On the morning of 13 December 1969 I observed a Warbling Vireo (Vireo gilvus) in the back yard of my home on Canon Drive in Santa Barbara, Santa Barbara County, California. The bird was observed regularly between this date and 12 March 1970, and was photographed (fig. 1). The bird was frequenting the magnolia and oak trees as well as several elderberry bushes situated in my yard, which is located near a creek edged with many oak trees and a few sycamore trees together with much cultivated shrubbery.
