?2 Scott on the Birds of Arizona. [January 



191. Vireo gilvus [swainsoni. Western] Warbling Vireo. — Com- 

 mon spring and fall migrant, and a few breed in the Catalinas at as 

 low an altitude as 3500 feet. All mj notes in regard to the species were 

 made in the Catalinas, which is the only point where I have met with it. 

 Mr. Brown has found it as a migrant about Tucson. In the Catalinas, al- 

 titude about 4000 feet, it arrives about the middle of April and remains 

 until about October i, being most common during the first two weeks of 

 September. In 18S5, on June 9, I took a nest of this species near my 

 house, which contained two eggs nearly ready to hatch. The nest was 

 similar to that of the species in the East in every way ( $ parent. No. 2779). 

 For an account of the occurrence of this species in the pine region of the 

 Catalinas, see Auk, Vol. II, No. 4, p. 354, October, 1885. 



[A series of upward of twenty specimens of the Western Warbling Vireo 

 in Mr. Scott's collection makes evident the propriety of restoring this form 

 to formal recognition in our nomenclature, as Mr. Ridgway has recently 

 done in his 'Manual' (p. 471). The characters of smaller size, slenderer 

 bill, and more olivaceous coloring below are well borne out by the series 

 before me.— J. A. A.] 



192. Vireo solitarius cassinii. Cassin's Vireo. — All the data in regard 

 to this subspecies were collected in the Santa Catalinas, altitude 4000 feet 

 and above. My notes indicate this to be a rather uncommon spring and 

 fall migrant. Observed in spring from April 18 to May 15. 



[Of twelve specimens of this subspecies in Mr. Scott's collection seven 

 were taken in April and May (April 6 to May 10), and five in September 

 and October (Sept. 10 to Oct. 7) , indicating, as Mr. Scott says, that it occurs 

 merely as a spring and fall migrant. The fall specimens, as would be ex- 

 pected, are much more olivaceous than those taken in spring. — ^J. A. A.] 



193. Vireo solitarius plumbeus. Plumbeous Vireo. — All my expe- 

 rience with this subspecies was obtained in the same locality as the 



ast, where it had about the same distribution and time of spring arrival, 

 except that it was much commoner, and particularly so in the late summer 

 and early fall months. That it breeds at this point cannot be doubted, 

 though at an altitude in the mountains greater than 7000 feet, for I have 

 met with old birds in worn plumage as early as the middle of July. I also 

 took a single example of the species in the pine woods of Mount Rice, 

 Santa Catalinas, altitude 10,000 feet, April 30, 1885 (No. 2347, $). 



[Mr. Scott's sixteen specimens of the Plumbeous Vireo were all but 

 three taken in May, the earliest date being April 30, and the latest dates 

 July 17 and 19. The July specimens are in exceedingly worn plumage. Of 

 the thirteen May specimens, about one half were taken during the first 

 week, and the remainder during the last week of this month (May 23-30) ; 

 and the contrast between the condition of the plumage in the two series is 

 striking, through the much more abraded state of the feathers in the birds 

 taken near the close of the month, indicating that the birds were probably 

 summer residents and breeding. — J. A. A.] 



194. Vireo huttoni Stephens!. Stephens's Vireo. — The only speci- 

 mens of this subspecies that have come under my observation are the two
