All About Blue Jays Blue jays live on the edges of forests. They are also found in parts of cities, as well as oak trees. Sometimes people see them in the woods. You can see some in cities. Most Blue jays are in parks. Blue jays aren't the only jays out there. For example, the Stellers jay has less white in his wings. His head and chest are black with darker under parts. A Scrub-jay's crest and wings are solid blue, and its tail is white, black and barring. Blue jays usually build their nests in the hard outer branches of a deciduous or coniferous tree, 10-25 ft. above the ground. Both male and female gather the materials; however, the female builds the nest. Twigs that are used in the outer parts of the nest are usually taken from other …show more content…
Extensive study of Blue jays' feeding habits has shown that only 1% have evidence of eggs in their stomachs. Most diets were composed of insects and nuts. Blue jays feed on insects, nuts and seeds from shrubs and trees, and on the ground they also eat grain. They also sometimes pick up dying or dead adult birds. They also fond of fruits. Wheat is sometimes their best choice. The Blue jay makes all kinds of calls. They mostly make loud jeering noises. They also make whistling and gurgling sounds. Frequently they mimic hawks. They also sing something called the “Whisper song.” Blue jays communicate with each other vocally and with “body language” using their crest. When feeding nestlings, associating with their mate, family, or flock mates, or incubating, their crest is held down; the lower the crest the less aggression. The crest is usually held up when a Blue jay squawks. Only female Blue jays can incubate. The male, however, provides food for the incubation. The first 8-12 days after they hatch, the mother broods them while the male keeps providing food for his nestlings and mate. After some time, the female provides food with her
Of the birds of Arizona, the cactus wren is likely to be the most well known, as it is the state bird. The cactus wren is a very vocal bird with the white eye stripes behind each of it’s eyes. Its breast is heavily flecked with dark brown and black, whilst its tail feathers alternate between black, brown and white. Its beak also has a faint curve to it. The cactus wren makes its home in a variety of desert environments, most commonly in the foothills with all manner of scrub such as yucca, mesquite, and its namesake, cactus. One of the most numerous birds of the city is quail who tend to live in washes and bushes as they are often too heavily weighted to fly far off the ground or for long distances. The Northern mockingbird also

During the warm season (summer), piping plovers usually lives and nest on the sandy beaches, shores of the Great Lakes, major rivers, or the prairies. They usually breed on dry sandy beaches and in the winter, they settle along the shores of southeastern United States.
Sandhill Cranes are known for their courtship dances and their distinct loud calls. According to Northern Prairie Wildlife Research Center, there are a total of six subspecies of Sandhill Cranes that are classified into two groups; the migratory and non-migratory. “The three migratory subspecies (Lesser, Greater and Canadian) are distributed across a broad breeding range in the northern U.S. and Canada as well as eastern Siberia, with wintering grounds in the southern United States and northern Mexico. The three non-migratory subspecies (Mississippi, Cuban, and Florida) have restricted ranges in the southern United States and Cuba (International Crane Foundation).” According to Northern Prairie Wildlife Research Center, the declines in Sandhill Cranes are due to forfeiture of wetlands, changes in its environment, and hunting. Over the years, the debate is whether or not to hunt the bird. It is important that we preserve the Sandhill Cranes because they are not game birds, they’re beautiful birds, and they have cultural significance in other countries.
The jayhawk also known as Big Jay and his partner Baby Jay, definitely have a fun, memorable, and unique design. The jayhawk has evolved over many years but it has always had the colors blue, red, and yellow and the shoes which are meant for kicking opponents. In 1912, the first ever jayhawk was drawn by Henry Maloy, a cartoonist for the student newspaper. The jayhawk didn’t stay the same though, it has evolved over many years to the one everyone knows today. The University of Kansas website says, “By war's end, Jayhawks were synonymous with the impassioned people who made Kansas a Free State. In 1886, the bird appeared in a cheer--the famous Rock Chalk chant. When KU football players first took the field in 1890, it seemed only natural to call them Jayhawkers” (“The Jayhawk”). So not only does the jayhawk have a fun, memorable, and unique design, there is meaning behind

NOAA confirms blue whales can still be found in every part of the ocean today. The purple shaded space on the map shows where blue whales have been found
Language is commonly held to be the province of humans, but other inhabitants of earth possess their own forms of communication. Birds, dolphins, and whales are some of those that have a language. Primates also use vocal communication with each other. Their utterances have varied uses and volumes, with each primate’s voice being distinct just as human voices are. These unique calls have given researchers insight into the social workings of primate groups. The very fact that primates have a language offers insight into the evolution of language and calls into question what the term human truly means.

Areas, in western Ontario, and St. Lawrence River as well as in areas of the maritime provinces there is a high diversity of butterflies due to the deciduous woodlands. However with the diversity of butterflies in Canada, it is currently experiencing changes due to habitat disturbances like large timber and logging areas which affect the butterflies natural habitats, leading to a decrease in their survival and
After the blocks died out, pony bead seeds grew on the island. These very tiny seeds caused some difficulty for the birds studied. All finches, with the exception of Tosserus saladis, increased slight to moderately.
The large ground finches have a higher curve while the medium ground finches have a smaller head and a tiny beak. The place in which the finches live is what changes their appearances and also the weather helps decide the appearance of these finches.
When the colony becomes well established, the queen begins to lay some eggs that develop into queens and males. It takes a few years before a colony becomes large enough to send out winged males and young queens to start new colonies. The cycle will now begin all over again. Nests come in all shapes and sizes. One tropical species built a nest that extended forty feet below the surface of the ground.
Most peregrines are slate blue on the back and wings. The top of its head is black. Black
Alnut Kelber, Anna Balkenius, and Eric. J. Warrant studied the night-time vision of a nocturnal hawkmoth, Deilephila elpenor. They wanted to know if the hawkmoths can truly see colors at night, or if they are using other means to find the right kind of flowers to feed from. For example, humans cannot see colors at night and therefore have a harder time differentiating between objects using vision alone. However, a person could find food in a dark room using his or her other senses, such as smell or taste, or could rely on colorless vision to choose food based on its shape. The scientists tested a series of experiments to show that hawkmoths use color-vision at night, as opposed to reverting to their other senses like humans do.
