The Vaux’s Swift (Chaetura vauxi) is a little known and uncommon bird in northeastern Oregon. These migratory birds arrive there in early May and leave in September (Gabrielson and Jewett 1970) and are often seen in forests or towns during migration. Nests of this species most often have been reported to be in chimneys (Finley and Finley 1924, Davis 1937, Bent 1940, Griffee 1961, Baldwin and Hunter 1963, Thompson 1977), probably because such nests are more conspicuous and more easily located than those in hollow trees. Only four Vaux’s Swift nests in natural conditions in hollow trees have been reported in the literature (Taylor 1905, Baldwin and Zaczkowski 1963). Baldwin and Zaczkowski (1963) located three nests in hollow live Western Hemlocks (Tsuga heterophylla) with broken tops in Glacier National Park. Manuwal and Huff (1987) found Vaux’s Swifts in spring associated most strongly with old-growth stands in Douglas-fir (Pseudotsuga menziesii) forests of the Washington Cascade Range.
