CATALOGUE OF CANADIAN BIRDS. 395 



A careful reading of Mr. E. T. Seton's article on the horned 

 lark in his "Birds of Manitoba " shows that the winter 

 birds seen in flocks are undoubtedly- this form. It is very 

 probable that praticola is a later arrival. Nash says " that 

 at Portage la Prairie praticola is a spring and fall visitant; 

 stays nearly all winter; disappears and reappears at intervals; 

 arrives about March 20th, reappears in August, and departs in 

 October." Now to me this is exactly what a bird breeding on the 

 "barren grounds" would do, so I conclude that this form is the one 

 mentioned by Nash and included in praticola by E. T. Seton. Two 

 darker coloured specimens taken at Indian Head, Sask., in Septem- 

 ber, 1 89 1, and named lioyti by Bishop are placed here. This is very 

 likely the form that Dr. Bell found breeding at York Factory and 

 Fort Churchill on Hudson bay. (Macoun.) 



Many of the above references go to hoyti or enthymia. 



Breeding Notes. — On May 29, 1893, at Rush lake, Sask., 

 I found three nests containing eggs of this species. The nests 

 were built in hollows in the ground, the brim of the nest flush with 

 the surrounding soil. Each nest contained four eggs similar to 

 those of the prairie homed lark. I secured two birds which are 

 easily distinguished from the prairie horned lark by their paler 

 form. (yV. Raine.) Nine nests of this lark were received at Fort 

 Anderson, a few of them from the Esquimaux and the others were 

 collected by us in the "barrens" and on the coast of Franklin bay. 

 The nest was usually composed of fine hay neatly disposed and 

 lined with deer hair. Several of the parent birds were secured by 

 snares placed thereon. (Macfarlane.) 



474. Oberholser Horned Lark. 



Otocoris alpestris enthymia Oberholser. 



In summer, Saskatchewan, with possibly southwestern Manitoba. 

 Breeding birds have been examined from Indian Head and St. 

 'Louis, Saskatchewan. {Oberholser.) Very common on the prairies, 

 particularly on the barren hills north of Maple creek and on the alka- 

 line plains. No nests were found but fully fledged young, in juvenal
