Birds of Kentucky: Cliff Swallow Colony, Bliss Road

No evidence of the beautiful insect-consuming birds who live here, but during an earlier visit the adult cliff swallows put on quite an aerial show. The entire tunnel under the LBN Parkway is lined with dozens of clusters like the one above. Didn't get a chance to count the individual nests, but would estimate at least 200. - EW Comments | Permalink
