ron. Neb. It is possible that this is a fairly common bird during 

 migrations in northwest Nebraska. 



8. Tyrannus vcrticalis Say — Arkansas Kingbird. 



Our latest date in the fall for this bird in Sioux county is 

 September 11. We were in the same general vicinity until Sep- 

 tember 20, but saw none of these birds after the above date. The 

 Arkansas Kingbird is an abundant breeder in this region and was 

 very common up until September 11. 



9. Tyrannus vociferus Swainson — Cassin Kingbird. 



On the supposition that the Cassin Kingbird should occur in 

 western Nebraska a careful watch was kept for it during the sea- 

 son. We were therefore very much pleased. On September 9, 

 while driving from Crawford to Harrison, to find a kingbird which 

 appeared to be this species, and upon securing the bird we found 

 our identification to be correct. The exact locality where this 

 specimen was taken is three miles west of Glen. On September 

 12 a second specimen was collected at the mouth of Monroe Can- 

 yon. While returning to Crawford on September 20, by automo- 

 bile, we observed a flock of eight or nine Cassin Kingbirds near 

 Fort Robinson and a third specimen was obtained. It is probable 

 that this species is a common migrant in Sioux county, at least 

 in the fall. 



10. Nuttallornis horealis (Swainson) — Olive-sided Flycatcher. 



On June 8 Mr. Mickel found a pair of these flycatchers in a 

 grove about two miles west of Kimball, Neb. The specimen taken 

 proved to be a female. 



11. Pica pica liudsonia (Sabine) — Magpie. 



Mr. Mickel saw four Magpies near Gresham, Neb., on October 

 10. We think this worthy of mention since this species seems to 

 be retreating westwardly and is now seldom observed in the east- 

 ern part of the state. 



12. Nucifraga cohimMana (Wilson) — Clarke Nutcracker. 



While this species has been known to occur along the Pine 

 Ridge in northwest Nebraska, only one specimen had been taken 

 previous to 1919, that taken by Mr. J. T. Zimmer on November 

 29, 1910. On September 16 we observed and secured a Clarke Nut- 

 cracker at the mouth of Sowbelly Canyon, Sioux county. This Is 

 almost two and one-half months earlier than Zimmer's specimen. 

 One was also observed in Monroe Canyon. Sioux county. Septem- 

 ber 18. 



13. Carpodaciis cassini Baird — Cassin Purple Finch. 



On the morning of September 18, Mr. Dawson discovered a 

 female of this species in Monroe Canyon, Sioux county, and we
