Red Kites

According to the RSPB, this magnificently graceful bird of prey is unmistakable with its reddish-brown body, angled wings and deeply forked tail. It was saved from national extinction by one of the world's longest running protection programmes, and has now been successfully re-introduced to England and Scotland.

In the UK, the population that survived the persecution in the old oakwoods of mid-Wales has spread, and continues to go from strength to strength. In England the reintroduced birds can be found in the Buckinghamshire/Oxfordshire area, Hertfordshire, Northamptonshire, Yorkshire, Gateshead, Northumberland and the Newcastle area and Grizedale Forest in Cumbria. The Scottish population is centred around the release sites in Dumfries and Galloway, Stirling-shire and west Perthshire, around Black Isle in Ross-shire, and on the outskirts of Aberdeen City. Kites have also now been returned to Northern Ireland.
