Indigo Bunting (Passerina cyanea)
Above and below: A migrant Indigo Bunting stops to refuel in our yard in Pasadena, Maryland (5/2/2012). Plumage and molt details make this a second-year (SY) male, which means he was born last summer. Since then he traveled roughly 2,000 miles (each way) to winter in Central America or the Caribbean. Awesome.
