Striated Swallow

he striated swallow (Cecropis striolata) is a species of swallow found in open, often hilly, areas with clearings and cultivation across Southeast Asia to northeastern India and Taiwan. The striated swallow was formerly sometimes considered a subspecies of the red-rumped swallow. The striated swallow is 19 cm long with a deeply forked tail. It has blue upperparts other than a reddish collar (sometimes absent) and streaked chestnut rump. The face and underparts are white with heavy dark streaking. The wings are brown. The sexes are alike but juveniles are duller and browner, with a paler rump and shorter outer tail feathers. The contact call is pin, the alarm is chi-chi-chi, and the song is a soft twittering.
