About the Blue Grosbeak

The Blue Grosbeak is in the same family as the Northern Cardinal and a native to North America. They are medium-sized and seed-eating birds found all year round in the southern parts of North America. Most of their activities including breeding take place in the southern regions but as the decades go by, the bird is said to be moving its breeding range towards the north. Their overall population is stable and their numbers are increasing steadily.

They are migratory birds often moving south to Central America and a few towards the northern regions of North America.

Description and Identification

These stocky songbirds have large, triangular bills that seem to cover the entire face of the
birds, from the throat till the forehead. Both sexes are similar in size and range from 5.9 –
6.3 inches, with a wingspan of 11 inches. They exhibit sexual dimorphism through the
colours of their plumages. Adult males have deep, rich blue plumages with a small black
mask in front of the eyes. They also have chestnut wingbars and black-and-silver beaks.
Females are rich cinnamon-brown with the colour being the deepest on the head. Their
underparts are pale, and their tails are bluish. Immature Blue Grosbeaks resemble the
females in the colouring of the plumages.

Blue Grosbeak Color Pattern

The male is nearly entirely deep blue while its counterpart is cinnamon brown. Their large deep bill and double wing bars are what distinguishes them from other types of birds in the same family especially the Indigo Bunting which almost looks similar.

Blue Grosbeak Size

They are medium-sized birds with lengths ranging between 14-19cm and a wingspan from 26-29cm. Their weight ranges from 26-31.5g

Blue Grosbeak Behavior

The male Blue Grosbeak normally arrives at the breeding grounds first early in the season to form feeding flocks before the females arrive. The bird is monogamous and each pair can raise two broods in a single breeding season. Once they nest, the birds create a territory spanning between 2-20 acres to protect their nests from predators. When the eggs have hatched, they tend to reduce their territory.

Both the young and adult Blue Grosbeak gather in flocks to feed in grasslands, grain fields, and rice fields before migrating to other grounds for the winter season.

What Blue Grosbeak Eat

Blue Grosbeaks mainly feed on insects like grasshoppers and crickets, but can also eat
other invertebrates like snails, beetles, cicadas, treehoppers, and caterpillars. They also
incorporate a significant amount of plant matter into their diets, including the seeds of wild
and cultivated grains like wheat, oats, rice, corn, and alfalfa. They find their prey by hovering
over foliage and gleaning food from it, by catching flying insects from a perch, or even by
hunting the insects on the ground. These birds have been observed to prepare an insect
before feeding it to their nestlings for consumption, mainly by removing the head, wings, and
most of the legs.

Apart from insects, they feed on seeds and invertebrates like snails and slugs. Insects include beetles, caterpillars, treehoppers and cicadas. Seeds comprise alfalfa, corn, rice, oats, wheat, and others.

Where Blue Grosbeaks Live

Blue Grosbeaks breed in tangled vine and shrub habitats across southern North America,
ranging from New Jersey in the east, across the central United States, and into central California
in the west. They are generally found in old fields, forest edges, transmission-line corridors,
hedgerows, stream edges, deserts, mesquite savannas, salt cedar forests, and southern
pine forests. They opt for habitats that include small numbers of tree species with little
canopy coverage and low shrub densities. Their wintering habitats in Mexico and Central
America are also centered around shrubby habitats as far south as Panama. The native
communities in Mexico and Central America tend to prefer dry tropical forests and the edges
of other woodlands.

Blue Grosbeak like nesting in shrubs and thickets close to open or semi-open grounds. Breeding happens in dense entangled and low growth vine and shrub habitats. This extends from New Jersey, Central California all the way to North Dakota in the United States.

Range and Migration

Blue Grosbeaks are North American passerine birds that are mainly found breeding along with
the southern United States and northern Mexico. They are present on both coasts as well as the
dry desert areas in the southern United States during breeding. In the winters, these birds
migrate over the Gulf of Mexico and either continue southwards into Central America or
begin heading westwards across Mexico. A small population that resides in Mexico
throughout the year is also present.

Blue Grosbeak Lifecycle

Females can lay between 3-5 eggs and incubate them for 11-12 days when they hatch. The young ones leave the nest 10 days after they have hatched. Adults live to approximately 5 years.

Blue Grosbeak Nesting

The nests are built by females near open spaces or roads and are placed relatively low in
shrubs, trees, briars, or vines usually between 3 – 10 feet above the ground. On rare
occasions, nests can be made up to 25 feet high. The nests are compact and are an open
cup of twigs, weeds, rootlets, leaves, snakeskin, or strips of bark. Although the nest
construction is done by the females, the males sometimes aid in gathering materials. Odd
materials picked up from urban areas can also be used, such as paper, strings, or rags. The
inner cup of the nest is lined with fine grass, rootlets, and animal hair. Females have 1 – 2
broods each season, with the average size of each clutch ranging from 3 – 5 eggs.
