What's flying near you?

The crows are back in their nest in the top at the oak tree and the squirrels are trying to pinch their eggs.
Its great fun watching them as the crow tries to attack the squirrel as its runs up the tree - but the squirrel knows that it only has to swing around to the other side of the trunk and the crow can't change direction fast enough to get him. I've watched the squirrel spreadeagled, motionless on the trunk and the crow flying away from the tree to another one to make the squirrel think its safe. Suddenly, in comes the crow like a black rocket, the squirrel twists around the trunk and the crow misses yet again. Squirrel runs along a branch and leaps off into another tree, hotly pursued by the crow and off they go, chasing through the trees until the crow decides he'd better go back to his partner in the nest.
