(78.) ClNCLUS MEXICANDS SwainSOU. 



The known range of this species includes Arizona. 



SAXICOLID^E. 



79. Sialia mexicana Swainson. 



Permanent resident. Exceedingly abundant. In its familiarity and other 

 habits exactly replaces S. sialis of the east. 



Specimens vary in every conceivable degree between the dullest colored 

 young female and the high plumaged spring male. In immature plumage 

 some examples much resemble S. artica ; but there is always discernible a 

 dorsal patch somewhat differently colored from the rest of the upper parts. 

 The shade of blue differs in equally mature males, being sometimes of a pur- 

 plish tint, and rarely the blue so invades and interrupts the dorsal chestnut as 

 to render the boundaries of the latter quite undefinable. 



80. Sialia arctica Swainson. 



Rather uncommon. Noticed only late in the autumn and in the winter ; 

 not observed to breed at Fort Whipple, and I think it is there chiefly a winter 

 visitant. Has been taken as far South as Fort Yuma. Audubon s figure of 

 the female is quite incorrect. The species differs conspicuously from mexi- 

 cana in its habits. 



SYLVUDJE. 



81. Regulds calendulas Licht. 



Exceedingly abundant ; migrant. In spring, from third week in March to 

 second week in May. In autumn, from latter part of September to November. 

 A few probably breed in the neighboring mountains. The species remains in 

 abundance in the Colorado Valley during the winter, at least as high as Mo- 

 jave. 



82. Regulds satrapds Licht. 



Has been taken in the Territory, though I have myself never met with it.

Culicivora mexicana Bonap. Polioptila mexicana Sclater. But not of 

 Cassin, which is melanura. 

 Rare; summer resident; first individuals noticed April 25. " Winters in
