Hello all, Went to Conowingo at 1:30pm before return to work at 3pm. First I stopped by at Harve De Grace to see the possible Slaty-backed Gull, after arrive there at 1:00pm, found the bird at 1:10pm going upriver on Cecil side, seen from the boardwalk. The reason I know this bird was at Harve De Grace, because I check the other e-mail from someone who saw the bird and it is only seen in early morning and in the evening at the dam, and between 10am-3pm somewhere upriver or downriver. I couldn't count the Ring-billed Gulls, because I was still sick (headache & sore throat) from a rough trip to Bridge-Tunnel on Sat. I left at 2:30pm today to go to work at Fallston Veterinary Clinic, Inc. (3pm-7pm), a hospital for dogs, cats, and birds. Rick Blom and his gang was at the dam today before I came at 1:30pm. Other birds seen: Common Loon - 1 upriver Great Blue Heron - 95 prs. at nests on Cecil side, counted 113 nests, but few are empty. Black-crowned Night Heron - a pr. at nest at rookery, & a imm. at island Tundra Swan - 2 seen in flight toward north Canada Geese - 2 at south end of island Common Merganser - 53 above dam Bufflehead - 5 LESSER BLACK-BACKED GULL - 4 (1 ad., 1 1st winter, & 2 3rd winter) ICELAND GULL - 2 (1 ad. & 1 3rd winter at the wall and behind) THAYER'S GULL - 1 (1st winter) flying around behind wall CALIFORNIA GULL - 1 (2nd winter - swimming behind the wall) GLAUCOUS GULL - none today Ring-billed Gull - hard to count with a headache, estimate. at 19,000-20,000 Herring Gull - 1,006 Great Black-backed Gull - 384 Bald Eagle - 5 (2 ad., 1 1st winter & 2 2nd winter) Turkey Vulture - 13 Black Vulture - 58 all perched on several trees above the Visitor Center Rock Dove - 143 Red-bellied Woodpecker - 1 N.
