Ernest Seton - Bird Portraits

The Swift builds, as is well known, in the flues of chimneys. It is often seen in May, dashing past the dead twigs of some tree, and then off to the chimney, where the twigs are glued together and to the bricks by the help of saliva secreted by the bird. A common and distressing experience after a storm in summer is the discovery of the young Chimney Swifts at the wrong end of the chimney, – on the hearth, in other words. Even in their proper place in the chimney, the young birds can make their presence very well known by beginning, as soon as it is light, an incessant clamor for food.

The long narrow wings, the powerful chest muscles, the cut of the bird's body, and the way the keel is ballasted, so to speak, enable the bird to remain for hours in constant flight without apparently experiencing the least fatigue. Swallows are often seen resting on telegraph wires, but I have never seen a Swift perch on any support outside a chimney. At night and during such part of the day as is given up to rest, the bird supports itself in chimneys by clinging to projections or crevices. The stiff, sharp-pointed tail feathers aid greatly in supporting it. Before the coming of the white man, hollow trees served as the roosting and nesting places of the Swifts.
