 stripe; feathers of back, and especially scapulars, umber brown with conspicuous 

 white,' or pale buffy, edgings ; breast, sides, and flanks deep buff or ochraceous, 

 the breast marked, if at all, with a few narrow dusky streaks, the sides more 

 heavily and broadly marked in chains ; the buffy sides of the head include slaty

 extremity; throat and belly clear white. "Length 5.50 (1397) ; wing 2.25 (57.2) ;

IF in moments of insight we are sometimes tempted to bless our obscurity, 

 we have good example for it in this shy little Sparrow. The probabilities are 

 that the bird trespasses upon our borders yearly, yet, so far, only one sharp eye 

 has caught him poaching. Certain it is that he is abundant in the interior, 

 and certain it is that he is not uncommon on the Atlantic coast in winter. Ergo 

 he must pass over Ohio, at least occasionally ; and what more natural than 

 that he should pause for breakfast somewhere in the hospitable swamps which 

 line the southern shores of Lake Erie? It gives ornithologists a properly 

 chastened sense to realize that here is one bird at least which is still too clever 

 for him. But on second thought we pocket our chagrin good naturedly; for 

 here is one bird, too, whose humble, stealthy ways deliver him from the seat 

 of scorn upon mi-lady's bonnet and whose eggs are not found in every small 

 boy's sawdust box. 



The Nelson Sparrow was first described from the Calumet marshes near 

 Chicago in 1877. Since then it has been found numerously in the prairie 

 marshes of the West, but as yet comparatively little is known of its life history. 

 Col. Goss (Birds of Kansas, 1891, 449) speaks of the song as "a short, weak, 

 unmusical twittering warble." Certain parties 1 are said to have found it
