How far does a kite range?

Hi all,

In the Identify This! thread, I put up a photo of a fuzzy blob that had characteristics of a red kite. Now, the day before yesterday, I did get a picture of a red kite. It was some way a way by the time we had both found a gap in the trees through which it could be photographed.

 

Now, this one was spotted in my brother's field, which is about 2 miles, as the kite flies, from where I photographed the fuzzy one. So, the question is - am I seeing two kites or one? Are they territorial? Do they range each other's terrritories?

Cheers
Steve

PS - the nice thing about the kite is that, although I've never seen one before except on TV programmes ages ago, and in photos, the minute I saw it, it couldn't be anything else, even before it tilted enough to show me the forked tail.
