Species of the Month

Introduction: One of the surest signs of spring is the return of the American robin, March’s Species of
the Month. From their cheerful morning song to the way they hop about your lawn, what’s not to love
about this little harbinger of better weather?

Scientific name: Turdus migratorius
Kingdom: Animalia (animals)
Class: Aves (birds)
Order: Passeriformes (perching birds)
Range: Southern Canada to southern Mexico
Habitat: Open grassy areas and open woodlands with dense shrubs
Lifespan: Average age 2 years
Diet: Berries, worms, insects
Predators: Snakes, squirrels, blue jays, crows, ravens: eggs only; snakes, hawks, house cats: adults only 
Conservation Status: Not listed as threatened or endangered, but protected under the Migratory Bird
Act.
Other Information: The gregarious, ubiquitous American robin is one of the first birds to begin nesting
in the spring. They start shortly after arrival, and may lay as many as three clutches of eggs. Each
clutch gets its own nest. The parents won’t start a new family until the old one has fledged the nest,
about two weeks after hatching. The young won’t become expert fliers for another two weeks after and
will be somewhat reliant on the parents until then.

Male robins are slightly larger than females. Unlike many other birds, male and female robins look
nearly identical. Females are slightly lighter in color. Juveniles have a speckled breast, rather than the
familiar reddish coloring.

Outside of breeding and nesting season, American robins typically feed and roost in large flocks. They
roost overnight in trees in dense woods or secluded areas. During spring and summer they are more
solitary. Watch them in your yard. When grounded, their motion is hop hop hop hop or run run run run
run stop run run run run run stop. When stopped they frequently cock their heads. They do this because
they are looking for worms or any danger. They must move the entire head because their eyes don’t
move like ours.
