Eggs (Guide)
Usually 2; white. Incubation: by both sexes.
Subspecies
No subspecies.
Red-rumped Swallow (Cecropis daurica) (Dowsett and Forbes-Watson 1993), Striated Swallow (Hirundo striolata) (Sibley and Monroe 1990, 1993) and Rufous-bellied Swallow (Hirundo badia) (given specific status by Turner 2004) have been lumped into Hirundo daurica because examination of morphological differences suggests size and boldness of streaking are clinal characters and evidence for sympatric breeding and reported vocal differences is inadequate.
Forms a superspecies with Red-rumped Swallow (Cecropis daurica) and Striated Swallow (Hirundo striolata), the three replacing each other geographically, and often treated as conspecific, especially with Striated Swallow (Hirundo striolata), but recent review suggests that they are separate species.
