SPECIES NOT FOUND IN WASHINGTON. 967 



B. C. No. 9. 



ALPINE THREE-TOED WOODPECKER. 



A O. U. No. 401 b. Picoides americanus dorsalis Baird. 



Description.— Similar to P. a. fasiiutus (q. ;■. p. 430) but central cuntluence of wliite 

 bars still more pronounced or complete, — back thus unmterruptedly white throughout its- 

 length centrally; white spotting on wings reduced, not extending to coverts. 



General Range. — Rocky Mountain region from .Arizona and New .Mexico north to 

 southern British Columbia. 



Occurrence in British Columbia.— This is the resident form of the southern and 

 eastern portion of the Prmince but I have never encountered it as far west as Okanogan. 



B. C. No. 10. 



GRAY RUFFED GROUSE. 



A. O. U. No. 300b. Bonasa umbellus umbelloides (Dough). 



Description.— Similar to B. u. logata (<;. v. p. 583 J but upperparts more strongly and 

 mure imiformly gray. The hen is more rufescent than the cock and the latter does not 

 appear to exhibit the same tendency to dichromatic variation (i. e. with gray o;- brown 

 plumage) which characterize lx)th B. uinbcllKs and B. 11. togata. 



General Range.^Rocky Mountain region of the United States and British America 

 west to .-Maska, east to Manitoba, inosculating with B. u. togata along western border of 

 B. C. range. 



Occurrence in British Columbia. — Theoretically confined to the eastern half of the 

 Province. Very pale examples have been taken at Quesnelle and others nearly as pale and 

 gray at Okanagan, but these pale gray forms may crop up at any locality where the char- 

 acter of the country and the climate favours a palely-coloured race. 



B. C. No. II. 



WIELOW PTARMIGAN. 



A, O. U. No. 301. Lagopus lagopus (Linn.). 



Description. — Adults in 7i'iiHcr: Tail-feathers except central pair black, tipped with 

 white; remaining plumage entirely pure white. Adult male in summer: "Head and fore- 

 parts rich chestnut or orange-brown, more tawny-brown on back and rump; the richer brown 

 parts sparsely, the tawny-brown parts more closely, barred with black; most of the wings 

 and the underparts remaining white" (Cones). Adult female in sujnmer: Similar but only 

 the wings remaining white; coloration more tawny than in male and more heavily, uni- 

 formly, and closely barred with black. Length 15.00-17.00; wing 7.50-8.00; tail 5.50. 



Recognition Marks. — Small crow size; tail (except central pair of feathers) always 

 black: to be known from succeeding by larger size and by lack of transocular dusky stripe. 



Nesting. — A'est: on the ground. Bags: 6-12, warm bnfify as to ground, bnblly blotched 

 and marbled with dark burnt sienna, nearly black. ,\v. size. 1.75 x 1.24. 



General Range. — Of circumboreal distribution, Europe, Asia and North .'\merica ; in 

 the latter south casually to New England and Sitka, Alaska; breeding from about Lat. 55 

 north t" the limit of trees. 



Occurrence in British Columbia. — Common in .Atlin. A specimen in the Provincial 

 Museum from Beaver Pass (near Barkcrville) appears to be the most southerly record for 

 the Province.

A. O. U. No. 302. Lagopus rupestris (Crinel.).

 remaining plumage (except black tail) heavily and coarsely barred brownish black and 

 ochraceous. Length 13.co-14.75; wing 7.00-7.50; tail 4.50.

 distinctive.
