Any sightings of kites outside the core areas of Buckinghamshire/Oxfordshire and central Wales need to be reported to the RSPB. All the birds released as a part of the re-introduction programme were fitted with coloured wing tags, each with a number/letter combination that allows for individual recognition. Details of wing tags will particularly helpful. This will help with monitoring the whereabouts and movements of the tagged individuals and the spread of the kite population as a whole.
