NORTH AMERICAN BIRDS. 433 



eggs of this species, showing their extreme variations. Three of these are pure 

 white, unmarked; the fourth is very obscurely marked with reddish specks at the 

 larger end, while the fifth is distinctly speckled over the entire surface with vlnace- 

 ous cinnamon, but chiefly at the larger end; the sixth is marked generally over the 

 entire shell. These variations may exist in the eggs of a single set, but usually the 

 specimens in sets are of one type or the other plain white or speckled. The sizes 

 of the six eggs just described are .68x.49, .69x.53, .71x.51, .72x.54, .73x.53, .74x.53. 



733a. QBAY TITMOUSE. Parus inornatit* i/rineus Ridgw. Geog. Dist. New 

 Mexico and Colorado to Arizona, Nevada and California east of the Sierra Nevada. 



I have no information regarding the nidification of this variety of Pan/.v ///- 

 ornatns. Their nesting habits, however, can differ but little if any. 



733b. ASHY TITMOUSE. Parus inornatus cineraceus Ridgw. Geog. Dist. 



Lower California. 



There appears to be nothing published regarding the nidiflcation of this Tit- 

 mouse of Lower California. 



734. BRIDLED TITMOUSE. Parus wollweberi (Bonap.) Geog. Dist. West- 

 ern 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 Final and Santa Catalina Mountains of Arizona. 

 It is gregarious, except during the breeding season, going about in small companies. 

 It was frequently found, especially in the fall and winter months, associated with 

 flocks of the Plumbeous Bush-tit (Psaltriparus plumbcus) and a pair or more of Ari- 

 zona Woodpeckers (Dryobates Arizona?) are generally found in the band. He observes 

 that the Bridlea Titmouse is as unsuspicious and as fond of the society of man as the 

 Black-capped Titmouse (Parus atricapillus). On two occasions he discovered it 

 breeding, the nests being located in natural cavities of live oaks, close to. his house. 

 The first was found May 9, 1884, which was in a cavity rormed 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 hollow was lined with 

 cottonwood down, the fronds of some small rock-ferns, and bits of cotton-waste that 

 had been used to clean the machinery 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 .63x.48. Another 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 fur. This nect contained four young just hatched and two eggs, similar to 

 the last in color plain, dead white, and measure .65x.51, .67x.53. The eggs are said 

 to range from five to s*ven in number. 



735. CHICKADEE. Parus atricapillus Linn. Geog. Dist. Eastern North 

 America, chiefly north of 40, west to the Plates. 



The little Black-capped Chickadee or Titmouse is an abundant species in East- 

 ern United States, north of the Potomac and Ohio Valleys. The usual nesting time 

 is about the middle of April. The late Colonel Goss gives it as a common resident
