"Circus aeruginosus"

Our Marsh Harrier was given to us from Green Balkans Rescue Centre in Bulgaria. He is here as an ambassador of his species. Marsh and Hen Harriers are very rare in the UK, mainly due to persecution. You can learn more about him and what you can do to support our Harriers daily in our 3.30pm conservation talk at the centre

A scarce summer visitor to Britain, marsh harriers are also found in Europe, the Middle East, Central and northern Asia, and parts of Africa. In Britain the species mainly breeds in East Anglia, but can be seen on the south and east coast as far north as Scotland whilst it is migrating. It can also occasionally be seen in Wales and Ireland. Small numbers of individuals over-winter in East Anglia, Kent and south Wales. There are records of marsh harriers in Britain that date from the Iron Age, about 3000 years ago.
