The black swifts wheel overhead, and the white-breasted swallows float in the azure.
"Hodge and His Masters"
Richard Jefferies
Swallows, martins, and swifts were numerous, the martins especially, and it was beautiful to see them for ever wheeling about in a loose swarm about the building.

Nothing in fact was the same, for when I looked for the swifts there were no more than about twenty birds instead of over a hundred, and although just on the eve of departure they were not behaving in the same excited manner.
