This bird is named for the scaly appearance of its breast and back feathers. Along with its scaly markings, the bird is easily identified by its white crest that resembles a tuft of cotton.
The nest is typically a grass-lined hollow containing 9–16 speckled eggs. When disturbed, it prefers to run rather than fly.
Scaled quail occur from south-central Arizona, northern New Mexico, east-central Colorado,[3] and southwestern Kansas south through western Oklahoma and western and central Texas into Mexico to northeastern Jalisco, Guanajuato, Queretaro, Hidalgo, and western Tamaulipas. It has been introduced to Cuba, Jamaica, Haiti, Dominican Republic, Puerto Rico and to the United States in Hawaii, central Washington, eastern Nevada, and Nebraska, but is only considered established in central Washington and eastern Nevada.[4][5]
Scaled quail has formed several subspecies, 3 of which range into the USA:
Callipepla squamata pallidaBrewster, 1881 (northern scaled quail). The most common subspecies, it occurs from Arizona and New Mexico to Colorado and just into Oklahoma, and western Texas, northern Chihuahua, and Sonora. It is paler than the nominate subspecies.
Callipepla squamata hargraveiRea, 1973 (Upper Sonoran scaled quail).[3] A form of arid habitat, it is only found in the area where the states of Colorado, Kansas and Oklahoma meet, and in northwestern New Mexico. It is the palest subspecies, adapted to dry and sandy habitat.
Callipepla squamata castanogastrisBrewster, 1883 (chestnut-bellied scaled quail). Found in southern Texas from Eagle Pass and San Antonio south to adjacent northwestern Mexico (Coahuila, Nuevo León, and Tamaulipas). Similar individuals are sometimes found in the extreme northeast and west of the species' range.[7] The chestnut brown belly distinguishes it from all other subspecies; it is also darker than the other two found in the USA.
Plant communities
According to Ligon,[8] the distribution of scaled quail is largely coextensive with mesquite (Prosopis spp.), condalia (Condalia spp.), and cholla (Cylindropuntia spp.).
In Oklahoma, scaled quail occur in sand sagebrush (Artemisia filifolia)-grassland, pinyon-juniper (Pinus spp.-Juniperus spp.), and shortgrass High Plains.[9][10] Sand sagebrush-grasslands include sand sagebrush, soapweed yucca (Yucca glauca), skunkbush sumac (Rhus trilobata), and sand plum (Prunus watsonii).[10] Scaled Quail in Oklahoma inhabit rough or rolling land, especially where sagebrush (Artemisia spp.), mesquite, cactus (Opuntia spp. and others), yucca (Yucca spp.), juniper, sand shinnery oak (Quercus havardii), and rocks furnish cover.[11]
In Colorado, scaled quail occupy sand sagebrush and/or yucca stands on sandy soils.[12] The cover types used by scaled quail in Colorado are, in descending order, sand sagebrush-grassland, pinyon-juniper, dense cholla-grassland, dryland farmland, irrigated farmland, and greasewood (Sarcobatus spp.)-saltbush (Atriplex spp.) washes. Scaled Quail made little or no use of sparse cholla-grassland, riparian areas, reseeded grasslands, or shortgrass prairie disclimax.[13]
Timing of major life events
In Arizona, pairing and maximum dispersal is complete by mid-June. Nesting probably does not begin until early July.[14] In Oklahoma, egg laying usually starts in late April. Completed clutches have been found as early as May 8.[11] Egg laying occurs from March to June in Texas and Mexico, and from April to September in New Mexico. Nests with eggs were reported as early as April 15 in New Mexico.[10]
Scaled quail lay from 9 to 16 eggs; most clutches are 12 to 14 eggs.[15] Eggs are incubated by the female for 21 to 23 days. Double-brooding (the production of two consecutive broods in one season) is common.[15] In west Texas, Wallmo [16] observed the male rearing the first brood while the female began a second clutch. Sutton [11] stated, however, that scaled quail in Oklahoma are probably single-brooded, but have hatched broods as late as September 6. Ehrlich and others [17] also list scaled quail as single-brooded.
