Summary of the 2017 season

The 2017 season was a wet and windy one, and this had a negative impact on the season total on the Bird Observatory. The spring total was decent and there were 3 days with more than 100 birds in the catch, unusual in spring. Autumn came, as many times before, with wind and rain and there was not a single period with stable nice weather for more than a few days. In particular, the latter half of October and all of November was dominated by wet and windy weather. This was unfortunate, since there were some interesting irruptions of woodpeckers and redpolls that went under-recorded. A big thanks to everyone who participated and all our visitors!
