This Jackdaw is showing signs of being from the race `soemmerringii` which is from Finland, Russia and East Europe. You can clearly see the pale half-collar that this race of Jackdaw shows, the race that we commonly see in Britain `spermologus` does not have this collar.
Digiscoped using Lumix FS15 and Kowa TSN-883 x30
The Jackdaw looks black at a distance, but at closer range it is dark grey and not black with a blue/grey eye. They are extremely intelligent and can become quite tame where they are not persecuted. A much underated bird.
