Saker Falcon Falco cherrug
Saker Falcon is currently placed in Category D/E of the British List by the British Ornithologist's Union (BOU). Category D species are those which would otherwise appear in Category A except that there is reasonable doubt that they have ever occurred in a natural state. Those in Category E are species that have been recorded as introductions, human-assisted transportees or escapees from captivity, and whose breeding populations (if any) are thought not to be self-sustaining.
One Lincolnshire record: Kirkby-on-Bain Gravel Pits, 22nd April 1995. Accepted by BBRC in Category D (Report on Rare Birds in Great Britain in 1998).
