Pearl-breasted Swallow
Hirundo dimidiata
The pearl-breasted swallow is 13–14 cm long. It has glossy blue upperparts and grey-white underparts. The upper wings, underwing flight feathers and forked tail are blackish-blue. The underwing coverts are a darker shade of grey-white. The lack of white in the tail is a distinction from similar Hirundo species. The outer feathers are slightly longer in the male than the female. Juveniles are duller and browner than the adult, with shorter outer tail feathers. The northern subspecies, H. d. marwitzi is darker and smaller than nominate H. d.

White-throated Swallow
Hirundo albigularis
The white-throated swallow is 14–17 cm long. It has glossy dark blue upperparts and a bright chestnut crown. A dark blue-black breast band separates the white throat from the greyish white underparts and underwing coverts. The upper wings, underwing flight feathers and forked tail are blackish-blue, but the undertail has white patches near the feather tips. The white throat and blackish breast band are distinctions from similar Hirundo species. The outer feathers are slightly longer in the male than the female.
