A sky full of Buzzards! Buteos and sub-buteos!

It was a glorious afternoon here on the Heath, but I was stuck in the office putting together a large order. Nevertheless: every time I glanced from the office window there was a raptor sailing by. Most of these were Buzzards (including this well-marked displaying pair) but four Hobbies, two Sparrowhawks and at least five Kestrels came to the party as well!
