Hello!

Another useful mark for distinguishing perched common and lesser nighthawk:
the light primary bar on the lesser nighthawk is located beyond the tips of
the tertials on the bird's folded wing. On a common nighthawk the tertials
extend relatively far past the primary bar.

Good birding,
Tessa Rhinehart (Isla Vista)
