Résumé :	As a consequence of a recent review by BOURC, there are now just four accepted British records of the Hawk Owl Surnia ulula. A bird of the North American race S. u. caparoch, found in an exhausted state on board a ship off the coast of Cornwall in March 1830, remains the first acceptable British record. The other three records, two of which date from the late nineteenth century, involve the nominate race, which breeds in Scandinavia. The only recent record refers to a bird in Shetland in September 1983, and this Hawk Owl remains on Category A of the British List. A summary of racial identification and ageing is presented, and taxonomy, distribution and irruptions are discussed briefly.
