The tree mountain swallow is a small bird from the swallow family. It lives in Australia, flies quickly, and catches insects in the air.
The tree mountain swallow differs from related swallows by nesting in tree hollows rather than building mud nests on walls. It is important for nature because it destroys a large number of harmful insects.
