Can you see why these brilliantly colored birds are nicknamed "blue canaries?" Common and widespread through late spring and summer all over eastern North America, Indigo buntings spend winters in South America. This male is in his summer colors, while the females are brown all year round. They sing their cheery song from dawn to dusk atop the tallest perch in sight, and if you are lucky they might stop by your bird feeder in spring or summer. Photo: Dawn Scranton
