| | Common Swift - Wikipedia, the free encyclopedia |
 | | Swifts will occasionally live in forests, but they have adapted more commonly to human sites and will build their nests in all suitable hollows in buildings, under window sills, in the corner rafters of wooden buildings, in chimneys, and in smokestacks. |
 | | Common Swifts are 16-17 cm long and entirely flish-brown except for a small white or pale grey patch on their chins which is not visible from a distance. |
 | | The heraldic bird known as the "martlet", which is represented without feet, may have been based on the swift, but is generally assumed to refer to the House Martin; it was used for the arms of younger sons, perhaps because it symbolized their landless wandering. |
