Revtangen BO April 23

Today there was finally a significant change in the weather, with the wind picking up and increasing to 10-12 m/s from ESE, and the night temperature increasing with about 5 degrees to around 10, and 19-20 degrees and sunny during the day. A real summers day, and it triggered a massive arrival of migrants. Nets open 06-14.30, and again 17-20.30. Netmeter hours approx. 3500. The wind was much too strong for efficient trapping and some nets were not in use, but the high number of birds produced a good catch in those nets that were not too affected by the wind.



Both Ring Ouzel (top) and Lesser Whitethroat were new in today. Ring Ouzels are svarce at Revtangen BO and 1-2 are ringed most years.

Ringing total April 23rd: European Robin 54, Common Redstart 5 (first this season), Common Blackbird 1, Ring Ouzel 1 (first this season), Song Thrush 12, Blackcap 13, Lesser Whitethroat 1 (first this season), Willow Warbler 22, Chiffchaff 12, Goldcrest 5, House Sparrow 3, Brambling 1, Lesser Redpoll 2, Mealy Redpoll 3, Common Linnet 1. Total = 136.
