Unusual nest sites for southwestern Willow Flycatchers

Stoleson, Scott H.; Finch, Deborah M. 1999. Unusual nest sites for southwestern Willow Flycatchers. Wilson Bulletin. 111(4): 574-575.

The endangered southwestern Willow Flycatcher (Empidonax traillii extimus) is an obligate riparian species that typically nests in willow (Salix spp.) thickets or other dense, shrubby habitats. We report on the first nests in Arizona sycamore (Platanus wrightii) and in a climbing rose vine (Rosa multiflora). Although these nests were located in novel substrates, they were typical for the species in being supported by multiple small stems and in having a dense canopy cover. We suggest that nest substrate preferences of Willow Flycatchers in the Southwest may be broader than generally considered.
