Revtangen BO August 1st-16th

August has been very variable so far regarding the weather. A couple of periods of warm and nice, but also periods with northerlies and westerlies. There has been quite strong invasive movements of Common Crossbill, with around 1000 birds moving north at Revtangen BO on a single day early in the month. Wader ringing has been very poor with regards to Tringa-waders by the observatory pools. Mist-nets were used in the trapping area on 9 days during 1st-16th, but only on day with all nets operational.

Reed Warbler is a target species in August. 1 cy. Rørsanger 1K.
