okay, just my thought on it. didn't know they interbreeded.
How are you able to differentiate them from a photograph when the only reliable method is by DNA analysis and using biometrics. The two species are known to freely interbreed where the range overlaps. All first winter birds are very colourful while old adults have virtually no colour at all. Since these birds are migratory and they are only seen here in winter it is very likely that they are all collybita.
could possibly be a common chiffchaff, http://en.wikipedia.org/wiki/Common_Chif... but i lean towards iberian. take your pick, common look a bit bigger
