American robin (Turdus migratorius)
CONFIRMATION STATUS: Confirmed.
The American robin population in the eastern United States was depleted
in the early 2000s due to the epidemic spread of West Nile virus (intro-
duced into the United States through New York City in the late 1990s).
By 2004 the northern Virginia population of American robin was signifi-
cantly reduced. Fortunately, the disease seems to be less virluent to
American robins as compared to other birds; in particular, the American
crow (100% death rate for infected birds), a species that is found in the
same range throughout much of Virginia, has been more seriously inflicted
the the virus. Unfortunately, the American robin, once infected, lives
longer than other species, helping to spread the disease.

The American robin is a common occupant of residential areas during
the breeding season. In fall and winter, it can be found in large,
somewhat nomadic flocks in areas with lots of fruiting trees. The
very rare rufous-backed robin (southwestern United States) has a
rufous, not gray, back. The varied thrush has a dark band across its
breast and orange wing bars.
