3^6 Scott, Early Spring Notes from Southern Arizona. [October 



Aphelocoma sordida arizonae. Abundant up to the lower 

 edge of the pines, in the evergreen oak region. Breeding gen- 

 erally. 



Contopus pertinax. Common in the pines, and also found 

 a little below in the adjoining oaks. All of the specimens pro- 

 cured were males, and I do not think the females had arrived. 

 While the actions of the bird in a great measure resemble those 

 of Contopus borealis, in general appearance it is much more like 

 Contopus v/rens, and the song, which I heard continually during 

 my stay, is even more musical in tone than that of its last-named 

 smaller ally. I secured nine males during my stay and saw many 

 others. This was the only Flycatcher observed in the pine re- 

 gion, though not more than three miles away, and at an altitude 

 probably two thousand feet lower, several others ( Tyran?ius 

 voclferans T. verticalis, and 2Iyiarchus c/nerascens) were 

 very common. 



Phalaenoptilus nuttalli. Rather common throughout the 

 pine region, and abundant in the evergreen oak belt. I heard the 

 first birds of this year singing near my house on the evening of 

 February 27, and in a few days the birds were very common. 



Selasphorus rufus. Though I observed four or five Hum- 

 mingbirds, all of which I should refer to this species, well within 

 the pines, the only one in reality identified — a male in full plu- 

 mage — was at the lower pine limit on April 24. 



Picus villosus harrisi. Not common. Only a few noted 

 and a single male taken. Generally seen in pairs. 



Melanerpes formicivorus bairdi. Rather common, and ap- 

 parently mated or mating. 



Asyndesmus torquatus. But two observed in the pines, 

 though the birds were noticed commonly in the oak region dur- 

 ing the ascent and on the return. 



Colaptes mexicanus. Rather uncommon in pairs. Males 

 in full song. 



Buteo borealis calurus. The only Hawk observed, and not 

 common. Abundant at lower altitudes in the mesquite region, 

 where it begins to breed early in March. 



Cathartes aura. One taken at a high altitude, in the pines. 

 The onlv one seen.
