There's been a Wallcreeper on coastal cliffs in SW Portugal (Cabo Sardão) found on 13th March and still present on at least 1st April. I was wondering how likely it is to stay a little longer. BWP concise states that birds occur outside breeding grounds from Oct-Apr but little else. Does anyone one know how late staying wintering birds are - or as post title, when do they arrive on their high altitude breeding grounds?
