i8&7-J Scott on the Birds of Arizona. ig 



fall record is September 2, from which time until about October 1 I 

 constantly met with it. In the pine forests of the Catalinas, though C. 

 pertinax was common late in April, I made no record of C. borealis. 



114. Contopus pertinax. Coues's Flycatcher. — Twice during my 

 long stay in the Catalinas I noticed or took this species near my house, 

 and this is the lowest altitude at which I am aware of its occurrence. My 

 records are "837. $ juv., 7 September, 1884."; "April 27, 18S5, one seen, 

 altitude 4000 feet." 



For detailed notes as to the occurrence of this species in the pine 

 forests of the Catalina Mountains, see my paper in 'The Auk' (Vol. II, 

 No. 4, October, 1885, p. 356), entitled "Early Spring Notes from the 

 Mountains of Southern Arizona." 



115. Contopus richardsoni. Western Wood Pewee. — The follow- 

 ing notes in regard to this species are all from the Santa Catalina Moun- 

 tains, though the bird doubtless occurs throughout the region under 

 consideration. The first noted in spring was April 27, 1885, when two 

 were seen and one other taken, at an altitude of 4500 feet. Became com- 

 mon May 10, 1SS5. The first nest was noted June 9, 1885; parent sitting 

 on three fresh eggs. 



In the fall I found it common in September up to the 29th, in 1S84, 

 when it was last seen. Two and occasionally three broods of from one 

 to three young are reared in this locality during the summer. 



116. Empidonax difncilis. Baird's Flycatcher. — I have taken this 

 species in the Catalina Mountains from June 2 to October 28. Most of the 

 specimens taken, however, were collected in September and October, 

 when it is not uncommon. 



117. Empidonax pusillus. Little Flycatcher. — The only speci- 

 mens of this species obtained are two, taken August 15, 1884, in the Cata- 

 lina Mountains ; one is an adult male, the other a young male. 



11S. Empidonax hammondi. Hammond's Flycatcher. — A spring 

 and fall migrant in the Catalina Mountains where all the specimens here 

 recorded were taken. The earliest notes of spring arrival which I have 

 are a single bird (No. 2024) taken March 31, 1885, at an altitude of 4000 

 feet. The arrival of the birds was general on the 7th of April, and the 

 last seen in spring were taken May 5 and 10, 1885. In fall I have taken 

 the birds at the same point from early in October until the 25th of that 

 month. 



119. Empidonax obscurus. Wright's Flycatcher. — Of the four 

 specimens of this species taken in the Catalina Mountains (altitude 3500 

 to 4500 feet) three were taken in May and the other on August 15. I 

 have no data on the distribution of this bird in other parts of Pinal 

 County. 



120. Pyrocephalus rubineus mexicanus. Vermilion Flycatcher. — 

 This was one of the more conspicuous and common species at Riverside 

 during the month of April, 1882, and was also noted there throughout the 

 summer. It is resident about Tucson, and also at Florence, and though 

 it is not common at either point during the winter, I have records of its
