Indigo Bunting Passerina cyanea can be seen all over Michigan during their migration in spring and fall and like to nest in a dense growth of shrubbery or weedy habitats between woods and old fields.
Similar in size to a goldfinch, the male Indigo buntings look blue with black wings, tail, and beak. The diffraction of light through their feathers makes them look blue. The females are a soft brown with brown streaks on the breast and a light throat. The young look similar to the female.
At certain times of the year I spot indigos at my feeders eating Nyger Thistle and the Wild Birds Unlimited No-Mess blend which has the sunflower chips, peanuts, and millet without the hulls. Some customers enjoy them all through breeding season because they have the right habitat.
These small bright birds make their way to Michigan from Central America during the spring, and settle in woodland edges and farmlands to nest in the spring and summer. While in Michigan, the birds live a solitary life defending their territory and hunting alone or with a mate.
The female does most of the feeding and caring for the young, while the male defends the nest against intruders. Once the young have fledged the males will teach them to forage, while the female is busy building a new nest for the next brood. Together each pair usually raise one or two broods before they head down south again to winter in huge flocks that forage together in the day and roost together at night.
Indigos like a variety of food, including small seeds, nuts, berries, insects, mosquitoes, flies, aphids, small spiders, buds, goldenrod, thistle, grasses, and herbs. At your feeders you should spot them eating your Safflower and Nyger thistle. You can also feed them apple slices, suet, millet, peanuts, or berries.
