when some entered the open door of the netted-in veranda and became 

 prisoners. 



Warbling Vireos were visitors to my water-troughs in Dawson County. 

 I have noticed them eating wild rose leaves. 



166. Helminthophila celata. Orange-crowned Warbler. — Captain 

 Thorne gives this warbler as "common in April and May." I have seldom 

 seen it. About half a dozen of these birds were observed by me associating 

 with Yellow Warblers at Mr. J. H. Price's ranch (Knowlton) on May 27, 

 1907. 



167. Dendroica aestiva. Yellow Warbler. — Abundant summer visi- 

 tor to both counties, arriving about the middle of May. Scarce in the 

 pines. Nested all over my ranch near Terry in trees or bushes indiffer- 

 ently. Of four nests examined in the brush at our north window on June 

 22, 1893, two contained young birds. Their mothers showed many signs 

 of distress, and performed antics in the bushes near to attract my atten- 

 tion. These nests were beautiful soft cups, of dried grass with wool and 

 hair interwoven, placed in the forks of saplings. One nest enclosed a 

 young choke cherry, and another small dead tree as well. 



168. Dendroica coronata. Myrtle Warbler. — Tolerably common 

 on the spring migration but usually met with in small niunbers. A flock 

 was seen on Whitney Creek (Custer County), associating with Yellow 

 Warblers, on May 7, 1893. Another flock appeared at my ranch near 

 Terry on May 2, 1894. I have noticed tliis warbler in the pine-hills and 

 river valleys alike. 



169. Dendroica striata. Black-poll Warbler. — Captain Thorne 

 gives this bird as ''Common in ]\Iay." I have not observed it. 



170. Dendroica townsendi. Townsend's Warbler. — Rare. I saw 

 the bird for the first time on May 18, 1894, when an adult male came to the 

 north window of my ranch in Custer County. Like the Redstart it was 

 strongly attracted by the flies inside the glass, and remained for a consid- 

 erable time in the bushes and creepers which grew almost against it. I was 

 thus enabled to watch the lovely warbler from within the room. On May 

 11, 1896, the same bird (or another) was again observed under exactly 

 similar circumstances. 



171. Seiurus aurocapillus. Oven-bird. — Rare. Captain Thorne took 

 a male on July 23, 1888. I have not seen it. 



172. Seiurus noveboracensis notabilis. Grinnell's Water-Thrush. — 

 Rare. Captain Thorne mentioned: "One juvenile taken Sept. 12, 1889." 

 On May 24, 1905, I observed a single bird in cottonwoods along the Yellow- 

 stone at Mr. W. S. Haley's ranch in Custer County. 



173. Geothlypis trichas occidentalis. Western Yellow-throat. — ■ 

 Dr. J. A. Allen found this species "More or less common along all the 

 wooded streams, from the Missouri to the Musselshell, and quite abundant 

 at favorable localities." Captain Thorne has a record of four examples 

 in spring. I have not come across it. 



174. Icteria virens longicauda. Long-tailed Chat. — Common sum-
