Short-toed Treecreeper - Similar to the treecreepers we have in Britain and Ireland but for the plumage being of a more brownish flanks and the bill being very slightly longer. The shorter toes are the hind toes. Not visible in this image. Bill and feather pattern and habitat identified this bird. Photographed in Vilamoura Portugal from the hotel balcony!. Not the best of images I know but all I could master in the time I had! Better luck next time!
