 The White-throated Sparrow is an abundant spring and fall 

 migrant in all parts of the state. They have been noted from 

 March 17 to May 23 and from September 18 to October 30. I 

 shot one 'female at Iowa City on May 20, 1894, a week after the 

 bulk had gone north. In April and October they are most abund- 

 ant, often the most common bird, in large scattered flocks, fre- 

 quenting low bushes, shrubbery and hedge-rows, spending much 

 time on the ground among dead leaves. In late spring the famil- 

 iar song note oi pea-peabody , peabody , pcabody , is often heard, giv- 

 ing rise to the common name of " Peabody-bird." The only 

 report of its occurrence in summer came from G. H. Berry of 

 Cedar Rapids, who .says: "All through June and July, 1905, I 

 could hear one or two of these sparrows in a swamp near here, 

 and think either they bred here or else they were bachelors that 

 remained here." 



Genus Spizella Bonaparte.

The Tree Sparrow is an abundant winter visitant in all parts of 

 Iowa. The species is abundant from October to April in the cen- 

 tral and southern parts of the state, and while flocks remain 

 throughout the winter in all portions of the state, in northern 

 Iowa they are less common in mid-winter than during the mi- 

 grating seasons. They remain in scattered flocks, feeding .almost 

 entirely upon the seeds of various weeds, and seem to find enough 

 of these projecting above the snow to support them even in the 

 .severest weather. Towards spring they become quite musical 

 and sing a sweetly modulated but rather feeble song. 



The Tree Sparrow resembles the Chipping Sparrow in general 

 appearance, but is somewhat larger, with a conspicuous dusky 

 spot on the otherwise unmarked breast.
