2 Long-eared Owls (Asio otus) ringed in April |
As we started in the middle of April not many birds were caught. It was two not bad days with few tens of birds in the nets. In the other days they were very quiet or migrating too high. 86 individuals of 19 species were ringed. Most numerous in the nets were Red-flanked Bluetails (Tarsiger cyanurus) - 40 birds ringed.
