Florida Scrub-Jays Are January Birds on the 2022 Audubon Calendar

Summary: Florida scrub-jays are January birds on the 2022 Audubon calendar by which the National Audubon Society announces vulnerable birds in the United States.

Juvenile versus mature stages, apart indistinguishabiliity during molting months from June through November, afford easier identifications than female versus male genders among Florida scrub-jays. Juvenile Florida scrub-jays are brown- or gray-headed and assume blue-feathered heads and upper bodies around six months after their birth. Mature, one-plus-year-old Florida scrub-jays attract attention with their black-blue bills and legs and with their blue-feathered heads, backs, rounded wings and long tails. All ages and both genders awaken predatory instincts in bobcats (Lynx rufus), Cooper's (Accipiter cooperii) and sharp-shinned (A. striatus) hawks, merlins (Falco columbarius), northern harriers (Circus cyaneus) and peregrine falcons (Falco peregrinus); male (lower) and female (upper) Florida Jays at American persimmon tree (Diospyros virginiana), illustrated by John James Audubon, The Birds of America, vol.

Florida scrub-jays, with populations 90 percent lower, are January birds on the 2022 Audubon calendar by which the National Audubon Society announces the current year’s 12 most vulnerable birds in North America.

Wintertime backyard feeders bring the Passeriformes (from Latin passer, “sparrow” and –fōrmēs, “-shaped”) perching-bird and songbird order member out from sand pine scrub subtropical forest ecoregions. That order’s Corvidae (from Latin corvus, “raven” and Greek -ειδής, “-like”) chough, crow, jackdaw, jay, magpie, nutcracker, raven, rook and treepie family member otherwise celebrates springtime. Breeding-season months from March through July direct them to 4- to 12-foot (1.22- to 3.66-meter) heights in palmetto, sand pine, shrubby oak and wild olive thickets.

Both parents-to-be establish 2- to 5-egg yearly broods in 9- to 10-centimeter (3.54- to 3.94-inch), rootlet-entwined inner-diameter, 18- to 20-centimeter (7.09- to 7.87-inch), oak-twig outer-diameter cups.

Twenty-eight- by 20-millimeter (1.102- by 0.787-inch) eggs feature heavier, larger ends more marked lilac-pink between and under cinnamon-rufous (brown-red, from Latin rūfus, “red”) blotches and spots.

The semi-glossy, smooth, somewhat elliptical eggs guard a greenness whose range goes from pea- to glaucous- (from Latin glaucus, from Greek γλαυκός, “blue-gray, blue-green”), to white-green. The male Florida-exclusive endemics (from Greek ἐν, “among” and δῆμος, “[one’s own] people”), often in loose, six-nest breeding and brooding colonies, handle food-hunting until eggs hatch. Female scrub-jays incubate their eggs for 17 to 19 days and then, during the 17- to 20-day nestling interval, interchange food-hunting responsibilities with their monogamous mates.

Agricultural land and residential and industrial property development jeopardize Florida scrub-jays, as January birds on the 2022 Audubon calendar, during breeding, incubating, nestling and fledgling months.

Yearling members of family-grouped Florida scrub-jays know about caring for altricial (helpless, from altrix, “[female] nourisher”), naked nestlings with white-yellow bills and legs and pink-red skin.

Their nestling siblings lack any back feathers their first four days and live with their eyes closed the first four to seven days in their nests. They migrate to nearby nests made for them by their parents 17 to 20 days after their births even as they master flight many days later. Their family nourishes them the first 110 days of 15-year lifespans nurtured by acorns, berries, insects, snails, spiders and, if need be, tiny amphibians and reptiles.

Florida scrub-jays, as 2022 Audubon calendar January birds, offer what their taxonomy, Aphelocoma coerulescens (from Greek ἀφελής, “simple” and κόμη, “hair” and Latin coerulēscēns, “blueing”) observes.

The central Florida species, presented by Louis-Augustin Guillaume Bosc d’Antic (Jan. 29, 1759-July 10, 1828), possesses brown-feathered heads as fledglings, gray-feathered as juveniles, blue-feathered as six-month-olds.

Mature stages quarter 9.1- to 11.5-inch- (23.11- to 29.21-centimeter-) lengths; rounded, 13- to 14.2-inch (33.02- to 36.07-centimeter) wingspans; and 2.3- to 3.3-ounce (65.2- to 93.55-gram) weights. They reveal gray-white foreheads; black eyelines; blue heads and long tails; black-blue bills, cheeks and legs; gray-white backs and upperparts; and blue-streaked gray-white breasts and throats. They seek food sources by branch- and ground-hopping and by swift, undulating, weak-gliding flights even as they sound aerial and land predator-specific, harsh, raspy alarm calls.

Kreep-tolling Florida scrub-jays, 2022 Audubon calendar January birds, tally perhaps 625 to 2,500 four-member families on 328.08-foot- (100-meter-) high, 22- to 24-acre (8.9- to 9.71-hectare) territories.

Central Florida firefighters and police officers aid Florida scrub-jays through their respective prescribed burns and traffic control. Habitat-threatened, hungry and juvenile Florida scrub-jays are not faster than speeding motorists or stronger than Florida sand pine scrub subtropical forest ecoregions assuming too thick configurations without regular, prescribed, firefighter-controlled burns or too thin configurations from developers clear-cutting scrubby, shrubby thickets. They appreciate not too thin, not too thick sand pines (Pinus clausa) with Adam's needle (Yucca filamentosa); American olive (Osmanthus americanus var. megacarpus); Chapman (Quercus chapmanii), myrtle (Q. myrtifolia), sand live (Q. geminata) and sandhill (Q. inopina) oak; cup lichens (Cladonia); eastern prickly pear (Opuntia humifusa); fetterbush (Lyonia lucida) and rusty staggerbush (L. ferruginea); flag-pawpaw (Asimina obovata); Florida rosemary (Ceratiola ericoides); garberia (Garberia heterophylla); saw (Serenoa repens) and scrub (Sabal etonia) palmetto; scrub holly (Ilex opaca var. arenicola); and silk bay (Persea humilis); Feb. 10, 2007, image of prescribed fire, south end, Merritt Island National Wildlife Refuge: U.S. Fish and Wildlife Service Southeast Region (USFWS/Southeast), CC BY 2.0 Generic, via Flickr
