We seem to have a stable Red Kite population over our town these days. Generally there's one or two gliding overhead, the most I've seen is four.
I've only see one swoop down for food so far, a piece of discarded BBQ burger at a school fair on a busy playground. Stunning sight, it didn't come in smoothly (like a peregrine falcon) it almost twisted and spun as it came in to grab the food.
The local crows don't like the kites though, I've seen a few scraps with the crows trying to dive bomb them.
