fact that its nest, eggs, and breeding habits were unknown. E. 

 A. Preble first found the adults of both sexes and >oung just 

 from the nest, July 23 to 30, 1900, at Fort Churchill, on the west 

 shore of Hudson Bay, frequenting dwarf spruces in small valleys 

 and ravines (N. A. Fauna, 22, Biol. Surv., 1902, p. 120). 



249- (554)- Zonothchia leiicoplirys (Forst.). White -crowned 

 Sparrow. 

 This large, handsome Sparrow is a rather uncommon migrant 

 in most parts of Iowa, although generally distributed, but be- 

 comes fairly common at times. The}- have been noted in Iowa 

 from April 5 to May 23 and from September 26 to October 26. 

 They usually appear a little later than Z. albicollis, but the two 

 species are frequently seen together, frequenting the same situa- 

 tions — the borders of woods, thickets and hedge-rows, where it 

 sometimes utters a rather pleasing song in the springtime. The 

 White-crowned Sparrow breeds, principally, north of the United 

 States and has not been observed in Iowa in summer. 



250. (554a). Zoiiotrichia leucophrys gambeli {^nXX.). Intermedi- 

 ate Sparrow. 



The Intermediate or Gambel Sparrow resembles the preceding 

 very much, but is distinguished by having the lores gray or ashy, 

 continuous with white stripe over eye, the black of forehead not 

 descending to eye. The species has been rarely taken in Iowa 

 during migrations. Ridgway gives its range as "straggling east- 

 ward across the Great Plains to E. Texas, Kansas, Iowa and Min- 

 nesota (Minneapolis)" (Bds. N. and Mid. Am., i, 340). 



T. M. Trippe first records it from Iowa: ' ' Zoyiotrichia Gambellii. 

 A specimen shot in spring, in Decatur county, agrees precisely 

 with Baird's description" (Proc. Bost. Soc, xv, 1872, p. 273). 

 John Krider states: "In the month of May, 1875, I shot two 

 specimens in Iowa, the first of this bird I ever met with" (Forty 

 Years' Notes, p. 47). W. W. Cooke (Bird Migr. in Miss. Val., 

 1884-85, p. 196) says: "A single specimen was reported from 

 Iowa years ago . . . It is the more liable to be overlooked, as it 

 arrives after the other (Z. leucophrys) and without clo.se examina- 

 tion is naturally mistaken for it." 



Dr. I. S. Trostler writes that the species is a common migrant 

 in Mills and Pottawattamie counties. Two specimens in my col-
