Thanks for that oriole article. I live in Maryland, where the Baltimore Oriole is our state bird, and in the past three decades I've only ever seen one oriole in my yard—or anywhere! The tips on using the color orange and to feed orange halves and dark organic grape jelly is something I can try.
I know that crows and ravens like the color blue, so I have a large blue plastic tray that I put bird seed out on, and they can see it from the air.
Found this, for anyone interested in what plants attract various species:

A. W. Thanks! Forwarded to my family! Wikipedia has more on Orioles. I think that I am just out of their range.
