Masked Woodswallow
Artamus personatus

The Masked Woodswallow is a small bird (18-20 cm), which is found across much of Australia and is very similar to the closely-related Black-faced Woodswallow, which has only a small black patch on the face. As with other woodswallows, they are quite aerobatic and can soar and hawk for insects easily.
