Immature TREE SWALLOWS can and often do show a partial brown band around
the breast and are brown in plumage, a brown much closer to Bank Swallow
color than Rough-winged. At Sturgeon Lake on Sauvie Island, a Bank
Swallow or two are often found in migration, but the Bank Swallow
look-alikes tend to predominate.
