'SSS.] Scott on the Biidsi of Arizona. TC 



This species I found quite commonh- as a migrant in the Catalinas, and 

 it breeds rather rarely in the same range at an altitude exceeding 4500 

 feet. They arrive late in March (Catalinas, 4000 feet), and are not very 

 common during the spring migration. A few are to be noted at a little 

 higher elevation all through the summer months, and in the earlv fall 

 their numbers are very appreciably augmented. The^' remain in this 

 same locality till about the first week in October. (For reference to their 

 occurrence in the pine forests of the Catalina Range, see Auk, Vol. II, 

 No. 4, p. 352, October, 18S5.) On June 15, 1S85, I took two fully fledged 

 young of this species in the Catalinas at a little above 4000 feet. They 

 are catalogued, " $ juv. 2809, '^ juv. 2810." 



[These two examples, and two others taken July 12, do not appear to differ 

 in color or markings from birds of the year killed in October. — J.A.A.] 



207. Dendroica townsendi. Townsend's Warbler. — Found only 

 as a migrant in the Pinal and Catalina Ranges. The following are the 

 records transcribed from my journal : 



"Mineral Creek, Gila Countj', altitude 5000 feet, took J, No. 153, No- 

 vember 2, 1S82. The only representative of this species observed here." 



"Catalinas, 4000 feet, September 8, 18S4, one seen, the first of the 

 fall migration. Same locality, September 28, 1884, took $ , No. 931, the 

 only one seen. September 29, took $ , No. 957, and saw several others 

 — this at about 3500 feet. Same locality, May 6, 1885, general arrival, 

 and the first seen this spring. They were quite common in the oak belt, 

 altitude a little over 5000 feet. Took four and saw several others." 



208. Dendroica occidentalis. Hermit Warbler. — Among the rarest 

 Warblers of the region apparently. I have met with it only on one occasion 

 — September 29, 1SS4, in the Catalina Range, altitude 350ofeet, — when I 

 took two, both males (Nos. 95S and 959), and saw two others. 



209. Seiurus noveboracensis notabilis. Grinnell's Water Thrush. — 

 In the Catalinas, at an altitude of about 3500 feet, on September 2, 

 1884, I took an adult female Water Thrush (No. 780), and on the following 

 day an adult male (No. 797), both of which I refer to this subspecies. These 

 are the only examples I have met with and I did not see any specimens in 

 Mr. Brown's collection. 



210. Geothlypis macgillivrayi. Macgillivray's Warbler. — A rather 

 common migrant, and a few probably breed in the Catalinas, as I have 

 taken young birds early in August. After the 9th of this month they 

 were not rare. They arrive early in May and remain till the last of Sep- 

 tember, the latest record I have being the 25th of that month. These 

 observations were made in the Catalina Range, altitude 4000 feet. Mr. 

 Brown regards it as a rather common migrant about Tucson, where I 

 also saw it late in April, 18S4, in numbers. 



211. Geothlypis trichas occidentalis. Western Yellow-throat. — "A 

 rather common migrant, and breeds about Tucson, but is not found in 

 winter at this point." {Herbert Bro-vii.) Mr. Brown also tells me that 

 it arrives in the vicinity of Tucson about the first week in March, and 

 remains in numbers late into October, and is occasionally seen in the 

 early part of November.
