Canyon Towhees (Pipilo fuscus) normally nest in trees, shrubs, and cacti. I found a nest on the ground under an octagonal road sign in Santa Fe County, New Mexico, on 14 May 2001. No young were fledged, but the eggs were incubated for ≥10 days. Additional records of Canyon Towhee nests in a building and an enclosed trailer are indicative of a plasticity in their nest site selection process that led to use of this unusual nest site.
