Great Egret (Ardea alba) Clip Art

. Great Egret (Ardea alba) Clip Art. Public Domain Clip Art Stock Photos and Images.

The Great Egret Ardea alba, also known as the Great White Egret, White Heron, or Common Egret, is a wading egret, found in most of the tropical and warmer temperate parts of the world, although it is very local in southern Europe and Asia. It is called Kōtuku in New Zealand. It is sometimes confused with the Great White Heron in Florida, which is a white morph of the Great Blue Heron.

The Great Egret is a large bird with all white plumage that can reach 3'3" in height and weigh up to 3.2 lb. It is only slightly smaller than the Great Blue or Grey Herons. Apart from size, the Great Egret can be distinguished from other white egrets by its yellow bill and black legs and feet. It also has a slow flight, with its neck retracted. This is characteristic of herons and bitterns, and distinguishes them from storks, cranes and spoonbills, which extend their necks.

Canada Goose (Branta canadensis),

Canada Goose (Branta canadensis)

Canada Goose (Branta canadensis)
Canada Goose From Wikipedia, the free encyclopedia

The Canada Goose (Branta canadensis), also referred to as the Canadian Goose, belongs to the Branta genus of geese, which contains species with largely black plumage, distinguishing them from the grey species of the Anser genus. The species name, canadensis, is a New Latin word meaning "of Canada"

The black head and neck with white "chinstrap" distinguish the Canada Goose from all except the Barnacle Goose, but the latter has a black breast, and grey, rather than brownish, body plumage..
There are seven subspecies of this bird, of varying sizes and plumage details, but all are recognizable as Canada Geese. Some of the smaller races can be hard to distinguish from the newly-separated Cackling Goose.

This species is 76-110 cm (30-43 in) long with a 127-180 cm (50-71 in) wing span. Males usually weigh 3.2–6.5 kg, (7–14 pounds), and can be very aggressive in defending territory. The female looks virtually identical but is slightly lighter at 2.5–5.5 kg (5.5–12 pounds), generally are 10% physically smaller than their male counterparts, and has a different honk. An exceptionally large male of the race B. c. maxima, the "giant Canada goose" (which rarely exceed 8 kg/18 lb), weighed 10.9 kg (24 pounds) and had a wingspan of 2.24 m (88 inches). The life span in the wild is 10-24 years.

By the early 20th century, over-hunting and loss of habitat in the late 1800s and early 1900s had resulted in a serious decline in the numbers of this bird in its native range. The Giant Canada Goose subspecies was believed to be extinct in the 1950s until, in 1962, a small flock was discovered wintering in Rochester, Minnesota by Harold Hanson of the Illinois Natural History Survey. With improved game laws and habitat recreation and preservation programs, their populations have recovered in most of their range,

Red-tailed Hawk From Wikipedia, the free encyclopedia

The Red-tailed Hawk (Buteo jamaicensis) is a medium-sized bird of prey, one of three species colloquially known in the United States as the "chickenhawk." It breeds almost throughout North America from western Alaska and northern Canada to as far south as Panama and the West Indies, and is one of the most common buteos in North America. There are fourteen recognized subspecies, which vary in appearance and range. It is one of the largest members of the genus Buteo in North America, weighing from 690 to 2000 grams (1.5 to 4.4 pounds) and measuring 45–65 cm (18 to 26 in) in length, with a wingspan from 110 to 145 cm (43 to 57 in). The Red-tailed Hawk displays sexual dimorphism in size, as females are 25% larger than males. Red-tailed Hawk plumage can be variable, depending on the subspecies. These color variations are called morphs, and a Red-tailed Hawk may be light, dark, or rufous.

The Red-tailed Hawk is successful in large part because it tolerates a wide range of habitats and altitudes, including deserts, grasslands, coniferous and deciduous forests, tropical rainforests, agricultural fields and urban areas. It lives throughout the North American continent, except in areas of unbroken forest or the high arctic.It is also legally protected in Canada, Mexico and the U.S. by the Migratory Bird Treaty Act of 1918.

