283. Sciunis novcboraccnsis notabilis Ridgway. Grinnell's Water-Thrush, 



JuDD. 1917, p. 26; common at Rock Lake between May 9 and June 20, also in 

 the Turtle Mountains during July, where a nest with three eggs was found July 15, 

 1916. Freeman, 1919, p. 15 ; occasional transient visitant, May 19. 



Mr. Reid reports that he saw large numbers of these birds on Burnt 

 Creek. Burleigh County, May 15, 191 7. The species was at Devils Lake 

 from Alay 10 to 17, 192 1. It was also rather common and bred at Lake 

 Upsilon, Turtle Mountains, July 30 to August 7, 1920, as a juvenile bird 

 was taken there on July 30, 1920. 



284. Oporornis agilis (Wilson). Connecticut Warbler. 

 Abbott, 1880, p. 984; one taken July 11, 1879, near Pembina. 



I find but one published record for North Dakota. Mr. Alfred Eastgate, 

 who lived for several years at Stump I^ake, is my authority for two speci- 

 mens taken there May 3, 1903. 



285. Oporornis Philadelphia (Wilson). Mourning Warbler. 



CouES, 1878, p .568; breeding abundantly at Pembina, where specimens were 

 taken June 2 to ^o, 1873. Judd, 1917, p. 2y; tolerably common migrant on the prai- 

 ries and one of the most common summer residents of the Turtle Mountains. A 

 brood of young just from the nest was seen in July. FrEEMan, 1919, p. 15; tran- 

 sient visitant. May 26. 



I saw this species first at Devils Lake on ]\Iay 23. 1921. in a small willow 

 thicket near the edge of Creel Bay, and on June 3 collected two in a small 

 poplar grove near Cando, Towner County. At Grafton I saw a mounted 

 specimen in the Williams Collection taken there May 24, 1915. 



286. Geothlypis tricJias trichas (Linnaeus). IMarjdand Yellow-throat. 



Ridgway, 1902, p. 665 ; records this species from Fort Rice and Pembina, North 

 Dakota. He also examined one specimen from North Dakota. 



287. GeotJilypus trichas occidcufalis Brewster. Western Yellow-throat. 



CouES, 1878, p. 567 ; observed at Pembina and Turtle Mountains and specimens 

 collected at Pembina. June .=?, and Turtle Mountains, July 28. 187.^. Ridgway, IQ02, 

 p. 669; from the Missouri River, North Dakota. Ji'dd. 1917, p. 27; common summer 

 resident of prairies and the Turtle ^Mountains; earliest date. May 3. 



I first noted this species May 20. 1921, at Devils Lake. Later it was 

 seen at all the localities worked, and is no doubt locally common throughout 

 the state. Mr. Henry Williams took a male at Grafton, May 24, 1921. 



288. Icicria virens longicauda Lawrence. Long-tailed Cliat. 



Allen, 187s, p. 45 ; at Fort Rice, Morton County, this species was ven.' abundant

 also seen on Heart River and the Little Missouri. CouES, 1878, p. 569; up the Alis- 

 souri to beyond the mouth of the Yellowstone. Thwaites, 1906, p. 31 ; near Fort 

 Union, July 8, 1833, Maximilian records the yellow-breasted chat singing among the 

 thickets, especially in the rose bushes. Schmidt. 1904; lists it as occurring in the 

 western part of North Dakota, but gives no data. 



I first found this species on June 16, 192 1, at the Peaceful Valley Ranch 

 in willow thickets along the I^ittle Missouri River, but later, June 23, I
