Fran, Places to see Baltimore Orioles around Baltimore. At Cromwell Valley Park on Cromwell Bridge Rd. south of Loch Raven Dam is one of great place to see Baltimore Orioles at nest, we have over 20 pairs of Baltimore Orioles nest there along with dozens of Orchard Orioles. Also at Baltimore Zoo in Druid Hill Park has a first record of Baltimore Orioles' nest along Waterfowl Lake. Both of these places have a good migration of Baltimore Orioles during first week of May.
