Indigo Bunting vs Blue Grosbeak

Coloration and marking:

The Indigo Bunting is a small songbird notable for its vibrant blue plumage. The male of the species is particularly striking, with a deep blue body, and greyish-black on the wings and tail.

The underpart of the wings and tail are white which can be seen when they make a flight.

They also have a very small amount of black near the base of the bill but not nearly to the degree that the Blue Grosbeak does. Whereas females are brown from head to tail with a blue-black wing bar and tail.

The Blue Grosbeak is a small bird with a big voice. They have blue plumage and distinctive rusty and black wing bars. They also have black masks near the base of the bill going over the eye that the Indigo Bunting lacks. Whereas the females are brown from head to tail and lack the blue of the male, but still have the same rust-colored wings.


The average length of Indigo bunting is 12-13 cm with a wingspan of 20-23 cm.

The average length of a Blue Grosbeak is 14-19 cm and the wingspan is from 26-29cm 


These small songbirds are most commonly found in forest edges and open woodlands, where they build their nests. However, they can also be found in fields, gardens, as well as in feeders. They are attracted to areas with dense vegetation, as this provides them with plenty of hiding places.

They are found in a variety of habitats, including woodlands, fields, and edges of forests, also commonly seen near streams or other bodies of water.


Indigo Bunting loves to eat various seeds, fruits, and insects. In the spring and summer, they primarily eat insects including spiders, millipedes, and snails. In the fall and winter, when insects are scarce, they switch to a diet of seeds and berries. The favorite seeds come from trees in the sunflower family, such as black-eyed Susans and coneflower. And in the winter, when other food is scarce, they will even eat poison ivy berries.

In spring and summer, they feast on insects such as beetles, grasshoppers, and caterpillars. They also enjoy munching on dragonflies, mayflies, and crickets. During the fall and winter months, when insects are harder to come by, they turn to seeds and berries. Their favorite fruits include grapes, cherries, sumac berries, and bayberries.


Nesting takes place from late May through early July. These birds nest in trees or shrubs, often close to the ground. Female lays 3-5 eggs, which are pale blue with dark spots. 

Blue Grosbeaks typically start building their nests in early May. The female will weave a cup-shaped nest out of grass, leaves, and twigs, which she will then line with hair or fur. She will usually lay 3-5 eggs, which are pale blue to white. The breeding season for this species typically lasts from May to August.


If you’re trying to attract Indigo Bunting to your backyard, here are a few tips: Plant native plants and bushes, as this will provide food and shelter for the birds. Put up a birdbath or a small fountain, as the birds will appreciate having access to water. Put seeds, berries, and fruits in the feeder which they like the most.

Spring and fall are the best times of year for these birds to see them at the backyard feeder, although they may visit the birdfeeder at any time and anywhere within their range during migration. If a Blue grosbeak does stop by at your feeder, serve its favorite food like sunflower seed chips or millets. And then enjoy watching them for as long as it stays.

Cool facts:

  • The song of these birds is one of the most distinctive sounds of summertime.
