It is easy to take the warmth of summer when you’re decked out is such cool shades of blue! The Indigo Bunting is a bird of the summertime in eastern North America. This species that winters from southern Florida to northern South America arrives in the northeast in late May and early June. Indigo Buntings are consummate singers. Males seem to express their appreciation of our climate by singing from a tree branch for much of the time they are with us, often continuing their serenade well into the hottest part of the day. Interestingly, there are slight variations to the basic song that are regionally based and shared by males in a given “neighborhood.”
They say opposites attract. Male Indigo Buntings in their breeding plumage have spectacular blue hues with brown notes on their wings and tails. Females are brown with hints of blue on their shoulders, rump, and tail. Be sure to note the classic conical bill of a seed-eater on either sex.
While Indigo Buntings are migrating from their winter grounds to the northeast, they feed on the seeds of native grasses. As they arrive, they continue to consume seeds, often finding backyard seed tubes filled with nyjer and finch mixes. Once the temperatures have warmed sufficiently for an ample supply of insects to be present, they typically disappear from our feeders. Besides spiders, caterpillars, and larvae, summer foods include tree buds, young leaves, and various berries. Another favorite Indigo Bunting food may also be present in your lawn: dandelion seeds!
Rather than leaving your dandelions to go to seed, a better strategy for attracting Indigo Buntings, is to fill a nyjer tube feeder with Aspen Song® Finch Mix. This premium blend of fine-textured seeds should be a staple in your spring and summer bird feeding program.
Backyard hobbyists have a once a year opportunity to host Indigo Buntings. While the viewing is brief, it is certainly spectacular!
