The reason for this is to try and discover if there are any seasonal differences in the island's population and mainly in an attempt to find if that any of our wintering birds are of the Scandinavian race A.p.littoralis. In a few weeks more Rock Pipits will arrive on the island and we hope that some will show characters of the Scandinavian race.

A fine selection of colours are added to the legs. - To report sightings the colour and positions of each ring needs to be noted and on which leg the metal ring is on.

Below are some images taken a few years ago of two completely different looking Rock Pipits. The bird on the left was considered to be a Littoralis Pipi. Note the much whiter outer tail feathers (similar to Water Pipit), The bird is larger, paler and greyer, with slightly browner legs, more diffuse streaking.
We are hoping to catch more and add colour rings, but since we began the colour ringing four years ago, we have trapped 350 nominate Rock Pipits, but NO Littloralis!
