Revtangen BO April 15-17th

The cold weather has finally loosened it's grip, although the nights are still quite cool. Still easterlies mainly before noon, after that shifting breeze and sunny. After a quiet day on the 15th with 20 birds ringed, there was a huge influx of migrants on the 16th with 118 birds ringed. The wind was still in the E-SE but too strong for efficient trapping on the 17th, and 22 birds ringed. 118 birds in one day in mid-April is highly unusual, and the 26 Chiffchaffs and 23 Song Thrushes trapped were probably single day records for both species at Revtangen.
