Willow Warblers are longer winged than Chiffchaff but it isThank you Alan, this is more or less what I had gleaned from my
difficult to detect this in the field unless you can see both
species - that is my experience and is also remarked on in the
Collins guide.
The primary projection is the part of the primaries which
extend beyond the > tertials on a folded wing. Since warbler
are usually flitting around this is often hard to see.
field guides.
Personally I find the tail dipping habit of Chiffchaffs a more
reliable method of separating silent birds. There are a number
of other features that help and are listed in any decent guide
but it is never simple.
Indeed. Since it's the only time I have ever had a full view of
a Chiffchaff, and I have never had more than a fleeting glimpse
of a WW, I cheerfully admit to being a beginner when it comes to
sorting out Willowchiffs (or Willowchaffs).
The secret is to pay close attention each time you see one. Eventually you
begin to see subtle differences though it is, as Alan said, never simple.
Learn the song of WW from a recording and you'll find lots more than you
have been doing.
