 common among the scrub oaks; and three taken by Nelson, July 1 and 5, 1884, 

 at Gardner's Ranch. Found by Swartli, in June, 1903, in the oaks in the lower 

 l)art of the range. One was taken by Bailey, October 28, 1913. 



One was taken by Taylor, January 16, 1923, at Rosemont (5,000 feet), 

 when it was in the neighborhood of a flock of Bush-Tits ; and another, February 

 10, from an oak on a sidehill near Gardner's Ranch, when "it was travelling

Vireo beliii pusillus. Least Vireo"' 



Taken by Steplieiis in l.SSl, near Tucson in thickets of mesquite, and a few 

 found ))y Swarth in the lower part of the range and in the brush out (m the 

 mesa. The first seen by us were on March 27, 28, and 29, 1921, and the jerked- 

 out song of the White-eyed type — something like chkkortj, chickorij, rhce'-ah — 

 was heard from then on until our dei)arture on May 6, when the birds were 

 going about in pairs. While hunting mainly inside the mesquite thickets, they 

 occasionally came out in view, flipping about with a good deal of tail motion. 

 One was taken on April 16, 1921, when its stomach contained small green seeds 

 and insects. 



Vermivora luciae. Lucy Warbler 



One was taken by Stephens, May 19, 1881, in Madera Canyon, and a juve- 

 nile was taken by Nelson, July 11, 1884, at Gardner's Ranch. Both adults and 

 juveniles were taken by Swarth in the latter half of June, 1903, and it was found 

 breeding abundantly in the mouth of Madera Canyon and in the ravine beloAV. 

 They were first seen by us April 5 and 13, 1921, near 4,000 feet, after which 

 they were frequently found in the mesquites. One seen on May 2, in the mistle- 

 toe of a mesquite top was acting as if hunting for a nesting place. On April 22, 

 one was singing loudly among the freshly green meVKpiites whose tassels were 

 beginning to yellow. It had a characteristic warbler song — ivliec-te,:, whee-tee, 

 ■u-hce-tee, whee-tee, ivhee-tee, whee-tee, ivhee-tee, whee-tee, whee-tee, wheet, and its 

 call was a faint chip. As it sang, its white throat and breast held up in the 

 light made a good mark, but the brown of its head was hard to see unless it 

 leaned over, parting its feathers in the light, and its brown rump patch was 

 hard to catch unless it leaned over preening its feathers or dropped down 

 spreading its wings and tail. In the main it hunted (|uietly. stretching its 

 neck as it reached after insects.
