Parts that have fallen off...
You don't get to see a Turdus merula or a blackbird often. They don't usually visit Vilnius center or suburbs. You have to get out of the city or visit one of the larger parks, surrounding Vilnius down town like a wall.
The bird was moving like a panther of the bird world. But not much catlike as one would think. I would say it moved in a less jerky manner, compared to other small birds. And it was really hunting-a short run-stop, look look, jump-attack, kill.
My society finches move in a similar way-fluently somehow. But they only hunt for seeds and cucumbers.
Poor things look rather stupid compared to the wild bird.
