While I was watching out the window, doing my bird count for the week, I saw a crow playing mid-air. He had a piece of food or maybe a twig and would fly quite high and let it drop. He would then plummet to catch it. He repeated this manouver until I lost sight of him behind the fir tree. How cool is that?
It's always the way, you think nothing is happening outside and a quick glance out of the window seems to confirm this. I find though, that after a small interval of time quietly watching, something new is always seen.
