Ringing activity in Merkeskogen and Herberg resulted in a few good records such as Arctic Warbler on the 10th plus Yellow-browed Warblers, Olive-backed Pipit and Little Bunting.
Ringing:
There were 14 days of ringing in September in Merkeskogen. A total of 439 individuals of 36 species were ringed. The best day was the 27th when 56 individuals were ringed of which Robin (17), Goldcrest (20) and Blackcap (7) were the most prominent species. Notable species ringed during the month were Arctic Warbler, Blyth’s Reed Warbler, Olive-backed Pipit (2), Little Bunting (2), Red-breasted Flycatcher and 26 Yellow-browed Warbler.
