This is the 30th annual report and the 31st announcement from the Norwegian Rarities Committee (NSKF). The majority of records treated here are from 2005, but some older records are also included. Norway follows taxonomic advises given by the Taxonomic Advisory Committee (TAC) in the Association of European Record and Rarities Committees (AERC). The systematic list of accepted records is set out in the following system: (1) The bird's Norwegian name, (2) scientific name, (3) the numbers in brackets, e.g. (2, 30/32, 1), refers respectively to the (i) total number of records/total number of individuals up to and including 1974, (ii) total number of records/total number of individuals from 1975 (the foundation year of NSKF), except (iii) records/individuals in 2005, (4) any breeding, (5) year, (6) county, (7) number of individuals, age (1K = first calendar year etc.), sex (if known) and sometimes circumstances («rm» means that the bird was ringed), (8) site and municipality, (9) date, (10) * indicates if the record was complemented by positive evidence, and type of the evidence (F = photo, V = video-recorded, L = tape-recorded, D = found dead), (11) observers' names in brackets, main observer(s) is specified first and emphasized with *, (12) roughly gives the species' distribution and (13) comments concerning the records.
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. Record numbers for Norway was recorded for the following species during 2005: White-rumped Sandpiper Calidris fuscicollis (four records involving five birds), Barn Owl Tyto alba (three records), Desert Wheatear Oenanthe deserti (five records), Black-throated Thrush Turdus ruficollis atrogularis (four records) and Arctic Warbler Phylloscopus borealis (11 records involving 15 birds). Also, 2005 was the first year ever with multiple records of Ross's Gull Rhodostethia rosea (two records), Pallid Swift Apus pallidus (two records involving three birds) and Steppe Grey Shrike Lanius meridionalis pallidirostris (two records). Four records of «Eastern» Stonechat Saxicola torquatus maurus/stejnegeri were also an all time high.
