Wood Stork

 

The Life of Animals | Wood Stork | The adult is a large bird that is 83-115 cm (33-45 inches) tall and extends 140-180 cm (58-71 in) across the wings. Males weigh 2.5 to 3.3 kg (5.5 to 7.3 pounds), females weighing 2.0 to 2.8 kg (4.4 to 6.2 pounds) but big males can weigh up to 4.5 kg (10 lbs). The head is dark brown with a bald face, black, and the bill is dark yellow thick downcurved. The bare head and long beak, which can measure up to 25.5 cm (10.0 inches) long, the wood stork characteristic of other waders of its range. It is a tropical and subtropical species, which reproduces much of South America, Central America and the Caribbean. The wood stork is the only stork that breeds in North America today. In the United States there is a small breeding population and endangered in Florida, Georgia and South Carolina, along with a newly discovered colony in southeastern North Carolina.



The Wood Stork is a broad winged bird that flies upward with outstretched necks and legs outstretched. It usually feeds the lower water levels concentrate fish in open wetlands, but also frequents rice fields. Taking the peak fish open water until a fish is detected. In the United States. Wood Stork favors cypress swamps, marshes, or (less often) in the mangrove habitat and close. State emergency Wood Stork led to the salvation of the small rural town of Colquitt, Georgia. Plans include a new bridge over Spring Creek and Colquitt around wetlands. However, the residence of the Wood Stork in the swamp forests of Southwest Georgia DOT must use the existing bridge in Colquitt.


A resident breeder in lowland wetlands with trees, the stork builds a large stick nest in a tree in the forest. Colonial nesting with a maximum of 25 nests in a tree. The competition for food is fierce, and if food is scarce, only surviving older chickens. Week of chicks fed 15 times a day and growing rapidly. During the mating season, wood storks need more than 400 pounds (180 kg) of fish to feed themselves and their young. In a time when young people are 4 weeks old, the parents leave the nest in search of food, and this continues until the chicks "farm" or leave the nest. Each adult will defend their nest from predators varied. Raccoons are the main predators of nests, and can cause kidney nesting colony almost complete when the water dries under nests in dry years, as they can easily access the nest with dry earth under the tree.



A fossil fragment found at Touro Passo Formation Arroio Touro Passo (Rio Grande do Sul, Brazil) may be living species, is found in most of the late Pleistocene, about 10,000 s of years. The North American fossils are from extinct relative of a larger M. wetmorei. This was probably a sister species, occurred sympatrically in Cuba in the late Pleistocene

African Penguin

  
The Life of Animals | African Penguin | African penguins grow 68-70 cm (26.7 to 27.5 in) tall and weigh between 2 and 5 kg (4.4 and 11 lbs), you have a single black stripe and black spots on the chest, pattern of dots for each penguin, like human fingerprints. The African Penguin is on the southwest coast of Africa, living in colonies on 24 islands between Namibia and Algoa Bay, near Port Elizabeth, South Africa. It 'the only penguin species that breeds in Africa and his presence gave the name of the islands Penguin. Mainland colonies probably only recently due to the reduction in the number of possible predators, although Betty's Bay colony has been attacked by leopards.


Boulders Beach is a tourist attraction for swimming beach, and penguins. African penguins feed on the open sea, where they pursue pelagic fish such as sardines and anchovies (Engraulis capensis for example) and marine invertebrates such as squid and small crustaceans consume a penguin up to 540 grams of prey can every day, but this increases above 1 kg when lifting the African penguin chicks elderly is monogamous. Chicks fledge at 60 to 130 days. When penguins outline, are not able to feed their new feathers are not waterproof yet, so that rapidly throughout the moult, which lasts about 20 days of African penguins


The average lifespan of an African penguin is 10 to 27 years in the wilderness, and perhaps longer in captivity. However, the African penguin can often fall thieves. Their predators are sharks in the sea, Cape seals and occasionally killer whales. Land-based enemies include mongoose, Genets, domestic cats, and the Kelp Gull stealing their eggs and newly hatched chicks The African Penguin is a species of which the Agreement on the Conservation of African-Eurasian migratory waterfowl (AEWA) applies. The African penguin in the Red Book of the data listed as a species in danger of extinction.


