One male and one female
Were feeding on a old Picea abies. Heard that these trees have a massive seed production the last season before they die. This tree was the only common spruce in that area offering seeds. The crossbills really enjoyed it;)
This was the first time I saw this species. For me and two friends it was one of the highlights of that area.
The Saxonian Suisse is one of the most interesting natural reserves in Germany.
