Long-tailed tits are easier to spot now that the leaves are coming off. They like to flit through the world in little groups titting away to each other. You hear them arrive and by the time you have spotted them they are off to the next bush or tree in their quest for hibernating insects.
If you get a close up view you can see their detailed black and white colouring with pinkish shoulders, and of course their long, black and white tails.
But they are constantly on the move, acrobatically searching the trees for food.
