The Barn Swallows wereeasily told by the bluish back andforked tail. I believe these are verylate records, especially for the BarnSwallow as the last fall record of BarnSwallow for Washington, D. C. (about1;0 miles south of York) is September17th and October 14th for the TreeSwallow. A week later on October 20th, wevisited the same place and saw asingle Barn Swallow, but no TreeSwallows.
