song which thev used to sing in Illinois. A nest I found in June was 

 placed in a spruce bush, about three feet from the ground, and contained 

 four fresh eggs. After getting the first brood off their bills, the White- 

 crowns become scarce in the Park but numerous among the stunted bushes 

 above timberline, where they raise a second brood ; thus making a double 

 migration in the breeding season, and keeping their love-song in fashion 

 until late in the fall. In September they again become plentiful in the 

 Park. and. haunting the roads, linger until October. 



46. Chondestes grammica. Bp. Lark Finch. — Common in the Park 

 all summer. Though I found no nests, I am confident it breeds here. 



47. Pipilo maculatus arcticus. Cones. Arctic Towhee. — Found in 

 April ; very shy ; probably breeds. 



4S. Pipilo chlorurus, Bd. Green-tailed Towhee. — Common from 

 April to November. A sweet songster in the breeding season, but always 

 very shy. Going up to a clump of bushes one day in May. a Green-tailed 

 Finch fluttered out from the opposite side with wings trailing, feigning 

 injury, at the same time uttering a sweet, complaining cry. The nest I 

 could not find, though I searched every foot of the thicket. 



49. Sturnella magna neglecta. Allot. Western Meadow Lark. — ■ 

 Rare. During the warm days of autumn, a few Larks straggle up from the 

 Animas Park, where they are quite common. I can see no cause for their 

 migrating the wrong way — 3000 feet up — unless it is a scarcity of food. 



50. Scolecophagus cyanocephalus. Cab. Blue-headed Grackle. 

 — In early summer I found Blackbirds rare, but in August and Septem- 

 ber they suddenly appeared in swarms. I have no idea where they breed, 

 as I could not find a nest. In fall the flocks seem to have no particular 

 place to go, nor even an individual mind. If two or three of a flock fly 

 up, clucking as they go, they will be joined by another and another until 

 the whole flock takes wing, making a racket like J^tiiscalus purpureus. In 

 October they disappear. 



51. Corvus corax, Linn. Raven. — Common in fall and early winter. 



52. Picicorvus columbianus, Bp. Clarke's Crow. — A not uncom- 

 mon resident. Keep high up until October, when thev come around camp 

 in search of food. They occasionally ( ? ) breed as low down as 6500 feet. 

 though I think but rarely, as I have found them most abundant between 

 12,000 and 13, ocx) feet in summer and fall. Its characteristic salute is a 

 long, grating •' squa-a-a-a." which sounds like the warning protest of a 

 setting hen. 



53. Gymnocitta cyaiiDcephala. Bp. Bue Crow; PinonJay. — Very 

 erratic; found only in flocks. The Pinon Jay ranges fully 6doo feet higher 

 than pinons grow in San Juan. How high up they breed is more than I 

 can say. I found it in large flocks, in cottonwood groves, at 7000 feet, in 

 May: and again, in flocks equally as large, from 10,000 to 13,000 feet, in 

 October. 



54. Pica rustica hudsonica. Ridg- Magpie. — A very rare resident. 

 Probably nests near 11,000 feet. 



55. Cyanocitta stelleri macrolopha. Alien. Long-crested J \v. — Very
