62 Brooks, Notes on Birds of Okanogan, B. C. [f&n 



Aeronautes melanoleucos. White-throated Swift. — This is another 

 species, new to Canada, that I have so far been unable to secure specimens 

 of. Three or four pairs bred in the summer of 1907 in the high cliffs at 

 the outlet of Vaseux Lake; they were daily seen by Mr. Green and two 

 other close observers and there can be no doubt as to their identity. 



Otocoris alpestris arcticola. Pallid Horned Lark. — Mr. Green this 

 year took the eggs of the Pallid Horned Lark on the high mountains above 

 timber line, between the Okanagan and Similkameen valleys and collected 

 the female, which is now in my collection. 



This is the breeding form on all the high mountains of the Province, 

 Otocoris a. merrilli being restricted to the arid lower levels; nowhere 

 do their breeding ranges impinge on each other. 



Nucifraga Columbiana. Clarke's Nutcracker. — Clarke's Nutcracker 

 is a fairly common though irregular breeder at low elevations throughout 

 the Okanagan district. I took two nests March 23 and 30, 1906, both in 

 ponderosa pine trees, and Mr. Green has taken three more this year at 

 Osoyoos. Two broods are reared, as I have seen nestlings being fed in 

 June. 



Dolichonyx oryzivorus. Bobolink. — A regular summer visitant and 

 increasing. Breeds as far north as Lumby; common at Penticton. 



Coturniculus savannarum bimaculatus. Western Grasshopper Spar- 

 row. — Scarce breeder from Vernon south. 



Chondestes grammacus strigatus. Western Lark Sparrow. — Com- 

 mon breeder at Osoyoos, scarce at Vernon. 



Zonotrichia leucophrys gambeli. Intermediate Sparrow. — The In- 

 termediate White-crowned Sparrow breeds from 1200 feet (Okanagan 

 Landing) up to timber line (Osoyoos district). 



Spizella breweri. Brewer's Sparrow. — Tins year Mr. Green found 

 Brewer's Sparrow a fairly common resident in sage brush areas at Osoyoos. 

 Previous to this the only records I am aware of were Mr. Rhoads's at Ash- 

 croft, and one taken by myself on migration at Vernon. My record for 

 158-mile House, Cariboo district, proved a mistake of identity, the two 

 males taken being Spizella pallida — also new to the British Columbian 

 list. 



Junco hyemalis montanus? — The Juncos of the Okanagan district are 

 very puzzling. Dr. Dwight tells me that two I have sent him are very 

 close to montanus, others are typical shufeldti, while during migrations a 

 bewildering range of variation can be seen. 



Roughly speaking, the wintering birds and those that breed at high 

 altitudes are typical shufeldti, those breeding in the Pine belt approach 

 montanus, while the migrating hordes show a very large admixture of 

 hyemalis, typical examples of which I have taken as far west as the west 

 slope of the Cascades at Chilliwack. 



Lanius ludovicianus gambeli. California Shrike. — Mr. Green sent me 

 a very dark example of the California Shrike taken at Osoyoos in March 

 of the present year — the second record for British Columbia.
