Distribution, Range and Migration

These birds are widely found throughout USA especially in states like Michigan, Ontario, Wisconsin and New Jersey.

They spend their winters in northwestern South America. Their summer range stretches across the eastern and mid western part of USA till southern part of Canada. Their migration route passes through Central America during the month of April and again in the month of October. These marvelous birds love to spend their winters in the lap of evergreen mountainous forests. They are amongst the few American song bird species that have evolved to migrate to other parts for breeding.

They arrive on the breeding grounds in large numbers during the month of May and begin to move towards south again in mid-summer. By October they are all set to fly southwards.


These birds are usually found in dense deciduous forests of oak, hickory, tulip trees, ash, pine and in wooded inhabited areas as well as parks.


Let us study the behavioral patterns of these vibrant birds.

  • These birds are solitary and secretive in nature spending most of their time at tree top canopies making it difficult to spot them.
  • When threatened, it mobs its predators by diving and swooping around them and calling simultaneously. Sometimes, they become quiet and observe their enemies (especially American Crows and Merlins) to hide.
  • They are monogamous by nature.
  • They keep their nest very clean and tidy. Any droppings on the nest are either swallowed or thrown away using their bill.
  • These birds are highly territorial on the breeding grounds and warn other males by singing frequently.
  • They join other mixed species of birds for foraging on wintering grounds.

Diet and Food

These birds are primarily insectivorous, feeding on insects like aphids, nut weevils, wood borers, ants, leaf beetles, cicadas, parasitic wasps, dragonflies, termites, caterpillars of gypsy moths and bees. They capture insects by leaning and grabbing while flying, beating them against branches to kill it.

They also feed on fruits like mulberries, wild fruits, huckleberries and June berries. However, spiders, certain earthworms, seeds and buds top the list of their food preferences.


These birds are excellent flyers with quick reflexes which helps them to catch and eat flying insects.

Calls and Song

Scarlet Tanager’s has a soft and croaky “chip-burrr” call. During the summer, its Robin-like song of rough notes “querit queer query querit queer” is heard in deciduous forests. The females reply to the male’s calls by singing in shorter but similar pattern. Their voice is, however, much softer and less coarse.

They call during territorial fights or if there is any existence of danger. It is followed by drooping wings and snapping of tails.

At dawn, male tanagers sing incessantly, mingling calls with songs. Females sing especially while gathering food or materials for building nests.


These birds have certain adaptive characteristics:

The bill of the Scarlet Tanager has a distinctive tooth-like structure on the cutting edge of the upper jawbone. This enables the bird to eat fruits and ariled seeds.


Short-eared owls, eastern screech owls, long-eared owls and merlins are some of the main predators of Scarlet tanager. Predators for eggs and nests include American crows, squirrels, blue jays, grackles, chipmunks as well as snakes.

Mating Season

The mating takes place from late April to mid May. These tanagers are sexually dimorphous. The male usually starts singing to attract the females on the breeding grounds.

The male sings in alternatively high and low pitch voice before performing its courtship displays from the lower branches of the trees. The male holds its wilted wings and separates the body while its neck is drawn out to exhibit the back. The male finally displays his brilliant color to the female birds.

When the female reacts positively and pairs are formed, then these monogamous pair goes on to build their nest and stay as one for a long time. Now after the mating is over, they look forward to build nest.


The tanagers prefer to build their nests in parks, deciduous forests, woodlands and suburban areas having large trees. The female then lays three to five pale bluish or green eggs which are delicately and boldly marked brownish. Female incubates the eggs all alone for around fourteen days.

Nesting Habits

The nests are built by the females in around two weeks. Located at around 5 to 75 feet above the ground, the nests require around a cup of twigs, grass and stems to build. The nests are built on horizontal branches. They make the nests in such a way that clear open flyways are accessible from adjoining trees to the nest. The saucer shaped nests are usually shallow.

During this nest building and incubation phase, the male is unable to assist female as its brightly colored plumage may draw enemies putting them in danger.
