to Dismal river, Thomas county. Aughey reports it also from Sid- 

 ney and the Wood river, the latter probably in Custer or Dawson 

 counties. Very likely breeds in the state. 



463. Empidonax flaviventris Baird — Yellow-bellied Flycatcher. 



Aughey states that this flycatcher is present sparingly in eastern 

 Nebraska and that he has known it to breed along the Missouri, but 

 he does not give his evidence, and the latter statement is probabty 

 a mistake. He shot one near Dakota City in July, 1870. It has 

 been noted once at both Lincoln and West Point as a migrant by 

 B'runer. It is, however, quite rare. 



465. *Empidonax virescens (Vieillot) — Acadian Flycatcher. 



Whole of state, breeding commonly along the Missouri, less com- 

 monly along the lower Platte and the Elkhorn. Omaha, West Point, 

 Sioux county. Arrives second week in May, breeds in June, departs 

 early in September. 



466. *Empidonax traillii (Audubon) — Traill Flycatcher. 



Entire state, common, arrives first week in May or a day or so pre- 

 viously, breeds in June, and departs early in September. Omaha, 

 Peru, Nebraska City, Lincoln, Neligh, Sioux county. 



467. *Empidonax minimus Baird — Least Flycatcher. 



Eastern Nebraska rather rare; breeding along the Missouri river. 

 Omaha, Dakota City — breeding. Migrant at Lincoln, West Point, 

 and Neligh. Dates same as preceding. 



EXTRALIMITAL: 448. T. vociferans Swainson, the Cassin King- 

 bird, is a common summer resident in Colorado down to the foothills 

 and is present, though uncommon, at Cheyenne, Wyo. It may straggle 

 to western Nebraska during migration. 454. M . cinerascens (Law- 

 rence), the Ash-throated Flycatcher, has been taken at Cheyenne, 

 Wyo. 464. E. difficilis Baird, the Western Flycatcher, represents the 

 Yellow-bellied in the western United States. It is common in sum- 

 mer in Colorado, occurs in eastern Wyoming, and may reach western 

 Nebraska during migrations. 466a. E. t. alnorum Brewster, the Alder 

 Flycatcher, is a scarcely distinct form occurring in eastern United 

 States west to Michigan, but specimens from Sioux county, in ex- 

 treme northwest Nebraska, have been identified at Washington as 

 alnorum. Owing to the extreme distance from the limits of its ac- 

 cepted range it is not included as a Nebraska bird. Two small 

 western Empidonaces, 468. E. hammondi (Xantus), the Hammond 

 Flycatcher, and 496. E. wrightii Baird, the Wright Flycatcher, 

 especially the latter species, are apt to straggle into western Nebraska 

 during migrations. Both occur in Colorado and Wyoming, wrightii 

 abundantly and even to Cheyenne.
