As a bit of a novice, can I ask.... How do you know?
I had my first chiffchaff of the year in Northumberland a whole week earlier than I've seen/heard one before (on 13th March) and was told on this forum (and other places) it would have been a resident. I guess the timing was important for my sighting - being too early to be a spring arrival - but how do you know the flocks you are seeing are over-wintering birds?
