Revtangen BO November 9th-24th

Most migrants have left and most bird observatories have closed, but Revtangen BO never close! Ringing was carried out on 8 days between November 9th and 24th. After a cold start to the month we've had a quite long and stable period dominated by mild E-SE. Visible migration is limited to a continued northbound movement of Eurasian Siskins, still sizeable flocks moving this weekend on the 23rd-24th. We have taken down some of the nets, and most trapping now occurs around the feeder. In addition, playback on Twite have been quite successfull in the southern end of the trapping area, and we've now ringed 60 in total, most in November.


60 Twite is the hightest number at the BO since 1971. This is a result of a higher effort on playback than before, rather than a huge population increase, but there also seems to be more Twites around than usual.
