Appearance
This woodswallow's soft-plumage is charcoal grey apart from the white underparts that give the species its English and scientific names, in contrast to the related great woodswallow whose upper side is a more glossy black. Despite its brush-tipped tongue, usually associated with nectar feeders, it catches insects on the wing.
Naming
The species was first described by Linnaeus in 1771, its specific epithet derived from the Ancient Greek words "leucos" 'white', and "rhynchos" 'bill'.
Evolution
The white-breasted woodswallow has large, pointed wings and is very agile in powered and gliding flight. This is a nomadic species, following the best conditions for flying insects, and often roosting in large flocks. The nest is a small structure built in the hollow formed by a broken branch, or in a forked branch. The normal clutch is three eggs.References:
