AMERICAN ROBIN (Tardus migratorius) 



The robin, with its cheery song, distinctive red-orange breast, and trusting 

 habits, is perhaps the best known and best loved of all our native song 

 birds. Because of its adaptability the robin thrives in almost any environ- 

 ment. In Yellowstone and Grand Teton the robin is one of the most abun- 

 dant breeding birds, breeding in virtually every environmental complex 

 below timberline. Robins which breed in developed areas of the parks are 

 as tame and trusting as the robins found in towns, city parks, and farm- 

 yards; however, the backcountry hiker will encounter a wild robin whose 

 temperament is more in keeping with its wild surroundings. The nest of 

 the robin is grass-lined and mud-wailed and the eggs are a beautiful 

 turquoise blue.
