On 7 October 1994, we collected an adult female Gray Silky-Flycatcher (Ptilogonys cinereus) at Arroyo El Medano, also known as Arroyo Cantamar, about 1.5 km northeast of the town of Cantamar, Baja California, Mexico(32°14'10" N, 116°54'40" W; elevation 15 m). This species has not been previously recorded in Baja California (Grinnell 1928; Wilbur 1987), and the nearest known resident population is located in southeastern Sonora (28°20' N; Phillips 1991), approximately 750 km from the site reported here.
