[mou] Swan ID

[patrick.beauzay@ndsu.edu]

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!

Pat
