According to the USGS site: http://www.pwrc.usgs.gov/bbl/homepage/swan.cfm
this is why the collar is U856 and not 958n: *Tundra Swan* - gray, black or blue collars - gray collars used on wintering birds in the Atlantic Flyway - black collars used on migration routes - blue collars used in the arctic on or near the breeding grounds - 4 character combinations with the letter first (LNNN) - or - - 3 character combinations with two letters (LLN, LNL, NLL) So if there are 4 digits on the collar, it's letter-first followed by 3 numbers. Hope that helps!