The precocial young leave the nest shortly after hatching. They are accompanied by at least one, usually both, parents, who show them how to find food.[17] The young fledge rapidly (age at fledging not reported in the literature), and are adult size in 11 to 15 weeks.[6][17]
Scaled quail are fairly sedentary. The winter home ranges of scaled quail coveys varied from 24 to 84 acres (9.7 to 34.0ha). The home ranges of separate coveys overlap only slightly or not at all.[6][10] From September to November scaled quail coveys maintain stable territories.[10][14] In Arizona, 75 to 90% of a population apparently moved off of a breeding area by mid-November, moving to nearby mountain foothills. The mountain habitat was consistent with that found on the breeding area. In March the population on the breeding area increased again, with most birds in groups of four to eight.[14]
The average winter covey size for scaled quail is around 30 birds, although coveys of up to 150 birds have been reported.[17]
Preferred habitat
Scaled quail inhabit dry, open valleys, plains, foothills, rocky slopes, draws, gullies, and canyons that have a mixture of bare ground, low herbaceous growth, and scattered brushy cover.[9][17] Good scaled quail habitat is characterized by low-growing grasses with forbs and shrubs. Overall ground cover is between 10 and 50%. Trees and shrubs should be less than 6.6 feet (2.0m) tall. Scaled quail avoid the dense growth associated with streamsides. Transmitter-fitted scaled quail had individual home range sizes of 52 and 60 acres (21 and 24ha).[14]
An absolute requirement by scaled quail for a source of open water has not been established; there is some debate in the literature whether there is such a requirement.[6][10] Scaled quail have been reported as inhabiting an area 7 or 8 miles (11 or 13 kilometres) from the nearest water in Arizona. In New Mexico, it was not unusual to find Scaled Quail 10 to 15 miles (16 to 24 kilometres) from water.[10] Wallmo [16] observed winter coveys 3 and 7 miles (4.8 and 11.3 kilometres) from water in Big Bend National Park in southwestern Texas.
In Arizona, scaled quail summer habitat is seldom within 660 feet (200m) of water. Scaled quail were observed drinking at stock tanks from April to June (which was a dry period during the course of the study) every 2 to 3 days.[14] In Oklahoma, scaled quail often migrate to farms and ranches in winter and are thus closer to a source of water in winter than in summer.[10] DeGraaf and others [9] reported that in winter, scaled quail are usually found within 1.25 miles (2.01km) of a source of water.
Cover requirements
Feeding cover: scaled quail use grass clumps and shrubs for cover while feeding. In one study they were frequently seen crossing 82 to 165 feet (25 to 50 metres) of bare ground. When disturbed, scaled quail hid in snakeweed (Gutierrezia spp.) or in grass clumps.[14] In June and July foraging occurs on open grasslands which are not used at other times.[10]
Loafing cover: scaled quail coveys occupy loafing or resting cover after early morning feeding periods. Scaled quail occupy desert grassland or desert scrub with a minimum of one loafing covert per approximately 70 acres (28 hectares).[9][15][18] In northwestern Texas, loafing coverts were characterized by: (1) overhead woody cover, (2) lateral screening cover, (3) a central area with bare soil, and (4) one or more paths through the lateral cover. Covert heights ranged from 1.6 to 5.9 feet (0.49 to 1.80m) high and 2.6 to 6.9 feet (0.79 to 2.10m) in diameter. Cholla formed all or part of the overhead cover of 85% of coverts, even though they were dominant at only 12% of the study locations. In areas where scaled quail occur without cholla, woody species such as wolfberry (Lycium spp.) and mesquite are important for overhead cover.[19] In Oklahoma pinyon-juniper habitats, scaled quail use the shade of tree cholla (Cylindropuntia imbricata) and human-made structures.[10] In Arizona, scaled quail occupied wolfberry and mesquite 1.7 to 5 feet (0.52 to 1.52m) tall for loafing cover. This overhead cover provides midday shade, but is open at the base to allow easy escape from predators.[14] In Oklahoma, winter home ranges always contained skunkbush sumac, tree cholla, or human-made structures providing overhead cover.[10]
