75. Red-headed Woodpecker. Melanerpes erijtJiroceplialus. A 

 common summer resident. 



76. Xortlierii Flicker. Cohtptes cnir(it}is Jutni.^;. A cnimnoa 

 summer and occasional winter resident. 



77. Whip-poor-will. Antrostomus vocifcrus. The only note 

 the writer has is from Mr. Ludcke, who states that Dr. Gould has 

 heard it calling in the vicinity of ACcCook lake. There seems no 

 reason why they should not be there in abundance, for the writer 

 has heard them calling on the Iowa side of the Big Sioux, and 

 has estimated the presence of fifteen or twenty birds. 



78. XighthawK. Chordeiles virginmmts. jMay 30, 1915 (Al- 

 len) ; June 2, 1918 (Stephens). 



79. Chimney Swift. Ckaetura pelagica. One individual, 

 which had probaljly strayed over from the city, was noted near 

 Big Sioux river on May 20, 1918 (Stephens). 



80. Ruby -throated Humming-bird. Archilochus cohihris. 

 Noted on August 26, 1916 (Allen), and on August 28, 1916 

 (Stephens).

 summer resident, though less numerous than the preceding 

 species.

 (Allen). In 1918 found in McCook lake woods, and probably 

 breeding (Allen and Stephens). 



84. Phoebe. Sayornis phoehe. A common summer resident 



85. Olive-sided Flycatcher. Nuttallornis horealis. This 

 species was found just in time to be included in this list, viz., on 

 June 2, 1918. The writer had previously doubted its occurrence 

 here. On this occasion the bird, which was at once recognized 

 as a strange flycatcher, was perched ui)on the topmost branch 

 of a dead tree located in the dense portion of the woods bor-
