272. American golden plover. Charadrius dominicus. Migrant, not common; same record as preceding.
273. Killdeer. Ægialitis vocifera. Abundant summer resident; arrives early in spring; breeds most abundantly on plains and at base of foothills, but is far from rare at an altitude of 10,000 feet.
274. Semipalmated plover. Ægialitis semipalmata. Migrant, not common; breeds near the Arctic Circle.
281. Mountain plover. Ægialitis montana. Common summer resident; in spite of its name, a bird of the plains rather than the mountains; yet sometimes found in parks at an altitude of 8,000 and even 9,000 feet. Its numbers may be estimated from the fact that in one day of August a sportsman shot one hundred and twenty-six birds, though why he should indulge in such wholesale slaughter the author does not understand.
283. Turnstone. Arenaria interpres. Rare migrant; breeding grounds in the north; cosmopolitan in range, but chiefly along sea-coasts.
289. Bob-white. Colinus virginianus. Resident; somewhat common locally; good reason to believe that all the quails of the foothills are descendants of introduced birds, while those of the eastern border of the plains are native. A few were introduced some years ago into Estes Park, and are still occasionally noticed.
293. Scaled partridge. Callipepla squamata. Resident; common locally; southern species, but more common than the bob-white at Rocky Ford, Col.
294. California partridge. Lophortyx californicus. Resident, local; introduced at Grand Junction, Col., and have flourished so abundantly as to become troublesome to gardeners.
295. Gambel's partridge. Lophortyx gambelii. Resident, rare; known only in southwestern part of the State; a western species.
297. Dusky grouse. Dendragapus obscurus. Resident; mountain dwellers; breed from 7,000 feet to timber-line; in September wander above timber-line to 12,500 feet, feeding on grasshoppers; remain in thick woods in winter.
