Good views and fair photos of perched bird. Appeared significantly larger and heavier than barn swallows and violet-green swallows which were also in area. Dark gray/black above, mottled white/gray/brown on throat, breast, and belly; white downy feathers visible at shoulder; white undertail coverts and notched tail. Bill relatively longer than the other swallows, with distinct down-curve. Crown dark, but back of head lighter. Bird appeared somewhat disheveled, perhaps young and/or exhausted. Moved around on its perch at top of power pole, but did not fly during 15 min. of observation. Closely resembles adult female Western illustrated in Sibley.
