end of Vancouver Island, Lusher took a juvenile male, one of the two 

 records for the island. M. F, Oilman (1937) reports "a pair of lazuli 

 buntings, August 20" in a list of "birds not regularly seen" in Death 

 Valley. Pulich saw one male on Aug. 14, 1952, opposite Fort Mohave, 

 Clarke County, Nev. 



In general, this species decreases in numbers in the northern part 

 of its range during August, and by the end of the month or early 

 September all are gone. Simultaneously they become more abundant 

 in the southern part of their range. E. C. Kinsey (letter, 1955) 

 states that "the males leave first on the southern migration, the 

 females and young following later. I have taken immatures of the 

 year as late as September 15. Indeed, we have some 20 records of 

 young lazulis trapped at Manor during the first 2 weeks of September." 

 At Boulder Beach, Nev., W. M. Pulich (letter, 1955) reports that in 

 1955 this species appeared about September 4, and on September 6 

 fu'st entered traps which had been in operation from August 21. 

 They continued to enter the traps until September 17, with September 

 9 the peak in numbers. A total of 22 were taken, with 11 repeats so 

 spaced as to suggest that no individual stayed in the vicinity more 

 than 4 days. 



In New Mexico along the Pecos River, H. W. Henshaw (1886) 

 collected a single male on August 8, the only one he saw in 3)^ months 

 between July 18 and October 28. In Arizona, H. S. Swarth (1904) 

 reports that this species reappears at a very early date in the Huachuca 

 Mountains. "* * * one was seen on July 22, 1902, and their numbers 

 increased rapidly throughout August. * * * In the fall the old males 

 were the first to appear, the females and young following later." 

 Oradually they move southward until all have left the United States 

 by the end of September or early October. Rarely, a few may winter 

 m southern Ai'izona. G. Monson and A. R. Phillips (1941) collected 

 two males at Patagonia in southwestern Arizona on Dec. 3, 1939, 

 the first winter record for the State. 



Winter. — Practically nothing has been recorded on the habits of 

 this species on its wintering grounds, nor have those who have seen 

 and collected it at this season been able to give me such information. 

 Robert T. Moore's earliest date of arrival on the wintering ground is 

 September 3. His collection includes two taken at Guirojqui, Sonora, 

 Mexico, on February 2 and 4, and winter-taken specimens, mostly 

 December and January, from Sinaloa and Durango south through 

 Jalisco and Michoacdn to Guerrero, from where he took one speci- 

 men on January 27. A. J. van Rossem (1945) reports them as 

 winter visitants in the tropical zone of southerly Sonora. R. B. 

 Lea and E. P. Edwards (1950) saw several in the undergrowth of the 

 pine woods of the Lake Patzcuaro region, Michoacdn, on Mar. 17,
