PICIDiE. 
41. Picus villosus (L.), var. harrisii , Aud.—Harris’s Woodpecker. 
Not common in the valleys, but occasionally seen in the trees about Carson in the 
fall. 
42. Colaptes mexicanus (Swains.).—Red-shafted Flicker. 
Quite common in the valleys in summer; more numerous in fall. 
STRIGIDzE. 
« 
43. Otus vulgaris (L). var. wilsonianus (Less.)—Long-eared Owl. 
The only arboreal species that is at all common in the valleys. This bird is very 
numerous and lives the year round in the little copses of willows and the denser thick¬ 
ets bordering the swampy lands. Their food consists almost exclusively of field-mice, 
of which they kill vast numbers, a fact which should earn them the protection of the 
farmers. 
44. Speotyto cuvicularia (Mol.), var. hypugcea (Bon.).—Burrowing Owl. 
An abundant resident in some of the high pasture lands about Carson, their location 
being only determined by the presence of suitable burrows made by the several species 
of ground-squirrels ( Spermophilus .) 
FALCONID2E. 
45. Falco communis Grnel., var. anatum, Bon.—Duck Hawk. 
In fall making its appearance in considerable numbers along the slougbs and on the 
borders of the lukes, where it is always ready to capture the water-fowl disabled by 
the gunners. Its powers of wing are ample to enable it to overtake, in fair pursuit, any 
of the ducks, and many fall its victims. 
46. Falco sparverius L —Sparrow Hawk. 
Numerous. 
47. Pandion halicetus (L.).—var. carolinensis, Gruel.—Fish II iwk. 
Common on the lakes and streams. 
48. Circus cyaneus (L.). var. hudsonius, L.—Marsli Hawk. 
The most abundant of all the predatory birds. Exceeding numerous in the marshes. 
Never, I think, interfering with the water-fowl, except when wounded, and deriving 
its subsistence chiefly from the smaller species of rodents. 
49. Buteo borealis (Gmel.)., var. calurus, Cass.—Western Red-tailed Hawk. 
Not very common, and seen in the low valleys only in fall and winter. 
50. Archibuteo lagopus (Brunn.)., var. sancti-johannis.— Rough-legged Hawk. 
Coming down from the mountains in considerable numbers as fall approaches, and’ 
like the Duck Hawk, making its headquarters about the sloughs aud open sheets of 
water. Its chief dependence are mice, but it also seizes many wounded ducks. 
51. Aquila ckryscetus (L.).—Golden Eagle. 
Mr. Parker presented me with a specimen of this eagle, which he had killed in the 
fall near Carson. Its occurrence so low down is not common. 
52. Rhinogryphus aura { L.).—Red-headed Vulture. 
Numerous about Carson, where very useful as a scavenger. 
COLUMBIDJE. 
53. Zenaidura carolinensis (L.).—Carolina Dove. 
Abounds in the low valleys everywhere.
