Get to Know Blue Grosbeaks and How to Attract Them

Blue grosbeaks are as gorgeous as they are uncommon. Here's where you can find them and tips to attract them to your backyard.

Any sighting of a blue grosbeak is a cause for celebration, because these beautiful birds just aren’t that common and they can be difficult to attract. Although their nesting range covers most of the lower half of the country, spotting one is a rare treat.

“Most people see them only fleetingly during spring migration,” says Bubba Scales, who owns Wild Birds Unlimited in Gainesville, Florida. Your best bet may be a migratory hotspot.


These blue birds are sometimes mistaken for indigo buntings, another blue Neotropical migrant that arrives at feeders in spring. Warm brown wingbars and a huge bill set blue grosbeaks apart. The female is tawny brown.

How to Attract Blue Grosbeaks

Blue grosbeaks may visit backyards anywhere within their range during migration. If a blue grosbeak does grace your feeder, take Bubba’s advice and serve its favorite food. “Number one is sunflower seed chips!” he says, along with whole sunflower seeds and millet. Then enjoy the visit of this uncommon bird for as long as it stays.


Meaty grasshoppers make up the biggest part of this grosbeak’s diet, bolstered by other insects and seeds, which are plentiful near the nesting sites. Still, often only a single pair of grosbeaks lays claim to a large field.

Nesting Habits

During the breeding season, they aren’t backyard birds—unless your backyard includes acres of the shrub-dotted field habitat this species seeks. Bubba, a self-described bird nerd, has feeders on his 10-acre property where he enjoys filming the birds. “Blue grosbeaks visited this feeder every day for four months!” he says.

Nesting season lasts all summer because blue grosbeaks often raise two broods. Look for male birds singing their musical warbles from utility wires or the tops of small trees. The small nest, often utilizing snakeskins, is built just a few feet off the ground in a bush, briar patch or tangle of vines. Up to five nestlings may cozy up in the little cup. Here’s how to safely observe nesting birds.

Why Are They Uncommon?

No one knows why these beautiful birds aren’t more abundant. In 1834, John James Audubon wrote in The Birds of America, “Although this sweet songster spends the spring and summer in our southern states, it must be considered as a rather scarce bird there.”

In fact, the Cornell Lab of Ornithology reports that the blue grosbeak is so scarce that virtually all aspects of its biology are poorly known. But unlike some bird species, blue grosbeaks did not experience a decline in population in the last 50 years. There may be even more of these birds around today.

So next time you see a blue grosbeak in the brush along roadsides or in old fields, savor the moment!
