400 General Notes. [july 



Picoides americanus dorsalis. Alpine Three-toed Woodpecker. — 

 One was observed on the pine mesas near Boulder at an elevation of about 

 5800 feet on December 17, 1911, and on January 7, 1912 (probably the 

 same individual). 



Asyndesmus lewisi. Lewis's Woodpecker. — A few birds remain all 

 winter in the orchards and cottonwoods of the plains in Boulder Co. I 

 have a few records for December, February, and March. 



Zonotrichia leucophrys gambeli. Gambel's Sparrow. — During 

 the three past winters I have observed a small flock of Gambel's Sparrows 

 wintering near a sheltered outcrop of sandstone on the plains east of Boulder. 

 A specimen was taken for record on February 18, 1912. 



Melospiza melodia montana. Mountain Song Sparrow. — I have 

 found this sparrow at Tolland, 9000 feet, in the middle of July, though not 

 as numerous as the white-crowned and Lincoln's Sparrow which frequent 

 that Park in large numbers. 



Bombycilla cedrorum. Cedar Waxwing. — On September 9, 1910, 

 with Mr. H. C. Williams, I saw five or six in City Park, Denver. On 

 September 11, 1910, in Boulder Canon, near Boulder, I saw three Cedar 

 Waxwings feeding on the berries of Crataegus. These are the only records 

 of this species that I have. 



Dendroica townsendi. Townsend's Warbler. — In September, dur- 

 ing the fall migration, I have found this warbler to be not uncommon 

 in Boulder Co. I have noted it in varying numbers from August 28 to 

 September 28. 



Catherpes mexicanus conspersus. Canon Wren. — A nest with 

 young was found on July 23, 1911, in the same crevice that contained the 

 nest recorded in 'The Auk,' 1911. — Norman deW. Betts, Boulder, Colo. 



Correction. — We regret very much to state that two of the records 

 published in our ' Notes from Eastern Alberta,' Auk, Vol. 28, No. 4, 

 Oct., 1911, have since proved erroneous: Sleganopus tricolor proved refera- 

 ble to Lobipes lobatus, and Macrorhamphus griseus griseus to scolopaceus. 

 Prof. W. W. Cooke kindly determined these specimens. 



We moreover do not wish to be responsible for the three following 

 records, — Ammodramus savannarum bimaculatus, Anthus spraguei, and 

 Icterus spurius, as they are apparently new for Alberta (Prof. W. W. 

 Cooke in litteris). These records are obviously of no value as we did not 

 save the skins, but depended upon the more or less brief descriptions of a 

 handbook in identifying them. — Winthrop S. Brooks, and Stanley 

 Cobb, Milton, Mass. 



Birds and the Cotton Scale. — I notice in the January Auk, p. 113, an 

 account of birds eating the " Chinese Cotton Scale " in Colorado Springs. 

 Why ' Chinese ' I do not know; the insect in question is Pulvinaria in- 

 numerabiUs Rathvon, common in the United States. Sanders has recently 

 considered it identical with the European P. vitis, but it is probably distinct,
