Aechmophorus Occidentalis in Lower California in Summer
Aechmophorus occldentalis in Lower California in Summer
There is apparently no certain breeding record for Aechmophorus occidentalis south of the United States, and in fact its nesting in the extreme southwestern corner of this country is largely inferential. It is known to spend the summer at Tulare Lake, and also in suitable places near San Diego, California, but there is no instance of the actual finding of the nest in either of these localities. In this connection it may be of interest to record two specimens of this species collected by Mr. L. J. Goldman of the Biological Survey in June, 1916, at Volcano Lake, northeastern Lower California. These are now, respectively, no. 259881, U. S. Nat. Mus., taken June 9, 1916, and no. 259882, U. S. Nat. Mus., taken June 10, 1916. Mr. Goldman reports that this species was common from May 1 to June 11 (when he left the region) in the delta of the Colorado River. He says that they moved principally in pairs, but he was unsuccessful in finding a nest.
