I wanted to post this for anyone birding along the south coast today. I probably had a Cave Swallow yesterday, but due to poor lighting and limited views, as well as rain, I couldn't rule out a Rough-winged or Cliff Swallow. I viewed the bird three or four times just as the rain started. The one good ventral view as it flew overhead indicated that it was definitely not a TRES. The area under the throat looked a bit dusky like a NRWS, but did not seem as dark as a CLSW. Unfortunately I never got a dorsal view before the bird disappeared.
Look closely at the swallows that are floating around York county....
Good birding,
tom
