what puzzled to know' just what disposal to make of this bird. It agrees 
with australis in having the “red of the abdomen extended to the breast,” 
and the “ throat soft, umber brown,” but it has grayish lores, and a grayish 
bordering posteriorly to a black pileum. It is excluded from true tephro- 
cotis by having gray below the lores. 
I found the Gray-crown rather common above timber-line in June ; in 
August they were in swarms on the summit. The youngwere just out of 
the nest, Aug. 17, and kept up an incessant clamor, like young Chimney 
Swifts. The wind was very high at the time, and often while standing in 
a lode drift, the noise would go rushing by sounding like the distant jingle 
of sleigh bells. The only note I heard from the old birds was a thick- 
toned chirp ; in June they have a canary-like peyt-e-weet. The young birds 
are nearly unicolor, much like the color of the adult’s neck, but darker. 
They breed on ledges in the face of inaccessible cliffs. When they come 
down in winter they are very tame and confiding. 
31. iEgiothus linaria, Cab. Red-poll Linnet. — These cheery little 
fellows know nothing of thermometers, and are as jolly with the mercury 
— 300 as if it were June. 
32. Astragalinus tristis, Cab. Yellowbird. — Obtained a single 
bird, a male in full breeding plumage, in July, 1879. 
33 Astragalinus psaltria, Coues. Arkansas Goldfinch. — I found 
several in the willow bushes along the Rio Animas in October. Doubtless 
breeds. 
34. Chrysomitris pinus, By. Pine Finch. — Common ; breeds. One 
of the cheeriest of our few winter residents. 
35. Pocecetes gramineus, Bd. Grass Finch. — Common in the grassy 
valley near the headwaters of the Rio Dolores, and seen in flocks in 
Baker’s Park. Breeds. 
36. Melospiza lincolni, Bd. Lincoln’s Finch. — Very common ; 
breeds. Frequenting marshy places, they skulk through the underbrush 
like a sprite ; more like a mouse in action than a bird. In June they have 
a pretty wildsome song, the latter part of which reminds me of a Che- 
wink’s (. Pipilo erythroptkalmus) . At any time of the day, in June and 
July, you can hear the little performers pouring out their songs from their 
perches on the topmost branches of the dwarfed willows. 
37. Junco hyemalis aikeni. Ridg . White-winged Snowbird. — 
Rare ; not noticed until after two or three severe snow-storms in October. 
They are easily recognized by being heavier-built than their allies, as well 
as by the white wing-bands, though the latter are variable. 
38. Junco oregonus, Scl. Oregon Snowbird. — Common. First 
appearing at timber-line in September, stragglers come down and mix 
with flocks of caniceps , but by October they have taken full possession. 
When the severe winter weather begins they pass lower down. 
39. Junco oregonus annectens, Bd. Baird’s Snowbird. — Occa- 
sionally seen in flocks of the foregoing. 
40. Junco cinereus caniceps, Coues. Red-backed Snowbird. — 
Very abundant. The only Snowbird which breeds here, raising two,
