These Indigo Buntings are of two ages- the right male bird is a second-year bird (SY) (hatched last summer) and the male on the left is an after-second year (ASY). Note the primary coverts on the left bird are black feathers edged with blue and the right bird the coverts are brown retaining his immature feathers. We have caught SY males that have looked like the left bird except the primary coverts were brown so just because they are blue does not make them an adult ASY male. You can usually pick this coloration contrast using binoculars. Next time take a closer look when admiring an Indigo Bunting to see if it is an SY or ASY male. Females have similar traits with the primary covert coloration for each age class however it is hard to distinguish it in the field. Female SY primary coverts are brown edged brown and adult ASY females have brown coverts edged with blue. It is subtle coloration not a bright blue as the male.
Enjoy the beauty of this male Bay-breasted Warbler.
