140 THE WILSON BULLETIN— September, 1921 



There are many nesting records of the Traill Flycatcher in east- 

 ern Nebraska, practically all of them in June. 

 Western Traill Flycatcher Enipidonax irailli hr(nrstrri Oberholser. 



This is the prevailing form of E. traillii in the Pine Ridge of 

 northwestern Nebraska where it is a common summer resident, 

 and it also occurs as a migrant and occasional breeder over west- 

 ern Nebraska, probably from about the 100th meridian westward. 



A University collecting party, working in Sioux County from 

 May 18 to June 1. 1900, noted this bird repeatedly during that 

 period (Cm ic ford. Proc. N. 0. U.. ii, p. 77), and a specimen col- 

 lected in Monroe Canyon on May 28 has been pronounced brcicsteri 

 by Dr. H. C. Obeiholser. During the summer of 1901 the "Alder 

 Flycatcher " was observed all through the summer by Cary and 

 Cariiker, who, though they found no nests, regarded it as prob- 

 ably breeding (Cary, Proc. N. 0. U.. iii, p. 73). L. M. Gates col- 

 lected a specimen of brcwsteri (Det. Oberholser) on May 21, 1914, 

 at Haigler. Nebraska, in the extreme southeastern part of the 

 state. Zimmer found the Traill Flycatcher in the brush along 

 the Loup River at Halsey from May 15 to August 31, in 1911 and 

 1912 (Proc. X. 0. v.. v, p. 81), and collected three specimens on 

 August 21 and 31. 1911. Unfortunately, these specimens are juve- 

 niles, but they have the more brownish color of hreicstcrl. 



Least Flycatcher Eiiipidonax minimus (W. M. & S. F. Baird). 



East of about the 98th meridian this, our smallest flycatcher, is 

 a more or less common migrant, and in the northeastern part of 

 the state, along the Missouri River, it is an uncommon summer 

 resident and breeder. Possibly it may occur as a rare migrant 

 farther west, but has not so been recorded as yet. 



It arrives in early May. At Falls City in 1904 Swenk collected 

 a male on May 2. At Lincoln in 1903 he collected a pair on May 

 9, a date considerably earlier than the other Lincoln dates, which 

 are May 13 to 21. In the fall it is very uncommon at Lincoln, the 

 only date being September 20, 1920 (C. E. Mickel). Apparently it 

 usually migrates a little later than does E. trailli from which it 

 is best distinguished in the field by its sharp, snappy "chc-bcc" 

 note, very different from the shrill, jerky " icec-zee-up " of the 

 Traill Flycatcher. Cary found it a rather common spring migrant 

 at Neligh May 10 to 20. but did not note it in the fall (Proc. N. 

 0. U., i, p. 25). L. Bruner has found it migrating at West Point. 



In 1877 Aughey first recorded this species from Nebraska, stat- 

 ing that it was rather common and occasionally bred in the north- 

 eastern portion of the state, and recording the taking of specimens 

 at Dakota City in May, June and July of 1865 and 1866. Dr. T. C. 

 Stephens informs us that it nests in that locality at the present 

 time. It also occasionally summers and breeds as far south along
