542b. Passerculus sandwichensis alaudinus (Bonaparte)—-WESTERN Sa- 
VANNA SPARROW. 
Entire state, occurring only as a migrant in eastern Nebraska; may 
rarely breed westwardly, though not knowntodoso. Cherry county, 
Neligh, Lincoln,Omaha—migrating; much the same dates as savanna. 
In a series of sixteen specimens from Lincoln taken during migra- 
tions only three can be referred to alaudinus, and only one of 
these is typical. 
545. Coturniculus bairdii (Audubon)—Bairp Sparrow. 
An uncommon migrant, dates much as the Savanna Sparrow, com- 
monest in fall! Breeds north of Nebraska. Lincoln, West Point, 
O’ Neill—migrating. 
546. Coturniculus savannarum passerinus (Wilson)—GRASSHOPPER SPAR- 
ROW. 
An occasional specimen is taken along the eastern edge of the state 
apparently nearer this than the following form, though even 
there bimaculatus predominates. Omaha, Peru, Lincoln. Breeding 
questionable. 
546a. *Coturniculus savannarum bimaculatus (Swainson) WESTERN GRASS- 
HOPPER SPARROW. f 
An abundant migrant and very common summer resident over al- 
most entire state, arriving first week in May, breeding from late May, 
through June, departing in early October. Sioux, Cherry and Holt 
counties, Neligh, West Point, Lincoln, Beatrice—breeding. 
[547. Ammodramus henslowii (Audubon)—-HENSLOoW SPARROW. 
Has been recorded from Nebraska, and is known to occur west to 
Minnesota. The only specimen available has been indentified by 
Oberholser as the Western. It is likely that all, or most, of the records 
refer to that form, but until more material is examined it cannot be 
safely assumed that they do. Its occurrence is probably analogous 
to that of the Grasshopper Sparrow.] 
547a. *Ammodramus henslowii occidentalis Brewster—WESTERN HENSLOW 
SPARROW. 
A rare migrant. Aughey ‘‘only occasionally met with this bird,” 
and the only specimen he examined was taken at Kearney Junction 
in September, 1874. A specimen was taken at Lincoln, April 22, 1899, 
by Wolcott, and Bruner has seen it at West Point. It may occa- 
sionally breed locally in the state, since Trostler took a set of eggs, 
with female bird, at Omaha, bélonging to this species and probably 
to this form. 
548. Ammodramus leconteii (Audubon) —L&EcoNTE SPARROW. 
A very common migrant, arriving in late March and early April 
and lingering late into May, reappearing in late September and 
remaining commonly until November, occasionally even to the mid-
