Cromwell Valley Park has a good breeding of Baltimore Orioles in the past few years. Last summer about 20 or so breeding pairs nesting there along with Orchard Orioles. Last summer The Baltimore Zoo has a first oriole's nest near the Waterfowl Lake. If you have questions about the orioles you can sent email to me at ggraff@erols.com or call my friend Jim at 410-435-2008. Cheers Kevin Graff
