Barn Swallows nest just as well with or without substructure and they will hang a nest in the same manner as a Cliff Swallow. A prime example is under the Obion River Bridge on the Great River Road where they are lined up and sometime alternate as to species. Another location where there are thousands of Cliff Swallow nests is under the I-40 bridge over the TN River where both species again nest side by side but there are only a hand full of Barn Swallows at this location. Barn are in the extreme minority in any of these locations. I think it might be the case where the Barn Swallows are opportunistic because I've seen them finish a partial Cliff Swallow's nest and raise young. Good Birding!!! Jeff R.
