Look at the picture I have attached (the skull should be the skull of a Nuthatch, although the bill looks a bit strange probably due to the angle).The bill is 17 mm to the tip of the feathering, not to the skull. I would guess that the bill extends a bit further behind the feathering (like it always does on birds), in any case I can't see the skull in the picture. The wing length can be only grossly estimated based on the picture, you don't even see the entire primaries. The length of the visible part of the primaries is about 70 mm, the rest is just speculation. A wing length of say 85 mm seems completely plausible to me.Some measurements for ssp caesia: wing 81-91 mm, bill to skull 18.0-22.2 mm. Ssp hispaniensis occurs in Portugal, don't have any measurements for that. To me these measures fit extremely well the subject bird. I can only conclude that it is a Nuthatch, a species that frequently visits gardens.</blockquote>
