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.