In September 2010, the African penguin was listed as endangered under the laws of the United States Endangered Species. 5,000 breeding pairs estimated to live in Namibia in 2008, in 2009, about 21,000 pairs were estimated to live in South Africa

Black Swan

 

The Life of Animals | Black Swan | Black swans, primarily black-feathered birds with white feathers. Cygnets (immature birds) are a greyish-brown with pale-edged feathers. Mature Black Swan measures 110-142 cm (43 and 56 inches) in length and weighing 3.7 to 9 kg (8.2 to 20 pounds). The neck is long (relatively long neck swans) and curved in the "S" shape. Black Swan says the musical and far reaching bugle sound, called either on the water or in the air, and a number of soft humming note. When swimming, Black Swans hold their necks arched or erect, and often carry their feathers or wings raised in an aggressive display. Black Swan is unlike any other Australian bird, but can be confused in flight in low light conditions and at great distances from the Magpie goose can. However, Black Swan can be distinguished by a much longer neck and slower wing beat


Before the arrival of the Maori in New Zealand, a subspecies of Black Swan, as the New Zealand Swan became known in the islands, but it was obvious exterminated. In 1864, the Australian Black Swan was introduced to New Zealand as an ornamental waterfowl, and populations are now at large coastal or inland waters, especially in the Rotorua Lakes, Lake Wairarapa and Lake Ellesmere, and the spread of Chatham Islands. Black Swan is almost exclusively herbivorous, and while there are some regional and seasonal changes, diet, usually caused by water and marsh plants dominated. The exact composition varies depending on the water level at high tide, where normal foods are out of reach Black Swans will feed on pasture plants on shore. The Black Swan feeds in the same way in the other swans.


Black Swans are also able to filter feed on the surface, like the other swans, black swan mostly monogamous, mating for life (about 6% divorce rate). Typically, black swans nest in wet winter (February to September), sometimes in large colonies. Black Swan nest much larger heap or mound of reeds, grasses and weeds between 1 and 1.5 meters (3-4 ½ feet) in diameter and up to 1 meter in shallow water or on islands nest again every year, restored or rebuilt as necessary. Both sexes incubate the eggs, with the female incubating at night. If the egg is accidentally roll out of the nest egg of both sexes from the neck (in other swan species only the female performs this feat).


Like all swans Black Swans will actively defend their nests with their wings and beaks. After hatching, the young swans caring parents for about 9 months before the tail. Cygnets may return to their parents for longer trips into deeper water, but Black Swans undertake this behavior less frequently than Mute and Black-necked swans. Black Swan was a literary or artistic image, even before the opening of Cygnus atratus. Black Swan on the flag and the functions of both the state and bird emblem of Western Australia, it also appears in the coat of arms and other iconography of the state institutions.

Grey parrot

 

The Life of Animals | Grey parrot | Like many large parrots, the African Grey is a long life of birds. The Guinness Book of Records with a gray parrot who would have lived 72 years in captivity, as the longest lived of the sample species. In 2012 the species was vulnerable to further uplisted. Grey parrots depend on large old trees for the natural caves. Them to nest Studies in Guinea and Guinea-Bissau have found that African gray parrots preferred species of nesting trees are also preferred timber species. There is a positive relationship between the status of the species and the status of primary forests, where forests are declining, so the populations of gray parrots The African gray parrot is listed in Annex II to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).


With exports accounting for more than 350,000 copies from 1994 to 2003, the gray parrot is one of the fastest processed CITES-listed species of birds. This review has resulted in recommended zero export quotas for the states, and to develop a wider CITES decision to regional management plans for the species. In the United States, the importation of wild-caught gray parrots under the laws of the United States Wild Bird Conservation is prohibited 1992nd In the European Union, an EU Directive of 2007 prevents importation of this and other birds caught in the wild for the pet trade.


Unlike other parrots, wild African Greys have documented imitate the calls of several other species. The research of Dr. Irene Pepperberg with gray parrots in captivity, particularly with a bird named Alex, assign the scientific capability, simple human words with meanings and intelligently apply the abstract concepts of shape, color shown, number, zero-sense, etc. Many animals learn Congo African Greys, in their second or third year Timnehs usually speak to speak observed to start earlier. A study published in 2011, led by Dr. Dalila Bovet of Paris West University Nanterre La Défense, showed that African gray parrots could coordinate and cooperate with each other to an extent.


