734. Parus wollweberi (Bonap.) [39.] 



Bridled Titmouse. 



Hab. Western Texas, Southern New Mexico and Southern Arizona, south into Mexico. 



Mr. W. E. D. Scott found this Titmouse to be a rather common 

 resident in the evergreen oak region of both the Pinal and Santa Cat- 

 alina Mountains of Arizona. It is gregarious, except during the breeding 

 season, going about in small companies. It was frequently found, es- 

 pecially in the fall and winter months, associated with flocks of the 

 Plumbeous Bush-tit {Psaltriparus plumbeus) and a pair or more of Ari- 

 zona Woodpeckers {Dryobates ArizoncB) are generally found in the 

 band. He observes that the Bridled Titmouse is as unsuspicious and as 

 fond of the society of man as the Black-capped Titmouse (Parus atrica- 

 pilhis) . On two occasions he discovered it breeding, the nests being loca- 

 ted in natural cavities of live oaks, close to his house. The first was found 

 May 9, 1884, which was in a cavity formed by decay, in an oak stump; 

 the opening, which was a small knot hole where the branch had been 

 broken off^, was about three and a half feet from the ground. The hol- 

 low was lined with cottonwood down, the fronds of some small rock' 

 ferns, and bits of cotton-waste that had been used to clean the machin-i 

 ery of a mill near by. The nest contained three pure white, unspotted 

 eggs, with a pinkish tinge before being blown. Two of these were 

 accidentally broken ; the unbroken one measures .63 x .48. Anothe;t 

 nest was found May 9, 1885, in a similar location, some six feet from 

 the ground. In addition to the material of the nest already mentioned, 

 there were decayed grasses and rabbit's hair. This nest containejS^ 

 four young just born and two eggs, similar to the last in color — plain, 

 dead white, and measure .65 x .51, .67 x .53. The eggs are said to 

 range from five to seven in number. 



735. Parns atricaplUus Linn [41.] 



GUokadee. 



Hab. Eastern North America, chiefly north of 40**, west to the Plains. 



The little Black-capped Chickadee or Titmouse is an abundant 

 species in Eastern United States, north of the Potomac and Ohio 

 Valleys. The usual nesting time is about the middle of April. Col. 

 Goss gives it as a common resident of Kansas, begins laying early in 

 April. 



The nest is constructed in deserted Woodpecker holes, natural,;
