248. =Sanderling.= CALIDRIS ARENARIA. Rare migrant, on plains; range nearly cosmopolitan; breeds only in northern part of northern hemisphere.

249. =Marbled godwit.= LIMOSA FEDOA. Migrant; not common; a bird of the plains, but seldom seen; occasionally found in the mountains.

254. =Greater yellow-legs.= TOTANUS MELANOLEUCUS. Common migrant; in favorable localities below 8,000 feet.

255. =Yellow-legs.= TOTANUS FLAVIPES. Common migrant; distribution same as preceding.

256. =Solitary sandpiper.= HELODROMAS SOLITARIUS. Summer resident; not common; in migration, common; breeds from plains to 10,000 feet.

258a. =Western willet.= SYMPHEMIA SEMIPALMATA INORNATA. Summer resident; not common; common migrant, especially in the fall; breeds from plains to 7,000 feet.

261. =Bartramian sandpiper.= BARTRAMIA LONGICAUDA. Common summer resident; abundant in migration; a bird of the plains; rare west of mountains.

263. =Spotted sandpiper.= ACTITIS MACULARIA. Abundant summer resident; breeds on the plains and at all intermediate altitudes to 12,000 feet, even on top of mountains of that height, if a lake or pond can be found; in fall, ranges above timber-line to 14,000 feet; some may remain throughout winter.

264. =Long-billed curlew.= NUMENIUS LONGIROSTRIS. Common summer resident; breeds on the plains; also in Middle and South Parks; found on both sides of the range.

265. =Hudsonian curlew.= NUMENIUS HUDSONICUS. Rare migrant; all records thus far from the plains; general range, North America.

270. =Black-bellied plover.= SQUATAROLA SQUATAROLA. Migrant, not common; bird of plains below 5,000 feet; breeds far north.

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.

300b. =Gray ruffed grouse.= BONASA UMBELLUS UMBELLOIDES. Rare resident; a more northern species, but a few breed in Colorado just below timber-line; winters in higher foothills.

304. =White-tailed ptarmigan.= LAGOPUS LEUCURUS. Common resident; one of the most strictly alpine species; breeds entirely above timber-line from 11,500 to 13,500 feet; thence ranging to the summits of the highest peaks. Only in severest winter weather do they come down to timber-line; rarely to 8,000 feet. In winter they are white; in summer fulvous or dull grayish-buff, barred and spotted with black. This bird is colloquially called the "mountain quail." The brown-capped leucosticte is the only other Colorado species that has so high a range.

305. =Prairie hen.= TYMPANUCHUS AMERICANUS. Resident; uncommon and local.

308b. =Prairie sharp-tailed grouse.= PEDIOECETES PHASIANELLUS CAMPESTRIS. Resident, not common; once common, but killed and driven out by pothunters; some breed in Middle Park; noted in winter at 9,500 feet.

309. =Sage grouse.= CENTROCERCUS UROPHASIANUS. Common resident. "As its name implies, it is an inhabitant of the artemisia or sage-brush plains, and is scarcely found elsewhere." Ranges from plains to 9,500 feet.

310. =Mexican turkey.= MELEAGRIS GALLOPAVO. Rare local resident; southern part of the State.

310a. =Wild turkey.= MELEAGRIS GALLOPAVO FERA. Resident; rare; once abundant, but will probably soon be exterminated; not certain whether Colorado birds are eastern or western forms.
