i88S.] Scott on the Birds of Arizona. 7 1 



iSi. Progne subis. Purple Martin. — Observed rather uncommonly 

 about Tucson. 



182. Petrochelidon lunifrons. Cliff Swallow. — Observed in num- 

 bers about Riverside in April, 1SS2. 



183. Chelidon erythrogaster. Barn Swallow. — Common migrant 

 throughout the region, and breeds rather sparingly in the Catalinas, at 

 an altitude of 5000 feet. The species seems much more abundant as a 

 fiill than as a spring migrant. On October 12, 1SS4, they were abundant 

 in the Catalinas, at an altitude of 4000 feet. 



1S4. Tachycineta bicolor. Tree Swallow. — Observed only about 

 Tucson in early spring. They were noted in small numbers on March 

 10, 1SS6. Mr. Herbert Brown tells me he regards the species as rare. 



185- Tachycineta thalassina. Violet-green Swallow. — In the 

 Catalinas this is the commonest of the Swallows, but, curiouslj', at the 

 lower altitudes (4000 feet) in the spring it is rare or does not occur. In 

 the spring of 1SS5 I found it common in late April on the summit of the 

 mountains in the pine woods, but though I had looked for it carefully 

 all the preceding six weeks at the altitude of my house I only saw a 

 single individual, on March 14. In the late summer and fall from 

 August 15 till October 7, it was common in the region near my house. 

 It probably breeds in the pines of the Catalinas in numbers (see Auk, 

 Vol. II, No 4, p. 354)- 



186. Clivicola riparia. Bank Swallow. — "Breeds about Fort Lowell" 

 (^Herbert Bro'Mn). I have no records of its occurrence except at this 

 point, where I saw it in May and June, 1SS4. 



187. Stelgidopteryx serripennis. Rough-winged Swallow. — "Rather 

 rare about Tucson, arriving about the middle of March" (^Herbert Brotvn). 

 Mr. Brown very kindly allowed me to examine several specimens of this 

 species in his collection, taken near Tucson. 



188. Ampelis cedrorum. Cedar Waxwing. — Mr. Brown has speci- 

 mens of this species in his collection, taken by Mr. Nelson near Tucson, 

 in May and June. I have no notes of its occurrence at other points in the 

 region under consideration. 



189. Phainopepla nitens. Phainofepla. — This species has been dis- 

 cussed at some length (see Auk, Vol. 11, No. 3, pp. 242-246, July, 18S5, 

 paper on 'Breeding of Some Arizona Birds'), and thei-e is little to add 

 here. I met with it at every point visited by me up to an altitude of about 

 5000 feet. It is migratory, except about Tucson and in the region to the 

 southward, and here only winters in small numbers. Itappai-ently breeds 

 throughout its range, raising at least two broods and probably three. In 

 the Catalinas, at 4000 feet, my earliest spring record is April 25, and I 

 have notes of their occurrence here till November. 



190. Lanius ludovicianus excubitorides. White-rumped Shrike. — 

 Resident up to an altitude of about 5500 feet. Rather common throughout 

 the year about Tucson, and observed in suitable localities throughout the 

 area under consideration. In the Catalinas (altitude 3700 feet), a nest of 

 this species, taken April i, 1S85, contained five eggs almost ready to be 

 hatched. I think only one brood is raised here.
