may tarry en route between the two. Stephen S. Visher (1910) 

 states that leucophrys (now oriantha) is an abundant winter visitor 

 in Pima County, Arizona and that "they remain several weeks longer 

 than Z. gambeli feeding on the blackberry-like fruits of the mulberry. 

 Last seen June 8." Laurence M. Huey (1926) observed a flock of 

 fifty white-crowns (which I assume were oriantha) on May 22 at El 

 Rosario in Baja California. The following day only two were seen 

 and one collected, indicating that most had departed the previous 

 night. Joseph Grinnell and T. I. Storer (1924) state that what is 

 now called the mountain white-crowned sparrow is a summer visitant 

 to the Hudsonian Zone in the Yosemite region and that it passes 

 through the lower levels on both sides of the mountains during spring 

 migration. 



The earliest definite records of the arrival of the Hudsonian white-crown in 

 the Yosemite region are for May 10 (1916) * * * and for May 8 (1917) * * *. 

 Migration was still in progress on May 22 (1919), as a male bird in Yosemite 

 Valley on that date tarried only a short time before moving on. * * * Some 

 individuals continue in their summer haunts until the end of September, several 

 having been noted by us at Tuolumne Meadows on Sept. 29, 1915, but none 

 anywhere later than that date. 



Our highest record for the Hudsonian white-crowned sparrow was close to 

 11,000 feet altitude, in a patch of stunted willows in a draw between Mount 

 Gibbs and Mount Dana, July 29, 1915. 



Joseph Grinnell, Joseph Dixon and Jean M. Linsdale (1930) col- 

 lected white-crowned sparrows thought to be still on their breeding 

 grounds at Warner Creek in the Lassen Peak Region on Sept. 16, 

 1923 (elevation 8,000 feet). 



Eustace L. Sumner and Joseph S. Dixon (1953) give many records 

 of oriantha in Sequoia National Park. In 1942 the first spring arrival 

 in the park was on May 12 after a snowstorm at Lewis Creek. In 

 1934 three white-crowned sparrows were seen (one was taken) in a 

 willow thicket at 9,700 feet near Gallats Lake on the Kern-Kaweah 

 River, June 7. That same year six were seen at Kaweah Gap, at 

 10,700 feet elevation, on June 16; one of these (a female parent, no. 

 9090 in the Dixon collection) and a nest with four fresh eggs were 

 collected. The fall records are as follows: On Sept. 20, 1933, when 

 the willows were turning yellow at Heather Lake, just one bird, an 

 immature, was present; the adults apparently had left on their fall 

 migration. In 1940, one was found in Deadman Canyon on Septem- 

 ber 22 (they were no longer common in the vicinity) ; on September 24 

 one was seen at Scaffold Meadow. Two white-crowned sparrows 

 noted at Giant Forest on Oct. 3, 1934, were evidently fall migrants 

 from higher regions, as this species had not been there during the 

 summer; two immatures were seen just below Tharp's Rock on Octo-
