The house or English sparrow is perhaps the best known species. It inhabits the British islands and other parts of Europe, from which it has been introduced into America, where it is now regarded as a pest. Their amazing fecundity, their strong attachment to their young, their familiarity, not to say impudence, and their voracity are familiar to all. They often do great injury in cornfields and gardens. Many of the native American sparrows are fine singers, and they are of great use in destroying insects and the seeds of harmful plants.
