There is a confusing array of orioles, but it is safe to say the Baltimore Oriole is the one most likely to be seen in Wisconsin. Of the eight identified US orioles only the Baltimore and occasionally the Orchard Oriole make a home here.
Orioles are noteworthy in that the males and females look somewhat similar. The female shares the same colors with the male, only slightly duller.
The male's bold orange and black colors stand out, so he is easy to identify. If you can’t find him by sight, follow his song. He has a melodic sweet sound and sings often.
Look for them in the very tops of trees where they like to hang out and build their nests.