Night-roosting cover: scaled quail roosts were observed in yucca (Yucca angustifolia), tree cholla, and true mountain-mahogany (Cercocarpus montanus)-yucca-fragrant sumac (Rhus aromatica) vegetation types. The height of vegetation used for night roosts was less than 1.6 feet (0.49m).[20]
Nesting cover: In March or April winter coveys spread out into areas with less cover. This use of areas with less cover coincides with a seasonal decrease in the number of raptors in the same area.[10] Scaled quail nests are constructed under tufts of grasses, and are sheltered by sagebrush (Artemisia spp.), creosotebush (Larrea tridentata), mesquite, catclaw acacia (Acacia greggii), cactus, or yucca;[15] under dead Russian-thistle (Salsola kali), mixed forbs, or soapweed yucca; or sheltered in old machinery or other human-made debris.[11] In Oklahoma, 66% of nests were in one of four situations: (1) dead Russian-thistle, (2) machinery and junk, (3) mixed forbs, and (4) soapweed yucca.[10] In New Mexico, ordination of breeding birds and vegetative microhabitats indicated that scaled quail were associated with increased levels of patchiness and increased cover of mesquite and cactus.[21]
Food habits
Scaled quail are opportunistic eaters.[6] Seeds are consumed year-round. Large seeds (such as those of mesquite and snakeweed) are important in Scaled quail diets.[22] Other seeds include those of elbowbush (Forestiera angustifolia), catclaw acacia, mesquite, hackberry (Celtis spp.), Russian-thistle, rough pigweed (Amaranthus retroflexus), and sunflowers, ragweeds (Ambrosia spp.), and other Asteraceous plants.[9] Scaled quail consume more grass seeds than do other quail species.[9] Other dietary components include leaves, fruits, and insects. Summer diets are high in green vegetation and insects, which are also important sources of moisture.[14]
In Oklahoma, small groups of scaled quail feed among soapweed yucca and in soapweed yucca-sand sagebrush ranges, weed patches, and grain stubble. Also in Oklahoma, early winter foods apparently eaten when other foods are not available included snow-on-the-mountain (Euphorbia marginata), sand paspalum (Paspalum stramineum), field sandbur (Cenchrus pauciflorus), purslane (Portulaca spp.), skunkbush sumac, Fendler spurge (Euphorbia fendleri), and leaf bugs. Jimsonweed (Datura stramonium) and juniper berries were always avoided.[10] Winter foods of the scaled quail in Oklahoma include Russian-thistle and sunflower (Helianthus spp.) seeds.[11]
In northwestern Texas, selection of foods by scaled quail was dependent on foraging techniques, availability, and seed size. Small seeds were selected when they were still on the plant and could be easily stripped, but were not eaten once they had fallen, presumably because they were too small and/or too hard to find. Broom snakeweed (Gutierrezia sarothrae) was a staple in winter diets; it was not highly selected but was consumed in proportion to its availability (and lack of availability of choice items).[23] Generally, in Texas grass seeds (mainly tall dropseed [Sporobolus asper] and rough tridens [Tridens muticus]) were major constituents of scaled quail diets. This was attributed to a precipitation pattern that resulted in a relatively higher amount of grass seed available, and a lower amount of available forbs. In the same study green vegetation formed a higher proportion of the diet than reported for other areas.[24]
In southwestern Texas, chestnut-bellied scaled quail consumed woody plant seeds and green vegetation. The seeds of brush species comprised 68% of the contents of 32 scaled quail crops. Green food, chiefly wild carrot (Daucus carota) and clover (Trifolium spp.) made up 7.17%. Elbowbush was the single most important source, followed by Roemer acacia (Acacia roemeriana), desert-yaupon (Schaefferia cuneifolia), and spiny hackberry (Celtis pallida).[25]
