The white-breasted woodswallow (Artamus leucoryn) is a medium-sized passerine bird which breeds from the Andaman Islands east through Indonesia and northern Australia.

[2][3] His account was based on "la pie-griesche de Manille" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson.

[5] The white-breasted woodswallow is now one of 11 species placed in the genus Artamus that was introduced in 1816 by Louis Pierre Vieillot.

[6] Nine subspecies are recognised:[6] The white-breasted woodswallow's plumage is dark grey on the head and neck, with white underparts, giving the species its common and scientific names, in contrast to the related great woodswallow whose upper side is a more glossy black.

They are partially migratory, with southern flocks moving north during Autumn and returning south in the spring.

The white-breasted woodswallow has large, pointed wings and is very agile in powered and gliding flight.

Out of breeding season, woodswallows are quite nomadic, chasing flying insects and roosting in large flocks.

The female sexual display to invite copulation includes extending the wings over the back in a V, whilst trembling toward a male/s, then waggling the tail and quietly making an 'eep' call.

[12] Although they mostly feed on insects caught in flight, woodswallows also forage on the ground or in the tree canopy.
