Swale Wader Group

 

The wader ringing session at Harty over the night of the 17th/18th September was very successful with 87 birds caught. Seven ringers made the team and the weather conditions were good with almost no wind and no moon.

The catch included 82 new birds plus 4 retraps (2 of which were re-ringed given the age of the existing rings - see details of retraps below) and 1 control of a UK ringed Bar-tailed Godwit.

The 82 new birds included:

  • Black-tailed Godwit - 22 (all adults)
  • Redshank - 22

  • Bar-tailed Godwit - 12
  • Curlew - 7 (all adults)
