 American
Robin
Our largest thrush (approximately 10 inches in length),
the American Robin is found throughout North America,
from extreme northern Canada and as far south as
Guatemala. This common and well-known bird is noted for
its habit of feeding in lawns where it finds earthworms
(by sight, not sound), and for its cheery voice. Robins
are often one of the first birds to sing in the morning,
singing long choruses of rhythmic paired phrases of two
or three syllables that alternately rise and fall in
pitch. The dawn singing is reprised at dusk and
occasionally throughout the day.

Robin Range Map
Once breeding season is over, the sweet-singing and
familiar robin of our backyards becomes more furtive and
shy. Large nomadic flocks form and range over the
countryside in search of berries such as mulberry, sumac,
grape, viburnum, and cedar, as they shift from their
breeding season diet of insects and earthworms to become
wholly vegetarian. By September, many are moving south
from the northern parts of the eastern half of the
country to winter with southern residents in the Middle
Atlantic and Gulf states. In the West, Robins wander
broadly in search of food and move generally to areas of
lower altitude. But some linger as far north as Canada
when food supplies are adequate, so the first robin you
see in spring may not have come from too far away.
Particularly in the South, where gunners could easily
harvest birds from dense wintering flocks, robins were
once widely hunted for food. Many were sent to markets
where the fat and juicy flesh was held in high regard. In
general, however, the robin has benefited from its
association with humans. As modern civilization advanced
into the plains, the planting of trees and the
construction of buildings provided the robin with
platforms for their large, not-easily-concealed nests,
and their range has since expanded. Similarly, in the
arid West, irrigation and suburban lawns have provided
the equivalent of moist grassland where robins find food
for nestlings.
Adults are gray brown above, with a darker head and tail.
The bill is bright yellow; the chin and throat are white,
with black vertical striping on the throat. Surrounding
the dark eye are white orbital markings. The breast is
brick red and the belly is white. In most eastern birds
the tail has white corners. Females are somewhat more
dull in color; the upperparts are lighter and more brown
in color; the head is not so black and thus provides less
contrast with the back; and the breast is paler, often
edged with white.
The common race of robins found throughout most of the
West tends to be more pale and lacks the white outer
corners of the tail. Robins of the humid Northern Pacific
coastal areas and those from Newfoundland tend to be very
dark.
Juveniles are dark on top, much like the adult plumage,
but the feathers of the back, upper wings, and rump have
streaks of white and blackish tips giving the upperparts
a speckled appearance. The cinnamon coloring of the
breast is overlaid with conspicuous black spots. There is
much individual variation in the cinnamon color of the
underparts: some juveniles are largely white underneath.
This plumage is molted sometime between August and
October, depending on when the individual hatched. Both
sexes look alike in juvenal plumage.
