With a very small total distribution, Abert’s
Towhee is a sedentary species that lives in dense brush and
woodlands along rivers and streams in the Sonoran Desert of
Arizona, with small extensions into surrounding states and
into a small portion of northern Mexico.
This large, plain towhee spends most of
the day on the ground, foraging for insects and seeds, or
perching in low shrubs or branches; its flights are usually
short and low. Rain during its March to September breeding
season brings about a peak in breeding within two weeks. Ranging
as high as 1300m, it prefers streamside habitat in brushy
understory of cottonwood-willow and mesquite bosques but has
adapted to some urban and shrubland habitats created by humans,
such as exotic shrubs along irrigation ditches. It is found
in exotic salt cedar in the lower Colorado River valley.
Since few breeding bird surveys cover its
habitat, population trends are unknown, but some estimates
are that its population has declined by as much as 50%, due
to habitat loss. Protection and restoration of riparian and
streamside habitats is necessary for the long-term health
of its populations; once cattle were removed from the San
Pedro Riparian National Conservation Area, the bird’s
populations there increased dramatically. Measures to benefit
the endangered southwestern Willow Flycatcher will also benefit
the towhee.
