Ashy woodswallow
The ashy woodswallow (''Artamus fuscus'') sometimes also called the ashy swallow-shrike is a woodswallow which is found in south Asia. Like other woodswallows, it has a short curve bill and a short square tail and long wings. It is usually seen perched in groups, high on powerlines, tall bare trees and most often in areas with a predominance of tall palm trees.
==Description==
This stocky woodswallow has an ashy grey upperparts with a darker head and a narrow pale band on the rump. The underside is pinkish grey and the short slaty black tail is tipped in white. The finch-like bill is silvery. In flight the long wing looks very broad at the base giving it a very triangular outline. The first primary is very short. The legs are short and the birds usually perch on high vantage points from which they make aerial sallies. There are no geographic variations in plumage and no subspecies have been designated.
Males and females are indistinguishable in the field, however an old report suggests that the sexes differ in the colour of the inside of the mouth. Young birds appear barred on the underside.〔
