Dusky Woodswallows build a frail nest of sticks in a shrub, against the trunk of a tree on a horizontal branch, behind a peeling piece of bark or even in an old fence post, etc. They breed in spring.
Dusky Woodswallows are summer migrants to Baw Baw. They prefer grassy, open woodland habitat where they soar effortlessly to catch insects on the wing. They are nearly always present in small flocks and at night, Dusky Woodswallows roost communally.
