Went last night to try to relocate the little blue found on the may count saturday. No luck with him but did find YELLOW CROWNED NIGHT HERON, an adult in beautiful plumage. A treat for me since they are rarely seen here in Ho Co (most are juvs. which I always appreciate but WOW the adults are spectacular!) On the return down the lake the YC had left and there was an adult BLACK CROWNED! The YC might have still been around somewhere but we didn't see him along the main lake edge. Other goodies were BANK SWALLOW, only one bird that briefly swept through. Two COMMON NIGHTHAWKS made an appearance also. Bonnie Ott (ellicott city)
