Overall Connectivity for Blyth's Reed Warbler

There are few encounters in Europe, which are mostly concentrated in southern Finland, to a lesser extent southern Sweden, and show local movements which reflect natal or breeding dispersal or post-breeding dispersal prior to autumn migration. There is an exceptional recovery of a bird ringed in S Sweden in Sep, recaptured in S England in Nov of the same year.

Recoveries by Condition for Blyth's Reed Warbler

Over 95% of all recoveries are of recaptured birds (99% since 1991), with just 1% found dead/sick/injured

Annual Movements for Blyth's Reed Warbler

Insufficient data to properly describe annual movements. Available data show summer displacements in Europe (most encounters in Jun-Jul), due to dispersal, as shown in the ‘Overall connectivity patterns’ section.
