I haven’t seen this one at the feeder this year.  Maybe it’s early

Description
Blue jays are bright blue medium sized birds with blue head crests, black wing markings and black necklaces.
Life History
Bright and bold, blue jays often travel in noisy family groups in late summer and fall. Their arrival at a bird feeder tends to clear the area of smaller birds. Blue jays are known to eat the eggs and young of other birds and often frighten the adults off the nest by imitating the call of a hawk. Groups of blue jays often attack owls, which they consider a threat. 

Blue jays are one of the few birds that store food for use at another time. Blue jays eat insects and other invertebrates, small vertebrates including nestlings of other species, carrion, eggs, fruits and seeds. They use a number of behaviors to obtain food and defend themselves. In late summer, fall and winter they travel in large aggressive flocks that frighten other birds off of feeding areas and make predators think twice about bothering them. They use the call of hawks to frighten other birds. Females rarely leave the nest while incubating or rearing young. Males bring them food during this time.

Blue jays are generally unafraid of humans. In fact they have used human settlements in the west, with their resulting increase in food, water and vegetation, to expand their range. Most birdwatchers have mixed feelings about blue jays. They dislike their noisy aggressive behavior but appreciate their bold bright colors and cocky self assurance. In addition to their raucous, shrill side, jays can also emit a soft, low song and are unusually tame around humans.

Distribution
Blue jays are generally nonmigratory and are found throughout the eastern half of Texas, the U.S. and Canada. They have been expanding their range westward in urban and suburban areas due to habitat modification by humans.
Other
Early Texas folklore relates a tale of the blue jay being yoked to a plow by a sparrow. The mark left by the yoke can still be seen on the blue jay’s breast.

Blue Jays make a large variety of calls. The most often heard is a loudjeer, Also makes clear whistled notes and gurgling sounds. Blue Jays frequently mimic hawks, especially Red-shouldered Hawks.


This common, large songbird is familiar to many people, with its perky crest; blue, white, and black plumage; and noisy calls. Blue Jays are known for their intelligence and complex social systems with tight family bonds. Their fondness for acorns is credited with helping spread oak trees after the last glacial period.

  • Size & Shape

    Large crested songbird with broad, rounded tail. Blue Jays are smaller than crows, larger than robins.

  • Color Pattern

    White or light gray underneath, various shades of blue, black, and white above.

  • Behavior

    Blue Jays make a large variety of calls that carry long distances. Most calls produced while the jay is perched within a tree. Usually flies across open areas silently, especially during migration. Stuffs food items in throat pouch to cache elsewhere; when eating, holds a seed or nut in feet and pecks it open.

  • Habitat

    Blue Jays are birds of forest edges. A favorite food is acorns, and they are often found near oaks, in forests, woodlots, towns, cities, parks.

Cool Facts

  • Thousands of Blue Jays migrate in flocks along the Great Lakes and Atlantic coasts, but much about their migration remains a mystery. Some are present throughout winter in all parts of their range. Young jays may be more likely to migrate than adults, but many adults also migrate. Some individual jays migrate south one year, stay north the next winter, and then migrate south again the next year. No one has worked out why they migrate when they do.
  • Blue Jays are known to take and eat eggs and nestlings of other birds, but we don’t know how common this is. In an extensive study of Blue Jay feeding habits, only 1% of jays had evidence of eggs or birds in their stomachs. Most of their diet was composed of insects and nuts.
  • The Blue Jay frequently mimics the calls of hawks, especially the Red-shouldered Hawk. These calls may provide information to other jays that a hawk is around, or may be used to deceive other species into believing a hawk is present.
  • Tool use has never been reported for wild Blue Jays, but captive Blue Jays used strips of newspaper to rake in food pellets from outside their cages.
  • Blue Jays lower their crests when they are feeding peacefully with family and flock members or tending to nestlings.
  • At feeders in Florida, Red-headed Woodpeckers, Florida Scrub-Jays, Common Grackles, and gray squirrels strongly dominate Blue Jays, often preventing them from obtaining food.
  • The pigment in Blue Jay feathers is melanin, which is brown. The blue color is caused by scattering light through modified cells on the surface of the feather barbs.
  • The black bridle across the face, nape, and throat varies extensively and may help Blue Jays recognize one another.
  • The oldest known wild, banded Blue Jay lived to be at least 17 years 6 months old.
 

Habitat


Forest

Blue Jays are found in all kinds of forests but especially near oak trees; they’re more abundant near forest edges than in deep forest. They’re common in urban and suburban areas, especially where oaks or bird feeders are found.