In southeastern New Mexico, staples (comprising at least 5% of scaled quail diet in both summer and winter) were mesquite and croton (Croton spp.) seeds, green vegetation, and snout beetles. Nonpreferred foods eaten in winter and available but not consumed in summer included broom snakeweed (the main winter food), crown-beard (Verbesina encelioides), cycloloma (Cycloloma atriplicifolium), and lace bugs. Mesquite seeds and broom snakeweed seeds together made up 75% of the winter diet.[22]Grasshoppers were a summer staple. Insect galls, cicadas, scarab beetles, spurge (Euphorbia spp.), plains bristlegrass (Setaria macrostachya) seeds, and white ratany (Krameria grayi) were consumed in a less pronounced seasonal pattern.[22] Another study reported substantial amounts of prairie sunflower seeds (Helianthus petiolaris) and pigweed (Amaranthus spp.) seeds in the diet of scaled quail.[26]
Scaled quail feed in alfalfa (Medicago spp.) fields.[11]
Predators
In Arizona, potential scaled quail predators include mammals, birds, and reptiles. Most scaled quail kills are made by avian predators including northern harrier (Circus cyaneus), red-tailed hawk (Buteo jamaicensis), American kestrel (Falco sparverius), prairie falcon (Falco mexicanus), and great horned owl (Bubo virginianus).[14] In New Mexico, predators on scaled quail include hawks, owls, coyote (Canis latrans), and snakes.[18] In Colorado, potential predators of scaled quail include coyote, gray fox (Urocyon cinereoargenteus), red fox (Vulpes vulpes), kit fox (V. velox), bobcat (Lynx rufus), northern harrier, rough-legged hawk (Buteo lagopus), prairie falcon, peregrine falcon (Falco peregrinus), American kestrel, golden eagle (Aquila chrysaetos), and bald eagle (Haliaeetus leucocephalus).[12]
The greater sage-grouse, also known as the sagehen, is the largest grouse in North America. Its range is sagebrush country in the western United States and southern Alberta and Saskatchewan, Canada. It was known as simply the sage grouse until the Gunnison sage-grouse was recognized as a separate species in 2000. The Mono Basin population of sage grouse may also be distinct.
The Western Gulf coastal grasslands are a subtropical grassland ecoregion of the southern United States and northeastern Mexico. It is known in Louisiana as the "Cajun Prairie", Texas as "Coastal Prairie," and as the Tamaulipan pastizal in Mexico.
Gambel's quail is a small ground-dwelling bird in the New World quail family. It inhabits the desert regions of Arizona, California, Colorado, New Mexico, Nevada, Utah, Texas, and Sonora; also New Mexico-border Chihuahua and the Colorado River region of Baja California. Gambel's quail is named in honor of William Gambel, a 19th-century naturalist and explorer of the Southwestern United States.
Cassin's sparrow is a medium-sized sparrow.
Ord's kangaroo rat is a kangaroo rat native to western North America, specifically the Great Plains and the Great Basin, with its range extending from extreme southern Canada to central Mexico.
The East Potrillo Mountains are a mountain range in south central Doña Ana County, New Mexico. They are located approximately 25 miles (40 km) west of El Paso, Texas, 30 miles (48 km) southwest of Las Cruces, New Mexico, and 30 miles east of Columbus, New Mexico. The southern tip of the range is less than 5 miles (8.0 km) from the Mexican border. The mountains and most of the surrounding acreage are located on land owned by the Bureau of Land Management. Access to the general vicinity is through New Mexico State Road 9, and several unpaved county roads.
The white-throated woodrat is a species of rodent in the family Cricetidae. It is found from central Mexico north to Utah and Colorado in the United States. It is primarily a western species in the United States, extending from central Texas west to southeastern California. Populations east of the Rio Grande in New Mexico and Trans-Pecos Texas, previously considered to be variants of the white-throated woodrat, have since 1988 been assigned to the white-toothed woodrat.
The brush mouse is a species of rodent in the family Cricetidae. It is found in mountainous areas of Mexico and the western United States at altitudes over 2,000 m (6,600 ft).
