Observations of a Gray Whale Birth
Observations of births of gray whales (Eschrichtius robustus) have been made by Balcomb (1974), Leatherwood and Beach (1975) and Storro-Patterson and Kipping (1977). We report a fourth observation of a gray whale birth; this from Estero de la Soledad in the Bahia Magdalena complex, Baja California Sur, Mex- ico (Fig. 1). We learned from Storro-Patterson that both his (1977) and Balcomb's (1974) observations were also made in this area; Storro-Patterson' s at a location near the cannery at Puerto Adolfo Lopez Mateos, and Balcomb's nearby to the north (per. coram.). Leatherwood 's observations were made in the open sea off Mission Bay, San Diego.
