132. Mniotilta varia. Black and White Warbler. — Probably a 

 common migrant. We saw a few in the Maple Creek timber on May 29, 

 1905, which were undoubtedly migrating, as none were seen later. None 

 were collected. 



133. Helminthophila rubricapilla. Nashville Warbler. — ''In my 

 notes for June 8, 190G, I wrote: 'saw plainly a Nashville Warbler.' This 

 bird was within a few feet of me in the timber, and low down, so that I 

 saw it plainly and hardly think I could be mistaken in the species." 

 (Bishop.) Not recorded by Prof. Macoun. 



134. Helminthophila celata. Orange-crowned Warbler. — Reported 

 as a migrant by Prof. Macoun. "Common in families of flying young in 

 the Cypress Hills, July 25-30. No adult males found. The young were 

 aU in Juvenal plumage, or moulting into first winter." (Bishop.) 



Dr. Bishop called all his birds Helminthophila celata orestera (Ober- 

 holser), the Rocky Mountain Orange-crowned Warbler. 



135. Helminthophila peregrina. Tennessee Warbler. — On May 29, 

 1905, I saw a bird, within 10 feet of me in the Maple Creek timber, which 

 I was quite sure was a Tennessee Warbler, but none were collected. Tliis 

 species was reported by Prof. Macoun as a common migrant. 



136. Dendroica aestiva. Yellow Warbler. — Abundant in the tim- 

 ber; the commonest warbler. A nest was found building on May 30 

 1905, and a nest with young on June 30, 1906. 



137. Dendroica auduboni. Audubon's Warbler. — Mr. Eastgate 

 shot a female with food in its mouth, in a grove of pines in the Cypress 

 Hills on July 28, 1906. 



138. Dendroica maculosa. Magnolia Warbler. — The only one 

 seen was collected in the Maple Creek timber on June 8, 1906, an adult 

 male, probably migrating. 



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

 One was taken in the Maple Creek timber, on June 8, 1906, in the wave 

 of migrants. 



140. Geothlypis tolmiei. Macgillivray's Warbler.^ — I saw a few 

 in the Cypress Hills, on May 31, 1905, but none were collected. Prof. 

 Macoun reported it as breeding there. Dr. Bishop found it common there 

 in families from July 25 to 30, 1906. 



141. Geothlypis trichas arizela. Pacific Coast Yellow-throat. — 

 Uncommon in the underbrush along the creeks, in the Cypress Hills and 

 in the drier portions of the sloughs. Dr. Bishop referred all the birds 

 taken to this subspecies. Prof. Macoun recorded brachidactyla as a com- 

 mon summer resident. 



142. Setophaga ruticilla. American Redstart. — A few were seen 

 in the Maple Creek timber on May 29, 1905. Probably a common migrant. 

 One was taken on Maple Creek on June 8, 1906. 



143. Anthus spragueii. Sprague's Pipit. — Entirely overlooked in 

 1905, probably because we did not know where and how to look for it or 

 realize the difficulty of seeing it or hearing it. It was really fairly common 

 on the prairies in 1906, frequently heard and less frequently seen.