Food

Omnivore

Blue Jays glean insects and take nuts and seeds in trees, shrubs, and on the ground; they also eat grains. They also take dead and injured small vertebrates. Blue Jays sometimes raid nests for eggs and nestlings, and sometimes pick up dead or dying adult birds. Stomach contents over the year are about 22 percent insect. Acorns, nuts, fruits, and grains made up almost the entire remainder. Of 530 stomachs examined, traces of bird eggs and nestlings were found in only 6 stomachs, although a search was specially made for every possible trace of bird remains. Blue Jays hold food items in feet while pecking them open. They store food in caches to eat later.

Nest Placement

Tree

Blue Jays build their nests in the crotch or thick outer branches of a deciduous or coniferous tree, usually 10-25 feet above the ground. Male and female both gather materials and build the nest, but on average male does more gathering and female more building. Twigs used in outer part of nest are usually taken from live trees, and birds often struggle to break them off. Birds may fly great distances to obtain rootlets from recently dug ditches, fresh graves in cemeteries, and newly fallen trees. Jays may abandon their nest after detecting a nearby predator.


Behavior


Ground Forager

This common, large songbird is familiar to many people, with its perky crest; blue, white, gray, and black plumage; and noisy calls. Blue Jays are known for their intelligence and complex social systems, and have tight family bonds. They often mate for life, remaining with their social mate throughout the year.

Only the female incubates; her mate provides all her food during incubation. For the first 8–12 days after the nestlings hatch, the female broods them and the male provides food for his mate and the nestlings. Female shares food gathering after this time, but male continues to provide more food than female.

Some individual nestlings begin to wander as far as 15 feet from the nest 1-3 days before the brood fledges. Even when these birds beg loudly, parents may not feed them until they return to the nest; this is the stage at which many people find an “abandoned baby jay.” If it can be restored to or near the nest, the parents will resume feeding it. The brood usually leaves the nest together usually when they are 17-21 days old. When young jays leave the nest before then, it may be because of disturbance. The jays are usually farther than 75 feet from the nest by the end of the second day out of the nest. Young remain with and are fed by their parents for at least a month, and sometimes two months. There is apparently a lot of individual variation in how quickly young become independent.

Blue Jays communicate with one another both vocally and with “body language,” using their crest. When incubating, feeding nestlings, or associating with mate, family, or flock mates, the crest is held down; the lower the crest, the lower the bird’s aggression level. The higher the crest, the higher the bird’s aggression level; when a Blue Jay squawks, the crest is virtually always held up.

Blue Jays have a wide variety of vocalizations, with an immense “vocabulary.” Blue Jays are also excellent mimics. Captive Blue Jays sometimes learn to imitate human speech and meowing cats. In the wild, they often mimic Red-shouldered and Red-tailed hawks, and sometimes other species.

Blue Jays are disliked by many people for their aggressive ways, but they are far less aggressive than many other species. In one Florida study, Red-bellied Woodpeckers, Red-headed Woodpeckers, Florida Scrub-Jays, Common Grackles, and gray squirrels strongly dominates Blue Jays at feeders, often preventing them from obtaining food, and Northern Bobwhites, Mourning Doves, White-winged Doves, Northern Mockingbirds, and Northern Cardinals occasionally dominated them as well. Sometimes Blue Jays mimic hawks when approaching feeders. This may deceive other birds into scattering, allowing the Blue Jay to take over the feeder, but most birds quickly return after the jay starts feeding.

Blue Jays carry food in their throat and upper esophagus—an area often called a “gular pouch.” They may store 2-3 acorns in the pouch, another one in their mouth, and one more in the tip of the bill. In this way they can carry off 5 acorns at a time to store for later feeding. Six birds with radio transmitters each cached 3,000-5,000 acorns one autumn.

Their fondness for acorns and their accuracy in selecting and burying acorns that have not been infested with weevils are credited with spreading oak trees after the last glacial period.

Despite being common, conspicuous birds that have been studied by many researchers, much about Blue Jays remains a mystery. This is the only New World jay that migrates north and south, and large flocks are observed flying over many hawkwatch spots, along shorelines, and at other migration overlooks, but their migration is very poorly understood. Some individuals remain year-round throughout their entire range, and at least some individuals depart during spring throughout their entire range except peninsular Florida. Migrating flocks can include adults and young birds, and recent analyses of movements of banded jays indicate that there is no age difference between jays that migrate and jays that remain resident. The proportion of jays that migrate is probably less than 20 percent.

Least Concern

Blue Jays do well around humans, and their populations are secure. The most frequent cause of death associated with humans comes from attacks by cats and dogs.
