"Prize" Photographs, 



A number of our subscribers have 

 br<mg-ht us to task for not includ- 

 ing- our "cover" picture within the 

 text, that it might not be lost in binding 

 the volume. Therefore we will publish 

 our "cover" picture within the text por- 

 tion each month, and we think all will 

 ag-ree that the September and October 

 pictures are well worth the space they 

 occupy. Many of 

 o u'r correspond- 

 ents have compli- 

 mented us on our 

 "little Hawks," 

 which adorned the 

 September cover, 

 and this month 

 we are g-lad to be 

 able to g-ive an- 

 other photog-raph 

 of one of the little 

 Redtails sing-lj-. 



We are indebted 

 to Mr. E. E. Mas- 

 terman, of New 

 London, Ohio, for 

 these photog-raphs 

 and the privileg'e 

 of publishing- 

 them.

The Virco gilvtis^ found as a reg-ular

 west of the Cascade range of mountains,

 throughout all the southern regions of 

 British Columbia. In g-eneral appear- 

 ance, both of form and plumag-e, as well 



as in most of its habits, it does not differ 

 much from the more familiar Red-eyed 

 species of this g-enus, though the dis- 

 tinctive markings on the head of the 

 latter are wanting- in the Warbling- Vireo.
