Museum Yearbook


	Annually, around 250,000 wild birds are ringed (or banded as they say in the US) in Norway. The results of the birdringing tells us where our breeding birds have their migration routes, and important resting- and wintering areas. By trapping and ringing bird we also acquire important data about the proportion of juveniles and adults in the population on a year-to-year basis, data which is of critical importance to explain any population decrease or increase. When ringed birds are recovered, we can calculate the life expectancy and acquire knowledge of important causes of death. All this information is essential for managing bird populations in a good way. All scientific birdringing in Norway is organized by the Ringing Centre at Museum Stavanger. Since its beginning in 1914, more than 7 million birds have been ringed. The museum also has its own field station, Revtangen ornithological station. This was the first bird observatory to be established in the Nordic countries when it was opened in 1937. At Revtangen we capture and ring 6-12000 wading- and passerine birds each year. Read more about the work at Revtangen at http://revtangen.blogspot.com If you find a ringed bird we would like you to report this to the Ringing Centre.

Always state the nearest location which can be found on a map, together with the name of the county and municipality. If you found it in your garden, please state your street address. • Information concerning the find. How was the bird found? If it was found dead, it would be of interest to know something about how long the bird had been dead (recently, rotting, skeleton, etc). If only the ring was found without a trace of the bird, please pass on this information. • If possible, send us the ring. Most rings can be flattened and secured with tape. We would also appreciate that the ring number be written in the letter as the ring can fall out of the envelope. • Your name and address. Everyone who sends information about a ring marked bird will receive a reply as to where and when the bird was ringed, etc. If you have an e-mail address, please include this and you will receive the recovery letter by e-mail.
