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 known to do so. 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) — Baird 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. 

 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) — Henslow 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, belonging to this species and probably 

 to this form. 



548. Ammodramus leconteii (Audubon) — Leconte 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-
