ARIZONA GOLDEN-CROWNED KINGLET 399 



may consist of anywhere from five to eleven, but eight and nine are 

 the commonest numbers; sets of four are probably incomplete, and 

 any numbers larger than nine are uncommon or very rare. The 

 eggs have very frail shells. They are indistinguishable from those 

 of the eastern race. The measurements of 40 eggs average 13.5 by 

 10.5 millimeters; the eggs showing the four extremes measure 14.8 

 by 11.0, 14.5 by 11.4, and 12.5 by 10.0 millimeters. 



Food. — Professor Beal (1907) has this to say about the food of the 

 western golden-crowned kinglet in California: "Only 9 stomachs have 

 been examined, but these in the nature of their contents are so similar 

 to those of the ruby-crown that statements applicable to the latter 

 are almost certain to apply as well to this species. No vegetable 

 matter was found in any of the 9 stomachs, and the insects belong 

 to the same orders and were taken in essentially the same proportions 

 as by the other species." 



The behavior, voice, and other habits of the western bird seem to be 

 similar to those of the eastern golden-crowned kinglet. Mr. Rathbun 

 tells me that, in western Washington, after the breeding season has 

 passed, the adults with their broods wander over almost the entire 

 region. During the autumn months there is a movement from the 

 higher altitudes to the lower, and the birds become very common 

 throughout the lowlands, always found associated with individuals 

 of their own species, and occasionally with some of the small arboreal 

 species that likewise are winter residents. 



REGULUS SATRAPA APACHE Jenks 



ARIZONA GOLDEN-CROWNED KINGLET 



HABITS 



Randolph Jenks (1936) has given the above name to the kinglets 

 that breed in the White Mountains and adjacent ranges in east- 

 central Arizona. After considerable discussion of its distribution and 

 habitat, and a detailed description of it, he sums up its characters as 

 follows: 



"It differs from R. r. olivaceus, its closest geographical counterpart, 

 by being a grayer bird, having a noticeable, wide gray, dorsal nuchal 

 band, having decidedly longer wings, tail, and bill, and having a 

 deeper and more richly colored central pileum. It differs from R. r. 

 satrapa in having a wide gray dorsal nuchal band, a much longer, 

 more slender bill, and a much more deeply colored central pileum. 

 Finally, it differs from R. r. clarus by being a considerably grayer 

 bird, having a wide gray dorsal nuchal band, and having longer wings, 

 tail, and bill." 



Probably it does not differ materially in its haunts and habits from 

 other adjacent races of the species.
