Results from 2016 - recoveries and controls

Winter has made a small comeback with a cold-front over Southern Norway at the moment, the stiff NW and low temperatures means trapping is out of the question. So in stead we'll report some of the controls/recoveries we've received the past months. starting with the tits. 

Blue tits were on the move last autumn, and we ringed 1156 and controlled quite a few that were already ringed. Typically, blue tits are short-distance migrants with distances above 200 km rarely recorded. Movements typically follow the coast from the east towards the west and northwest. 

The results last autumn follow this pattern:
