blown, rather sparsely spotted with irregularly shaped dark umber 

 brown dots, chiefly at the larger end." With one egg broken, he 

 gives the measurements of the others as ".77 x .59, .78 x .58, and .75 x .57 

 inches." Another nest found on June 6 "contained three slightly 

 incubated eggs, which do not vary in color from those already de- 

 scribed, except that the spots are of a slightly redder brown, and they 

 are more concentrated at the larger end. The eggs are rather smaller 

 and even more rounded in general shape than the other set spoken of, 

 being but little more pointed at one end than at the other. They 

 measure .72 x 53, .70 x .55, and .G8 x .53 inches, respectively." 



Grinnell and Swarth (1913) describe the eggs as "pure white in 

 color, with numerous abruptly-defined minute dots and spots of not 

 more than one-half millimeter diameter, nearly all agglomerated 

 around the large ends. In color these markings are mostly very dark, 

 of clove brown and sepia tones; a few approach drab. The eggs 

 measure : no. 74 : 18.3 x 14.5, 18.7 x 14.0, 18.8 x 14.1 ; no. 75 : 17.8 x 14.7, 

 17.8 X 14.6, 18.2 X 14.7." 



Frank Stephens (1890) gives measurements as 0.73 by 0.57, 0.74 by 

 0.55, 0.74 by 0.55, and 0.77 by 0.53 inch, with color similar to those 

 described by Scott. 



The measurements of 31 other eggs average 18.0 by 13.5 millimeters ; 

 the eggs showing the four extremes measure 19.7 by 13.9, 18.6 by 14.6, 

 17.2 by 12.4, and 17.7 by 12.2 millimeters. 



Young. — Florence M. Bailey (1904) found a nest with three newly 

 hatched young at Montoya, N. Mex., on June 15. But W. E. D. 

 Scott (1885) in Arizona found fully fledged young shifting for them- 

 selves on June 4 and on the same day "found a pair of these birds 

 just starting to build : but this was the second brooding, as the female 

 of the pair, which I took before I discovered the nest, clearly showed." 

 Again, he took on May 26 "two young males that had just left the 

 nest and were under the care of the male parent bird." 



Coues (1878) says of the young: "A specimen just from the nest is 

 brownish-gray above, white below, without a trace of olivaceous or 

 yellowish on the body; the quills and tail-feathers have yellowish- 

 olive edgings, rather stronger than in the adult, and there is a slight 

 whitish bar across the ends of the greater coverts. The bird bears 

 a superficial resemblance to a small faded specimen of F. plumheiLS^ 

 but is quite different." 



Ridgway (1904) says : "Texture of plumage looser and much softer 

 than in adults; coloration similar, but the gray of upper parts slightly 

 more brownish, white of under parts purer, and pale edgings to 

 remiges and rectrices and tips of greater coverts tinged with pale 

 olive."