The elegant quail is a species of New World quail endemic to Pacific-slope thorn forest of north-western Mexico, from southern Sonora to Nayarit. These are common, mainly ground-dwelling birds, and the IUCN has rated them as being a "species of least concern".
Gutierrezia sarothrae is a species of flowering plant in the family Asteraceae known by the common names broom snakeweed, broomweed, snakeweed, and matchweed. It is a subshrub native to much of the western half of North America, from western Canada to northern Mexico, and can be found in a number of arid, grassland, and mountain habitats. It can be toxic to livestock in large quantities, due mainly to the presence of saponins.
The black-tailed jackrabbit, also known as the American desert hare, is a common hare of the western United States and Mexico, where it is found at elevations from sea level up to 10,000 ft (3,000 m). Reaching a length around 2 ft (61 cm), and a weight from 3 to 6 lb, the black-tailed jackrabbit is one of the largest North American hares. Black-tailed jackrabbits occupy mixed shrub-grassland terrains. Their breeding depends on the location; it typically peaks in spring, but may continue all year round in warm climates. Young are born fully furred with eyes open; they are well camouflaged and are mobile within minutes of birth, thus females do not protect or even stay with the young except during nursing. The average litter size is around four, but may be as low as two and as high as seven in warm regions.
Cottonwood Canyon Wilderness is a 11,712-acre (47.4 km2) wilderness area in the US state of Utah. It was designated March 30, 2009, as part of the Omnibus Public Land Management Act of 2009. Located adjacent to the southern edge of the Dixie National Forest, it encompasses and protects a transition zone between the Colorado Plateau to the east and the Mojave Desert to the west. It is bordered by the Cottonwood Forest Wilderness to the northeast and is itself a part of the Red Cliffs National Conservation Area.
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a biome found mid-elevations in arid regions of the Western United States, characterized by being an open forest dominated by low, bushy, evergreen junipers, pinyon pines, and their associates. At lower elevations, junipers often predominate and trees are spaced widely, bordering on and mingling with grassland or shrubland, but as elevation increases, pinyon pines become common and trees grow closer, forming denser canopies. Historically, pinyon-juniper woodland provided a vital source of fuel and food for indigenous peoples of the American Southwest. The nuts continue to be a traditional indigenous food, and because nut-collecting was also adopted by the Spanish in the 1500s, the nuts are also traditionally harvested by some Hispanic communities.
Sporobolus cryptandrus is a species of grass known as sand dropseed. It is native to North America, where it is widespread in southern Canada, most of the United States, and northern Mexico.
Calamovilfa longifolia is a species of grass known by the common names prairie sandreed and sand reedgrass. It is native to North America, where it occurs from the Northwest Territories to Ontario in Canada and as far south as New Mexico and Kansas in the United States. There are two varieties, var. longifolia being widespread in the species' range and var. magna being native to the Great Lakes region.
Artemisia filifolia, known by common names including sand sagebrush, sand sage and sandhill sage, is a species of flowering plant in the aster family. It is native to North America, where it occurs from Nevada east to South Dakota and from there south to Arizona, Chihuahua, and Texas.
The Datil Mountains are a small range on the northern edge of the Mogollon-Datil volcanic field, just northwest of the Plains of San Agustin in the U.S. state of New Mexico. The range lies in Socorro and Catron Counties, north of the town of Datil, New Mexico and takes its name from the Spanish word for “date,” dating back over two hundred years. In The Place Names of New Mexico, Robert Julyan suggests two possible explanations for the name: 1) that “the seedpods of the broad-leafed yucca sufficiently resembled dates” or 2) “the Spanish applied the name to the fruit of the prickly pear cactus.” The area includes the major ridgeline of Madre Mountain, which is sacred ground to the Acoma, Laguna, and Zuni tribes, as well as several other unnamed peaks and ridges. US Highway 60 crosses the Datil Mountains between the towns of Datil and Pie Town.
The Colorado Plateau shrublands is an ecoregion of deserts and xeric shrublands in the Western United States.
The Meseta Central matorral is a deserts and xeric shrublands ecoregion in north-central Mexico.
