54 PACIFIC COAST AVIFAUNA • [No. i. 



Ampclis garridus Linn. 

 Bohemian Waxwing. 



On August 20, the day we arrived at the site of our winter camp on the 

 Kowak, I saw a flock of nearly fifty waxwings. They left a bunch of spruces near 

 the bank and circling out over the river flew back and disappeared beyond the 

 woods. Their manner of flight and general appearance closely resembled those 

 of our Cedar Waxwing in California. I did not again meet with the Bohemian 

 Waxwing myself. But a prospector showed me parts of the plumage of this 

 species from birds which he had shot near the head of the Kowak in April. He 

 said that toward the last of that month, the birds appeared in small flocks among 

 the birches and cottonwoods. 



Laniiis borealis ijivicfus new subspecies. 

 Northwestern Shrike. 



Tvpj; — (5 (not fully adult, judging from the light brownish wash in places on 

 the upper surface); No. 3366, Coll. J. G.; Kowak River, Alaska, April 15, 1899; 

 Collected by J. Grinndl. 



Description — Lower surface, white; foreneck, crissum and lower abdomen, 

 immaculate, otherwise distinctly and narrowly barred with vermiculate blackish 

 markings, two such bars being discernible on each feather. Upper surface (ex- 

 cept irregularly where washed with clay color), French gray merging on rump

 of lores and next to lower eyelid. Wings and tail, blackish, edged with lighter; 

 all the tail feathers white for an inch or more at base; outer web of outer tail 

 feather completely white, and inner web white for terminal 1.50; second feather 

 1.05; third, .80; fourth, .35 and remaining two pairs only narrowly tipped with

L. borealis invidus differs from L. borealis borealis in larger size, paler colora- 

 tion dorsally and greater extent of white markings. These diff"erences are fairly 

 comparable to those between the southwestern L. ludoviciamis excubitorides and 

 L. ludoviciamis proper. As shown by specimens at hand the summer home of 

 invidus is in Alaska, thus restricting true borealis to the eastern portion of North 

 America. In the winter zVzz'zV/z^.y comes south as far as the northwestern United 

 States. A specimen is in the Leiand Stanford Junior University collection (No. 758) 

 taken at Quincy, California, Feb. 17, '92; and I have a skin from Lac Qui Parle 

 County, Minnesota, both of which are typical of invictus. 



■ During the fall the Northwestern Shrike was met with in the Kowak Valley 

 rather sparingly. Single individuals would be seen, one or two in a day's tramp,, 

 in the willow bottoms where they w'ere the terror of the redpolls. On only one 

 occasion did I see more than one in a place. Near the head of Hunt River 

 where the canon winds into the foothills of the Jade Mountains, a party of us had 

 just pitched our tents on the evening of September i6th, when three shrikes made
