube video.

(Hat tip to the guys on the Birdwatch Ireland page on Facebook for pointing this video out a couple of weeks ago)
