This weekend I didn't go birding so today's individuals of Eurasian SIskin were observed one month ago. All pictures of this article was taken by digiscoping. Many birder think that digiscoping is wasteful because if we set the adapter of digiscoping, we cannot use scope as observation tools. But my tool ; TSN-DA4 from Kowa is very useful. Because we can do taking pic and observation at the same time.
マヒワ第一回冬羽♂ (Carduelis spinus) 1st-winter male Eurasian siskin 151116 Tochigi
This individual lacks the jet black and it indicates this individual is maybe young. Production of melanin takes cost so many species' young exhibit not jet black tone. Anyway, one or two years ago flock of Eurasian siskin visited my home and my mother took picture by normal digital cameras without telephoto lens.
They foraged on larch many time, but the branch of this pic is cherry tree. When one individual starts talking, other individuals also start talking. The situation is very similar to flock of Sparrow, Brambling and human!!
