A conspiracy of Ravens

Try as I might, I could not get all seven of them in shot. They cartwheeled and dove, pairing up and tumbling, cawing all the while. It is hard to believe anything except that they are enjoying the freedom of playing in the air, exercising their considerable acrobat prowess. The hills that we are on are their domain and they are not in the slightest concerned about us passing through.

A 'conspiracy' or Ravens can also be called an 'unkindness', but I could see nothing of that on a day like this.
