Birds of the Region about Needles, California

I• THE spring of 1905, while engaged in field work for the United States Biological Survey, I spent some weeks in the vicinity of the Colorado River near the point where California, Nevada, and Arizona meet.The region is interesting from an ornithological point of view as little work has been done there since the days when Fort Mohave was a military post2 Arriving in the region from the west I spent from April 10 to 16 at Goffs (Blake postoffice), California, a station on the Santa F6 railroad between Bagdad and Needles and about twenty-five miles west of the Colorado River.The territory surrounding Goffs is extreme desert, a series of bare rocky hills and sandy fiats with no trees whatever except a few scrubby tree yuccas about the basqs of the hills.The fiat districts are partly covered with a growth of the creosote bush (Covillea tridentata) and other desert shrubs, which are especially common and of greater size along the numerous dry washes; it was here that most of the birds were found.On April 16 I moved east to Needles, a small town on the California bank of the Colorado River, where collecting was carried on until May 1. Two days were then spent on the opposite side in Mohave County, Arizona.On May 6, in company with a Mohave Indian, I went into camp in the low bottomlands of the California side ten miles above Needles.May 17 we moved camp to Twin Lakes, half a mile below the California-Nevada line, from which point excursions were made up the west bank of the river into southern Nevada to extend the known ranges of various species into that State.On the 25th I moved across the river to • In the summer of 1902 Mr. F. Stephens collected in the Providence Mountains, about Needles, and at other points along the river, also in the interests of the Biological Survey, and published the results of his bird work, an interesting and valuable list, in ' The Condor,' Vol, V, Nos. 3 and 4, 1903.Vol.XXV] HOLL•S?ER, Birds of the Region about Needles, Cal.
