BIRDS OF COLORADO. 83 



iial, "Northern and Eastern North America and sporadically 

 Western North America (Colorado, California, etc.)." The 

 birds there referred to by Mr. Ridgway as being found in the west 

 are now considered by him as belonging to homorus. As the 

 authority for Maj. Bendire's remarks cannot be now learned 

 they are entered here to call attention to the record. 



394b. Dryobates pubescens homorus. Batchelder's 



Woodpecker. 



Resident; common. Hardly as common in Colorado as 

 its eastern representative is in the Mississippi Valley and much 

 less common than Cabanis's Woodpecker. To this form are 

 now referred all Colorado birds. It ranges in winter from the 

 plains to 10,000 feet and breeds from the plains to 11,500, but 

 is more common at the higher altitude in summer and at the 

 lower in fall and winter. 



396. Dryobates scalaris bairdi. Texan Woodpecker. 



Resident; rare and local. It is rather strange that this 

 bird should have been overlooked by previous collectors, as W. 

 P. Lowe writes that it occurs regularly in Pueblo and Huerfano 

 Counties. More commonly seen in spring and fall and oc- 

 casionally an old bird in winter. Mr. Lowe has taken several 

 of the birds and the skins have been positively identified, so 

 there can be no doubt of its occurrence as he states. This is 

 the first and only Colorado record for the bird and carries its 

 known range over three hundred miles to the eastward. 



401b. Picoides americanus dorsalis. Alpine Three-toed 



Woodpecker. 



Resident; not common. Throughout the mountains from 

 about 8,000 to 12,000 feet. Occasionally a few feet lower, but 

 remains even in winter in the pine belt chiefly at about 10,000 

 feet. It is not common anywhere but is scattered quite gen- 

 erally through the mountains. D. D. Stone found a nest with 

 five young birds near Hancock, July 10, 1883, at about 10,000 

 feet. (O. & O. IX. 1894, 9 and 10.) 



402. Spyrapicus varius. Yellow-bellied Sapsucker. 



Migratory; rare. The eastern variety scarcely coming west 

 to the Rocky Mountains. It was taken by C. E. Aiken, pre- 

 sumably in El Paso County, and there is a single specimen in 

 the Maxwell Collection. 



402a. Sphyrapicus varius nuchalis. Red-naped Sap- 

 sucker. 

 Summer resident; common. Breeds from the plains to 



12,000 feet, but the great bulk of nests are made between 8,000 



and 9,000 feet. Arrives in April but eggs are not found until 



the first half of June.
