Trumplings actually have a bit of history in MD. I quickly pulled these 3 Baltimore Sun articles from Google by searching "Trumpling Sladen":

I didn't think there were any more around, but we did have a suspected one show up at Black Hills in January 2005. You can read about that in the MDOsprey archives:

Birding is always interesting!
