Hello all, A fellow ND birder asked me about the trumpeter swans I saw in Wadena County over the weekend and how to differentiate between trumpeter and tundra swans. As I was reading the snowy owl ID link sent by Mark Alt this morning, I came across this very good swan ID page at the Cornell U bird website:
http://www.birds.cornell.edu/crows/SwanID.htm It has good photographic comparisons of the two species, and covers the best ID characters for both species. Good birding!
