For my posting of this Swallow yesterday, Tom Murray suggested that it might be a Northern Rough-winged Swallow, rather than a Bank Swallow as I had named it. The top image here is a back/top view of the same Swallow. For comparison of the two, I've placed yesterday's posting below. On closer checking, I tend to agree with Tom but would appreciate input from others w.r.t. the I.D. before I rename it. I've now renamed it as a Northern Rough-winged Swallow. Thanks to Tom and Christine for their help.
