The Chilterns kites, contrary to what some people believe, have spread to other counties away from the core area. For obvious reasons, we don't give out the locations of nests, etc.
At this time of the year, kites will tend to congregate. They are a gregarious bird by nature, hence the annual comments by people when they visit the core area about just how many kites are around.
However, they are not territorial, except within their nesting area. They also live quite happily with the common buzzards. They will, and do, nest quite close to each other. The occasional scuffle does occur, but apart from these, they tolerate each other quite well.
A set of criteria, as set out by the IUCN must be met, prior to the reintroduction. The Chilterns met this criteria, hence the locatioin of choice for the first reintroduction in England (one also took place at the same time on the Black Isle, Scotland).
Roadkill is a common source of food for the kites. The Chilterns does provide a lot of roadkill, with the small country lanes, and large wildlife population. Roadkill of deer (particularly muntjac), rabbits, pheasants, etc are a daily occurance, and the kites (as well as the corvids and buzzards) help to keep the roads clean.
Several kites reported to me have been found on the motorway, although in general the numbers of kites killed by traffic is fortunately kept quite low. Considering the size of the kite, they are surprisingly agile, and more often than not they do manage to fly off the roadkill in time.
Winter roosts here in the Chilterns do have good numbers of 100+ birds.
If anyone does find a dead red kite (within the Chilterns area) please contact me as soon as possible. (Details on the website below). Thanks.
