The bird of prey was first seen by a couple at Victoria Tower on the east coast before being photographed by wildlife photographer Romano da Costa in St John.
It is the 13th official recording of a red kite in the Island.
Mr da Costa said: ‘They are big birds, slightly bigger than a marsh harrier. I think it was a young bird which had come over from France, probably pushed along by easterly winds.’
At one time confined to Wales as a result of persecution which continued until the 1950s, a reintroduction scheme has brought red kites back to many parts of England and Scotland.
There are now believed to be more than 2,000 breeding pairs across the British Isles.
