young. They were constantly going back and forth bringing crickets, 

 and judging from the number disposed of in the three hours I noticed 

 them, the amount required in a day must be enormous. 



91. Picus villosus var. Harrisi (Audubon). Harris's 

 Woodpecker. 



Sparingly distributed through the forests of the Blue Mountains 

 during the summer months; in spring and fall they frequent the 

 shrubbery along the creeks in the valleys, and a few winter in such 

 localities. A set of three eggs taken May 29, 1876, in the Blue 

 Mountains, measure 1.01 X .71, .97 X .70, 1 X -71. They are of 

 a clear white color, oblong oval in shape, slightly pointed. The nest 

 was in a dead pine about twenty feet from the ground. 



92. Picus pubeseens var. gairdneri (Aud.). Gairdner's 

 Woodpecker. 



I only met with this species in the John Day River Valley, Ore- 

 gon, and it appears to be rare there. Two sets of eggs from Cali- 

 fornia measure as follows: First set, .72 X -59, .71 X -59, .70 X .58 

 and .70 X -60 of an inch. Second set, .75 X .51, .71 X -5.1, .70 X 

 .52, .70 X .51, .69 X .53. They are clear white. 



93. Picus albolarvatus (Bd.). White-headed Woodpecker. 



Not common, only met with in the pine forests of the Blue Moun- 

 tains. I found a nest of this species May 27, 1875, in a dead pine, 

 and about twenty-five feet from the ground, containing two fresh 

 eggs, measuring 1.02 X -75 and 1.02 X -73. The eggs from another 

 set average .90 X -76. They are clear white in color, but not glossy. 

 When passing from tree to tree this bird utters a clear ringing note, 

 like witt witt. It remains here throughout the winter; its mode of 

 flight is straighter and less undulating than that of most woodpeckers. 

 The white about the head is always soiled, becoming a light smoky 

 gray. 



94. Picoides arcticus (Gray). Black-backed Three-toed 

 Woodpecker. 



I have seen what I take to be this species on two occasions near 

 Soda Springs, on the Blue Mountains. 



95. Sphyropicus nuchalis (Bd.). Red-naped Woodpecker. 

 Moderately common, confined to the aspen groves in the Blue 



Mountains, where it breeds. It nests earlier than most woodpeckers 

 about here. The only nest I have examined contained good sized 

 young, June 12, 1875. Their nests are in aspens, and generally in- 

 accessible. I noticed three in the season of 1876 in such situations,
