Overview
Florida Scrub-Jay: Medium, crestless jay with gray upperparts and underparts, blue head, and pale eyebrows. Throat is gray and breast has blue-gray streaks. The wings and tail are blue. Bill, legs and feet are black. Direct flight with steady bouyant wing beats. Glides between perches.
Range and Habitat
Florida Scrub-Jay: Restricted to scrublands across central Florida; found in dense growths of low oaks, myrtles, sand pines, palmettos, and thickets.
Crows and Jays (Corvidae)
ORDER
The crows, magpies and jays are one of the one hundred eighteen families of birds in the order PASSERIFORMES (pronounced pas-ser-i-FOR-meez); a large taxonomic order that includes larks, titmice, and wrens.
FAMILY TAXONOMY
The bird family that includes jays and crows, the Corvidae (pronounced COR-vi-dee), includes one hundred and twenty-six species in twenty-four genera found on all continents except for Antarctica.
NORTH AMERICA
There are forty species of Corvidae (often commonly called "Corvids") in ten genera that occur in North America (including the Hawaiian Crow, a species that has recently become extinct in the wild). Crows and ravens, raucous jays, long-tailed magpies and the Clark's Nutcracker of the high mountains are all members of this bird family.
KNOWN FOR
Members of the Corvidae are renowned for their intelligence and bold behavior. Among the smartest of birds, Common Ravens can be taught complicated tricks while the jays and nutcrackers have an amazing capacity to recall where they have cached food.
PHYSICAL
Generally medium-to-largish sized birds, Corvids such as the crows and Clark's Nutcracker have short, square tails while the tails of jays and magpies are long and graceful. All Corvids have stout, strong bills that work well for their omnivorous diet and strong legs and feet for a lifestyle both arboreal and terrestrial in nature.
COLORATION
Corvids are generally somber colored birds; the adult crows and ravens are all black while shades of gray, blue, brown, and black are the norm for other species. The exception is the Green Jay; a beautiful green and yellow bird with blue and black markings on the face.
GEOGRAPHIC HABITAT
Corvid species occupy every major habitat in North America from sun baked deserts to alpine meadows and Pacific coastal rain forests. While the Common Raven and American Crow can be found in these and other habitats, the Clark's Nutcracker and Pinyon Jay are restricted to western coniferous forests. The Steller's Jay occurs in the same evergreen forests but is replaced by different jay species in other forest types.
MIGRATION
Some of North America's hardiest bird species, only Blue Jays and American Crows fly south to escape the winter and even these are short distance migrations limited to birds that breed in regions with very harsh winters.
HABITS
Most Corvids are social, curious birds that forage in pairs or family groups that frequently communicate with harsh, rasping calls. Foraging takes place in the trees and on the ground and includes a variety of food items ranging from nuts to small animals and carrion.
CONSERVATION
Other than being susceptible to West Nile Virus, most Corvid species are fairly common, adaptable birds. Nevertheless, the Pinyon and Florida Scrub Jays are threatened by habitat loss and the Island Scrub Jay is of concern because the entire population is restricted to Santa Cruz Island off the California coast.
INTERESTING FACTS
The Clark's Nutcracker is so adapted to feeding on pine seeds that it has evolved a pouch under its tongue to store extra seeds while foraging. It caches the extra seeds at a variety of locations (many of which it amazingly remembers) and shares this knowledge with its mate. The "forgotten" seeds also help the propagation of more pine trees.
