Summary: Northern bobwhites are February birds on the 2022 Audubon calendar by which the National Audubon Society announces vulnerable birds in the United States.
Northern bobwhites are February birds on the 2022 Audubon calendar by which the National Audubon Society announces North American birds as extinct in the wild, critically endangered, endangered, vulnerable or near-threatened birds.
Female members of the Galliformes (from Latin gallus, “male chicken” and -fōrmēs, “-shaped”) landfowl order bear one-plus brood during each year’s breeding months, January through March. That order’s Odontophoridae (from Greek ὀδοντοφόρος, “toothed” and -ειδής, “-like”) New World quail family member congregates in 10- to 20-member coveys (from Latin cubō, I incubate”). One Caribbean, seven United Statesian and 15 Mexican subspecies design their ground-level nests in agricultural fields, brushy hedges, low-cover grasslands, mixed young forests and woodland edges.
All parents-to-be ease existing vegetation into hollow, shallow nests under healthy plants, for their annual, 7- to 28-egg clutch, double-brooded in the event of lost clutches.
Physically and sexually mature females furnish cream-white or dull white, semi-glossy, sub-elliptical to oval or pear-shaped, 30- by 24-millimeter (1.18- by 0.95-inch) eggs at one-day intervals.
Both parents-to-be get food-gathering and nest-guarding responsibilities during 23- to 24-day incubations of their smooth-shelled eggs and then during 14-day nestling periods of down-covered, open-eyed hatchlings. Their precocial (from Latin prae-, “before” and coquō, “I ripen” via praecox, “precocious, premature, ripe before its time, untimely”) hatchlings have buff-pink bills, feet and legs. They invoke buff-yellow-sided heads; buff-rufous (from Latin rūfus, “red”) foreheads; black eye-nape streaks; chestnut-red crowns and napes; buff-cream-striped, chestnut-red-banded mid-backs; black-, buff-, chestnut-mottled flanks; buff-gray undersides.
Northern bobwhites join the 2022 Audubon calendar as February birds whose free-range populations perhaps join edible seed-attracting insects, snails and spiders at seed-dispensing wintertime backyard feeders.
Six-year lifespans kindle nestlings keeping downy coats their first two weeks, first feathers for their first flights as 14-day-olds and first self-feeding as 21-day-old covey members.
Northern bobwhite nestlings lose their downy coats within two months of their hatching and lodge flight-friendly feathers as four- to eight-week-olds and full-grown bodies as two-month-olds. Dense monocultures of young trees menace low-cover, open-area brushy pastures, farmland borders, grassy roadsides, roadside brush and woodland edges that maintain northern bobwhites between mating seasons. Post-breeding fathers, mothers and their fledged seasonal broods need 10- to 20-member northern bobwhite coveys (from Latin cubō, “I recline” via Old French covee, “[egg] brood”).
The 2022 Audubon calendar observes northern bobwhites as February birds occupied with their eggs, hatchlings and nestlings; and with their breeding-season, non-breeding coveys and home ranges.
Northern bobwhites, presented scientifically as Colinus virginianus (from Spanish colín, “quail” and Latin Virginia and -ānus, “of, pertaining to”), perform short, startling, swift flights and glides.
Physical and sexual maturity queues 8- to 10-inch- (20- to 25-centimeter-) long bodies with 11- to 14-inch (28- to 35-centimeter) wingspans and with 6-ounce (175-gram) weights. Northern bobwhites, regarded taxonomically by Carl Linnaeus (May 23, 1707-Jan. 10, 1778), maturely reveal beige-, black-, brown-patterned heads; downward-curved, thick bills; fine-streaked breasts; and marked upper-parts. Black-and-white-faced, white-throated mature males tan-faced, tan-throated mature females sound hoi and hoi-lee calls to reunite dispersed flocks and bob-WHITE, bob-bob-WHITE and poor-bob-WHITE whistles during breeding-season months.
Caribbean, Central, North and South American hunters threaten northern bobwhites, as chicken-like, plump, tasty gamebirds that turn up as February birds on the 2022 Audubon calendar.
Northern bobwhites are low-cover, open-area residents of the eastern United States, southward to the Caribbean island of Cuba and through Estados Unidos Mexicanos (Mexico, "United Mexican States") and Guatemala; Geographical Distribution Map of Northern Bobwhite, June 27, 2018: Cephas, CC BY SA 4.0 International, via Wikimedia Commons |