Approximately 60% of all raptors under 1 year of age taken from the wild for use in American falconry are Red-tailed Hawks. The Red-tailed Hawk also has significance in Native American culture.
Its feathers are considered sacred by some tribes, and are used in religious ceremonies.

A male Red-tailed Hawk may weigh from 690 to 1300 grams (1.5 to 2.9 pounds) and measure 45–56 cm (18 to 22 in), while a female can weigh between 900 and 2000 grams (2 and 4.4 pounds) and measure 50–65 cm (20 to 26 in) in length. As is the case with many raptors the Red-tailed Hawk displays sexual dimorphism in size, as females are 25% larger than males. The wingspan is from 110 to 145 cm (43 to 57 in).

Red-tailed Hawk plumage can be variable, depending on the subspecies and the region. These color variations are morphs, and are not related to molting.

The western North American population, B. j. calurus, is the most variable subspecies and has three color morphs: light, dark, and intermediate or rufous. The dark and intermediate morphs constitute 10–20% of the population.

Though the markings and hue vary, the basic appearance of the Red-tailed Hawk is consistent. The underbelly is lighter than the back and a dark brown band across the belly, formed by vertical streaks in feather patterning, is present in most color variations. The red tail, which gives this species its name, is uniformly brick-red above and pink below. The bill is short and dark, in the hooked shape characteristic of raptors. The cere, the legs, and the feet of the Red-tailed Hawk are all yellow.

Immature birds can be readily identified at close range by their yellowish irises. As the bird attains full maturity over the course of 3–4 years, the iris slowly darkens into a reddish-brown hue. In both the light and dark morphs, the tail of the immature Red-tailed Hawk are patterned with numerous darker bars.

The American Robin (Turdus migratorius)

The American Robin (Turdus migratorius)

The American Robin (Turdus migratorius)
American Robin From Wikipedia, the free encyclopedia

The American Robin (Turdus migratorius) is a migratory songbird of the thrush family. The similarity between the orange-red coloring of its breast and that of the smaller and distantly related European Robin (Erithacus rubecula) led to its common name. It is widely distributed throughout North America, wintering south of Canada from Florida to central Mexico and along the Pacific Coast. It has seven subspecies, but only T. m. confinis in the southwest is particularly distinctive, with pale gray-brown underparts. It is the state bird of Connecticut, Michigan, and Wisconsin.
The American Robin is active mostly during the day and assembles in large flocks at night. Its diet consists of invertebrates (such as beetle grubs and caterpillars), fruits and berries. It is one of the first bird species to lay eggs, beginning to breed shortly after returning to its summer range from its winter range. Its nest consists of long coarse grass, twigs, paper, and feathers, and is smeared with mud and often cushioned with grass or other soft materials. It is among the first birds to sing at dawn, and its song consists of several discrete units that are repeated.

The adult Robin is preyed upon by hawks, cats, and larger snakes, but when feeding in flocks it is able to be vigilant and watch other birds for reactions to predators. Brood parasitism by the Brown-headed Cowbird occurs, but is rare because the Robin usually rejects the cowbird eggs.

Sparrow From Wikipedia, the free encyclopedia

The "true sparrows", the Old World sparrows in the family Passeridae, are small passerine birds. Generally, sparrows tend to be small, plump brown-grey birds with short tails and stubby yet powerful beaks. The differences between sparrow species can be subtle. They are primarily seed-eaters, though they also consume small insects. A few species scavenge for food around cities and, like gulls or pigeons, will happily eat virtually anything in small quantities. This family ranges in size from the Chestnut Sparrow (Passer eminibey), at 11.4 cm (4.5 inches) and 13.4 g., to the Parrot-billed Sparrow (Passer gongonensis), at 18 cm (7 inches) and 42 g. (1.5 oz).

The Old World true sparrows are found indigenously in Europe, Africa and Asia. In Australia and the Americas, early settlers imported some species which quickly naturalised, particularly in urban and degraded areas. House Sparrows, for example, are now found throughout North America, in every state of Australia except Western Australia, and over much of the heavily populated parts of South America.
