No, this is Certhia brachydactyla, Short-toed Treecreeper.

Thank you very much, dear Frank. I keep wondering how long the toe and nail of the macrodactyla might be!

Thank you very much, dear Frank. I keep wondering how long the toe and nail of the macrodactyla might be!

The differences between length of hind toe and hind nail of the two species are slight and hardly ever that much that this represents a helpfull field character. Only the extreme cases are usefull in the field without real measuring. You should compare the length of the hind toe A with that of the hind nail B. When A is (very) obviously > B it should be C. brachydactyla and when A is (very) clearly < B it should be familiaris/macrodactyla. Look at the picture: in most cases it is like this, in fact too close to tell (for sure) and I should always try to see the other characters in the wings.
