Hi, I did a survey at the Patuxent Research Refuge North Tract last evening, and came up with 13 warbler species, including a Nashville right along Wildlife Loop. The bird was incessantly singing its two-parted song in a small island of trees on the left side of the loop just past the Upland Dog Training Area, and just prior to Duvall Bridge Rd. The clump of trees and underbrush sits in front of the Duvall Cemetery. You don't even need to get out of your car for this one. This bird was sitting less than 200 yards from where I found my only 1998 Nashville Warbler, last April. Also picked up was my first ACADIAN FLYCATCHER of the season, singing along the river trail by the Visitor Contact Station. At the Wildlife viewing area ten PURPLE MARTINS were counted, now established in the martin house there. First Canada Goose goslings were seen last Wednesday, 28 April. Stan Arnold Glen Burnie, MD
