A few more birds to report from the Metrocenter area: After a few frustrating hours at Comcast I walked over to the canal near the intersection of Mainstream Drive and Freeland Station Road. In the canal between the Comcast building and the athletic fields on the east side of Mainstream I had good looks at a Black-crowned Night-Heron and at least four Hooded Mergansers. The mergansers were swimming away from me along the bank in and out of vegetation so I had a hard time getting an exact count. I also spooked a Great Blue Heron and heard a Belted Kingfisher along the canal that parallels Freeland Station Road. Apologies if I'm reporting unremarkable birds, it was a nice way to break up boring Monday errands. Neil Kelley Nashville, Davidson County
