90. Piranga hepatica. Hepatic Tanager.* — Common migrant about 

 Tucson, and tolerably common summer resident above 6000 feet in the 

 Catalinas. It has the song and sharp call of the Scarlet Tanager. April 

 29-Sei)tember 18. 



91. Piranga rubra cooperi. Cooper's Tanager. — A common breeder 

 along ditches in the Santa Cruz Valley. April 22-August 22. Its song is 

 far sweeter than that of the other tanagers. It has a purity which sug- 

 gests the Rose-breasted Grosbeak. The alarm note is also softer. 



92. Progne subis hesperia. Western Martin. — Very abundant about 

 Tucson in sinnmer, nesting in holes made by the Gila Woodpeckers and the 

 Flickers in the giant cacti. From August 1 to September 20 large flocks 

 were seen daily. 



93. Petrochelidon lunifrons. Cliff Swallow.** — A few seen at 

 Tucson the last of March. 



94. Iridoprocne bicolor. Tree Swallow. — Seen several times in 

 March and April in the valley. 



95. Tachycineta thalassina lepida. Violet-green Swallow. — Seen 

 in large flocks in spring, March 25 to April 8, and in the fall, September 8 

 in valley; abundant nester in the pines. 



96. Stelgidopteryx serripennis. Rough-winged Swallow. — By far 

 the most abundant breeding swallow about Tucson in 1909. Left (July 2) 

 after breeding. 



97. Lanivireo solitarius cassini. Cassin's Vireo.* — An uncommon 

 migrant along the river as well as in the mountains. 



98. Lanivireo solitarius plumbeus. Plumbeous Vireo.* — A frequent 

 migrant near Tucson; first seen April 6. "Fairly common breeder in the 

 mountains." (Lusk.) 



99. Vireo huttoni stephensi. Stephens's Vireo. — "Nests twice at 

 5000 feet in the Catalinas. First brood is out by May 1 and second by 

 July." (Lusk.) 



100. Vireo belli pusillus. Least Vireo. — Common summer resident 

 in valley. Song resembles that of the Yellow Warbler. 



101. Vermivora virginiae. Virginia's Warbler. — Nest found by Mr. 

 Lusk at 7500 feet in the Catalinas. 



102. Vermivora celata lutescens. Littescent Warbler. — Common 

 breeder throughout the region. I have found nests in the valley and Mr. 

 Lusk in the forests of the mountains. 



103. Peucedramus olivaceus. Olive Warbler.*** — Not a rare nester 

 in the higher reaches of the Catalinas. Nests found by Mr. Lusk. He 

 believes that the males do not attain the brightest coloration until at least 

 the third year. Also that the young males .sing only snatches of the 

 flowing song of the bright colored adults. 



104. Dendroica auduboni nigrifrons. Black-fronted Warbler.** — 

 Although it is auduboni which is so abundant in the lowlands, tliis is the 

 common resident of the tops of the mountains, where Mr. Lusk has taken 

 nests. Auduboni was seen in the lowland as late as the end of May and 

 doubtless nests not far distant.
