About the house wren

A plain brown bird with an effervescent voice, the House Wren is a common backyard bird over nearly the entire Western Hemisphere. Listen for its rush-and-jumble song in summer and you’ll find this species zipping through shrubs and low tree branches, snatching at insects. House Wrens will gladly use nestboxes, or you may find their twig-filled nests in old cans, boots, or boxes lying around in your garage

Migration

  • Bird migration is a seasonal journey that happens twice each year. Some bird species migrate but not all do. Birds that migrate are called migratory birds, birds that do not are called resident birds.





  • Birds migrate in search of food. Food is abundant in warm, sunny places and nearly absent in dark, snowy locations. What's more, food is more plentiful in places with longer days than nights and long days give birds more time to hunt for food.





  • Birds get their cue from nature. But it is the change in daylight hours rather than the change in weather that spurs birds to fatten up for the long flight ahead. Weather can be unpredictable, the number of daylight hours changes in the same way each year.
