This endangered species is threatened by habitat destruction, and in some parts of its shrinking range more than 90% of the nests are parasitized by cowbirds.

The deep, cup-like nest is hung by its rim in the fork of a small branch in a short tree, and it is constructed of grass, leaves and spider silk.

Cowbirds often use this towhee as a host for their eggs and young.
