The humblest bird there is, such a sweet thing.
* The House Sparrow was introduced into Brooklyn, New York, in 1851. By 1900 it had spread to the Rocky Mountains. Its spread throughout the West was aided by additional introductions in San Francisco, California, and Salt Lake City, Utah.
* The House Sparrow has been present in North America long enough for evolution to have influenced their morphology. Populations in the north are larger than those in the south, as is generally true for native species (a relationship known as Bergman's Rule).
* Although not a water bird, the House Sparrow can swim if it needs to, such as to escape a predator. Sparrows caught in a trap over a water dish tried to escape by diving into the water and swimming underwater from one part of the trap to another.
* The House Sparrow is a frequent dust bather. It throws soil and dust over its body feathers, just as if it were bathing with water.
