At Devils Lake I first noted this species June 9, 1921, and it was only 

 occasionally seen there later.

Flycatcher. 



RiDGWAY, 1907, p. 550; breeding at Stump Lake, North Dakota. Judd, 1917. p. 

 20; rare, breeding in Turtle Mountains. 



I do not know of any other records for this species. 



179. Bmpidonax trailli trailli (Audubon). Traill's Flycatcher. 



CouES, 1878, p. 611; found this species common at Pembina during the first 

 week in June, but not later than the 9th. Specimens were taken June 2 to 9, 1873. 

 Judd, 1917, p. 21; common migrant in the prairie region, breeds in Turtle Mountains; 

 earliest migrants, May 8. 



I first noted this species May 30, at Devils Lake and as^ain at Cando, 

 June 2, where it was quite common around Mr. Judd's grove. One was 

 secured at Snyder Lake, Towner County, June 4, 192 1. In 192 1 several 

 were seen at the Turtle Mountains, August 3 to 7. 



180. Bmpidonax trailli alnonim Brewster. Alder Flycatcher.

AUvEN, 1875, p. 62; common in the bottom lands of the Missouri at Fort Rice, 

 1873. A few were also seen on Heart River. CouES, 1878, p. 611; very almnchLnt

 common during the first part of September at Fort Berthold. Judd, 1917, p. 21 ; 

 tolerably common summer resident of Turtle Mountains and woods around Devils 

 Lake. First seen June 4; eggs were found June 29. 



I found this species common at Devils Lake after May 20, 192 1, and at 

 all the localities visited, even in small groves on the prairies. Like the other 

 flycatchers, it is very beneficial, as it destroys many injurious insects.

Many horned larks were seen all over the state and some in the eastern, 

 part were noted as this species.
