Message: <blockquote data-quote="halftwo" data-source="post: 1247921" data-attributes="member: 45720">OK, so some figures worked out from this new information.This year's site is about two kilometres from where I last located the general site.It is only about five kilometres from the next nearest nest, that I know of, (if they're there this year.)I reckon the general hunting area to be in the region of 20 square kilometres - maybe quite a bit more.Obviously interpolation to a breeding density isn't possible - some studies show that loose colonies can exist - so relatively close nest sites don't go to say much.What has surprised me is that this is an area I know well & watch frequently. If that Buzzard hadn't been mobbed while I was standing there - who knows if I would have found the site.  That's what others have found - they are difficult to find.Again I can't go into details - but the site isn't one I would have anticipated as suitable, and this increases the potential number of sites vastly.</blockquote>
