This is the only British species of its genus, and is with Periodical 
us a summer periodical visitant. Vane 
The Swift is seldom seen in the northern parts of England 
_ before the end of May, or the begining of June; in the 
south it arrives a week or two earlier. It leaves us again for 
warmer climates in August, a month or six weeks previous to 
the departure of the Swallows. In this country it haunts 
cathedrals, towers, churches, and other buildings not con- 
stantly inhabited, in the holes, and under the eaves of which 
it finds a safe retreat, and proper situation to build in.—The Nest, &c. 
nest is formed of straw and other suitable materials, which 
it collects with great dexterity in its flight. 
These are cemented together, and the inside of the nest is 
plastered with a viscid substance, furnished by glands pecu- 
liar to certain birds of this genus. The eggs are usually 
two, but Temmincx says three or four, of a transparent 
pinkish-white. The form of the Swift is admirably adapted 
to its mode of life, the greater part of which is passed in 
floating through the air. Its head is broad and flat, the neck 
very short, and the wings longer in proportion to its size and 
weight, than those of any other bird. Except during the 
short periods of nightly repose, the Swift is constantly upon
