Nests are no problem, for this bird prefers a graveled flat roof or some similar open space where a slight depression furnishes ample protection for the eggs. The mother shelters her eggs and young from the blistering sun which beats down.
We watch your flight on white-barred wing
And hear the notes, you try to sing,
But there’s one thing, we’d hate to try
Your way of diving from the sky.
Chimney Swift
Chaetura pelagica
Unlike swallows which bend their wings, this bird holds his wings straight, but the natural curve gives the appearance of a bow. The long wings make him appear larger than the small sparrow size which he attains. This sooty-black swift is the only member of his family which visits the eastern part of America and since he has adopted chimneys as his favorite nesting and roosting sites, he is not hard to find.
Few birds seem so perfectly fitted for living in the air and except when nesting or roosting, there is where he will be found. When flying, he looks almost like a bird without head or tail but if you will examine him closely you will find a short tail with spines which combined with his sharp claws, help anchor him to the flat inner surface of chimneys. Nests consist of small twigs which he snaps off the end of some dead limb while flying by, then glues to the chimney with saliva. This does not make an imposing structure, but is ample for safety of eggs and young.
The swift is a fast flier and combines long circular glides with quick wing beats and sharp turns, this erratic flight accompanied by a series of sharp, clicking notes which aids in identification. While drinking or bathing each bird glides down, each hitting the water in turn.
