Media notes
I believe Tree Swallow (male) on the left, Purple Martin on the right. Purple Martin has a gray collar, significantly longer wings (18") than the Tree Swallow (14.5") and very slender rump and tail area compared to Northern Rough-winged Swallow. The wingspan of Northern Rough-Winged is slightly less (14") than that of the Tree Swallow.
