With 260 accepted records presented in this report, 2005 was one of the best years in the his- tory of NSKF. A total of 62 accepted records from previous years complete the status of rare birds on the Norwegian Bird list. There are 17 records presented that have been shelved. Two thirds of these concerns presumed hybrid Herring x Glaucous Gulls or first year «Eastern Yellow Wagtails». These records have been shelved due to the lack of identification knowledge in the literature for such birds. Also presented are 46 records that for some reason have not been accepted.
