Hi all you Tweeters

I have a question regarding a phrae being used lately. Whatis meant be
'atlernate plumage'?

I know what winter plumage is and eclipse, coming ot of eclipse,
immature , and breeding plumage. But what is alternate plumage?

Ananswer off line would be OK, unless there may be others out there who
also don't know what you mean by this term......

Thank you