E 'was also observed, seemed to express that the parrots worked preferences over the birds of other tests. Whistle African Grey Parrots frequently, scream, squeal, click, etc. expect an African Grey owner should, regular deliveries of microwaves, phones, alarm clock, video games and other electronic sounds and water droplets to hear wild birds, and other sound you hear often from the parrot. African gray parrots have the ability to imitate, and between the different voices they hear to distinguish. Their sociability and intelligence can make African Grey Parrots excellent pets. They have a dedicated following among parrot owners. Greys require large cages, containing a varied diet of fresh foods, and plenty of safe and destructible toys. If they are not supplied with these elements Greys quickly develop unpleasant behaviors and can eventually develop health problems (such as feather plucking) which are difficult to eliminate. Even the healthiest, happiest pet African Grey will generate a fair amount of confusion and noise.

Crimson Rosella

 

The Life of Animals | Crimson Rosella | Platycercus elegans is a medium sized parrot Australian to 36 cm (14 in) in length, of which a wide tail part. The red is replaced by yellow var. flaveolus and a mixture of red, orange and yellow in the Adelaide Rosella. Young people are said to 'ripen' as they age and turn from green to red. All races have their cheeks blue and blue-black wings and tail-scalloped marginned predominantly blue with the color mainly red. The Crimson Rosella blue tail feathers are one of the favorite decorations of the satin bowerbird. There is very little sexual dimorphism in Crimson Rosella. The Crimson Rosella is located in the south-east of South Australia, through Tasmania, Victoria and New South Wales, on the south-east Queensland. A diverse population occurs in northern Queensland.


Lives mainly in forests and woodlands, preferring old forests and wetter. They are found in tropical rain forests, subtropical and temperate, wet and dry sclerophyll forests, riparian forests and woods, all the way from sea level to the tree line. Almost all Rosellas are sedentary, but from time to time people are considered nomads, not Rosellas are migratory. Outside the breeding season, Crimson Rosella tend to cluster in pairs or small groups and parties in power. The largest groups are mostly composed of young people who will gather in groups of up to 20 people. Crimson Rosella forage in trees, shrubs and ground for fruit, seeds, nectar, berries and nuts in a large variety of plants, including members of the family Myrtaceae, Asteraceae, and Rosaceae. Despite eating fruit and seeds, Rosellas are not useful for the spreaders seed plants, because crush and destroy the seeds in the process of eating.


Adelaide Rosella are known to feed on sleeping buds of cherry blossoms. Only a few will nest in a given tree. Some guard their nest perched near Rosellas to talk with others who are approaching. They will have a buffer zone of several trees radius also look around their nest, preventing other pairs of nests in that area. The breeding season of the Crimson Rosella lasts from September to February, and depends on rainfall each year starts earlier and lasts longer in wet years. Only the mother incubates the eggs. The eggs hatch in mid-December, with an average of 3.6 eggs hatching successfully. There is a preference for female chicks, as 41.8% of young people. The young reach adulthood (gain adult plumage) at 16 months. Opossum and currawongs are also believed to take from time to time the eggs from the nest. Surprisingly, but the Crimson Rosella is his worst enemy.

Magpie Goose

 

The Life of Animals | Magpie Goose | Magpie geese are unmistakable birds with their black and white plumage and yellow legs. T The males are larger than females. Related and existing families, Anhimidae (Schreier) and Anatidae (ducks, geese and swans), contain all other taxa. The Magpie Goose included in the genus and family Anseranas Anseranatidae the monotypic in our time A cladistic study determined the morphology of waterfowl that the Magpie Goose was an early and distinctive offshoot, according to various screamers and all other ducks, geese and swans. This family is pretty old, a living fossil, the set appeared before the Cretaceous-Tertiary extinction relative lived Vegavis IAAI ago 68-67000000 years.


Considered other Paleogene birds sometimes as magpie geese families of Geranopsis Hordwell formation are late Eocene to early Oligocene of England and Anserpica from the Late Oligocene of Billy Crechy (France). The earliest known member of the group is represented in Australia found an unnamed species of fossils in the late Oligocene Carl Creek Limestone of Queensland. The Australian distribution of the species is well adapted to the presumed Gondwana origin Anseriformes, but Northern Hemisphere fossils are enigmatic. Perhaps the magpie geese were one of the dominant groups Paleogene waterfowl, are largely extinct later. The Magpie Goose is found in a large number of open wetlands such as floodplains and swamps.


The area even as far south as the Coorong and the wetlands of south-east of South Australia and Western Victoria expanded. The species is the subject of reintroduction projects as Bool Lagoon between Penola and Naracoorte. In Victoria, the Magpie Goose listed as near threatened on the 2007 advisory list of threatened vertebrate animals in Victoria. In December 2007 the Flora and Fauna Guarantee Act list of threatened fauna, it is also called.
