As part of a PhD study based at Anglia Polytechnic University in Cambridge, long-life radio transmitters were fitted to 8 young kites while they were still in the nest. Two of the birds unfortunately died before fledging, and another two were subsequently killed by an illegal poison bait. Another dispersed away from the Midlands leaving only three in the breeding area at the time of writing. The radios will allow the movements of these birds to be monitored for about the next three years before the batteries begin to run down.
Radio-tracking of birds tagged in previous years has already shown that some young kites disperse away from the Midlands, either in their first autumn or during the following spring. Some join kites in other areas, particularly the populations in mid-Wales and the Chilterns although many subsequently return to the Midlands when ready to breed for the first time.
As usual young kites reared this year were fitted with coloured plastic wing-tags while still in the nest. Birds were given a white tag on the left wing and a bright pink tag on the right wing.
The biggest threat to reintroduced kites comes from illegal persecution, particularly the indiscriminate use of poison baits in the open countryside. A recent incident in this area, the worst since the start of the re-introduction programme in England, resulted in the deaths of at least three of this year's young. Poison baits of this kind are not only a threat to kites but to many other species of wildlife and also to domestic animals such as cats and dogs. A local businessman was so incensed that he has offered a £2,000 reward for information leading to a conviction. The Police are continuing with their investigations and so we are unable to give any further details at this stage.
