1 Ringstørrelser Dette er en oversikt over ringstørrelsene fra Stavanger Museum. Det er gjort noen endringer siden forrige liste, de viktigste er markert i rødt. Når det gjelder Oslo-ringer så henvises det til egen liste. Artene er oppført systematisk med tilhørende ringstørrelse. I denne listen er artsnummer (EURING) sløyfet da arts- og underartskodene ligger i RingAccess. For lommer, dykkere, gjess, ender, svaner, rikser, hønsefugler, tyrkerdue og trane utvikles tarsen sent på pullus. Merking må derfor ikke finne sted før tarsen er fullt utviklet. «=» mellom to ringstørrelser betyr at begge kan brukes, men førstnevnte er å foretrekke. «*» bak ringstørrelsen betyr at det bør benyttes stålring, kun angitt der ringstørrelsen produseres i begge typer metall. «@» = spesialtilpasning av JD-ring Det finnes en del spesialringer til enkelte arter: BA aluminiumsring med lukkeklaff for hubro og snøugle 2 - aluminiumsring med lukkeklaff for lappugle og slagugle HA spesialring for smålom og storlom. Den har en spiss trekantet form tilpasset fuglens tars. N spesialring for alke. Den har en trekantet form tilpasset fuglens tars. J spesialring for lomvi og polarlomvi. Den har en trekantet form tilpasset fuglens tars. FA ring utviklet spesielt for gråmåke og alkefugl. Størrelse mellom 3 og 4. JD spesialring for perleugle. Den har samme diameter som 5, men er lavere. Brukes også på tyrkerdue, men da bør man ta en avbiter og klippe av ca. 2 mm på den ene siden. MD spesialring for spurveugle. Den har samme diameter som 6, men er lavere. K ring med størrelse mellom 6 og DA. T spesialring for tårnseiler. Den har samme diameter som 8+, men er lavere. For havørn og kongeørn finnes det egne prosjektringer. Helt bakerst i listen finner dere oversikt over alle ringtyper med innvendig diameter.

2 Ring sizes This is a list ring sizes of rings issued by Stavanger Museum. For Oslo-rings there is a separate list. The species are listed systematically with associate ring size. The species EURING-code are left out of this list as these are coded in the RingAccess-software. For pulli of loons, divers, geese, ducks, swans, rails, Galliformes, Collared Dove and Crane, the tarsus develops quite late. Marking should not take place until the tarsus is fully developed. «=» Between two ring sizes means that both can be used, but the former is preferable. «*» Behind the ring size indicate that steel rings must be used, only indicated for ring sizes that are produced in both aluminium and steel. «@» Adjustment of JD-ring There is a number of customized rings for certain species: BA - aluminum ring with a closing mechanism for Eagle Owl and Snowy Owl 2 - aluminum ring with a closing mechanism for Great Grey Owl and Ural Owl HA - special ring for Red- and Black Throated Loon. It has a triangular shape. N - special ring for Razorbill. It has a triangular shape adapted to the bird s tarsus. J - special ring for Common- and Brünnich's Guillemot. It has a triangular shape. FA - ring designed specifically for Herring Gull and auks. Size of between 3 and 4. JD - special ring for Tengmalm s Owl. It has the same diameter as 5 but is lower. Also used on Collared Dove, but then the ring should be cut by approximately 2 mm. MD - Special ring for Eurasian Pygmy Owl. It has the same diameter as 6 but is lower. K - ring with size between 6 and DA. T - Special ring for Common Swifts. It has the same diameter as 8+, but is lower. For White-Tailed- and Golden Eagle there are separate project rings. In the final section of this document there is a list with the inner diameter of the different types of rings.
