Macaws New World Parrots

Macaws Long Tailed Colorful Parrots



Macaw is a kind of parrots often called New World Parrots. There are many different types of these parrots. These parrots are native to Central America, South America and Caribbean. Most of the Species are associated with Rainforests and Woodland. Larger beaks and long tails are the main characteristics of these kindda parrots.

Macaw Species



The largest macaws are the Hyacinth and the smallest member of the family is the red shouldered Macaw. It is no larger than some parakeets of the genus Aratinga. There are nineteen species of Macaws and several hypothetical extinct species that have been proposed based on very little evidence. Some of species names are follows: Glaucous Macaw, Hyacinth Macaw, Lear's Macaw, Spix's Macaw, Blue and Yellow Macaw etc...

Macaws Hybrids and Foods



Macaws are also hybridized for the purpose of pet trade. Hybrids are typical macaws with the only difference from true species being their genetics and their colors. These birds eats variety of foods including seeds, nuts, fruits, leaves and flowers etc.

Gentoo Penguin

The long-tailed Gentoo penguin is a penguin species in the genus Pygoscelis, most closely associated with the Adélie penguin (P. adeliae) and the Chinstrap penguin (P. antarcticus). The first scientific description was made in 1781 by Johann Reinhold Forster on the basis of Falkland Islands. They call in a variety of ways, but the most frequently heard is a loud trumpeting which is emitted with its head thrown back. The application of Gentoo to the penguin is unclear.
 
 
The Oxford English Dictionary notes that Gentoo used to be an Anglo-Indian term used as early as 1638 to distinguish Hindus in India from Muslims. The English term originated from the Portuguese gentio (compare "gentile"); in the 20th century the term came to be regarded as derogatory. The Gentoo penguin is one of three species in the genus Pygoscelis. Mitochondrial and nuclear DNA evidence suggests the genus split from other penguins around 38 million years ago, about 2 million years after the ancestors of the genus Aptenodytes.
 
 
In turn, the Adelie Penguins split off from the other members of the genus around 19 million years ago, and the Chinstrap and Gentoo finally diverging around 14 million years ago. The gentoo penguin is easily recognized by the wide white stripe extending like a bonnet across the top of its head and its bright orange-red bill. They have pale whitish-pink webbed feet and a fairly long tail the most prominent tail of all penguins. Chicks have grey backs with white fronts. As the Gentoo penguin waddles along on land, its tail sticks out behind, sweeping from side to side, hence the scientific name Pygoscelis, which means "rump-tailed".
 

Gentoos reach a height of 51 to 90 cm (20 to 35 in), making them the third largest species of penguin after the two giant species, the Emperor Penguin and the King Penguin. Males have a maximum weight of about 8.5 kg (19 lb) just before molting, and a minimum weight of about 4.9 kg (11 lb) just before mating. For females the maximum weight is 8.2 kg (18 lb) just before molting, but their weight drops to as little as 4.5 kg (9.9 lb) when guarding the chicks in the nest. Birds from the north are on average 700 g (1.5 lb) heavier and 10 cm (3.9 in) taller than the southern birds.
 

Southern Gentoo penguins reach 75-80 cm (30-31 in) in length. They are the fastest underwater swimming penguins, reaching speeds of 36 km/h (22 mph). Gentoos are adapted to very harsh cold climates. The breeding colonies of gentoo penguins are located on ice-free surface. Colonies can be directly dependent on the shoreline but are also considerably located inland. They prefer shallow coastal areas and often nest between tufts of grass. In South Georgia, for example, breeding colonies are two kilometres inland.

Tundra Swan

Tundra Swan is the smallest of the Holarctic swans, a 115-150 cm (45-59 inches) long, 168-211 cm (66-83 inch) wingspan and weighing 3.4 to 9.6 kg (7.5 to 21 pounds ). In adult birds, the plumage of both subspecies is completely white, with black legs, and a bill that is mostly black, pink salmon with a thin strip along the line of the mouth and depending on the subspecies more or less yellow in the proximal part. In birds in water containing large amounts of iron ions (bog lakes), head and neck feathers contains acquires a golden hue or oxidized. Downy young are silvery gray above and white below.


Swans small subspecies are smaller. There is a size slightly lean with eastern birds are slightly larger, the data is only good for the West, however. These roads 3,4-7.8 kg (7.5 to 17 pounds) 6.4 kg (14 lbs) on average for men and 5.7 kg (13 pounds) in women. Measuring tarsus 9.2 to 11.6 cm (3.6 to 4.6 inches) in length, the account of 8.2 to 10.2 cm (3.2 to 4.0 inches), with an average of 9 , 1 cm (3.6 inches). Little Swan is similar in appearance to the noblest Whooper Swan (Cygnus C.) but the neck is smaller, shorter and has a more rounded head, with the standard variable account, but always as black and a yellow patch base yellow upturned nose.


Wild Swans have an account that has more yellow than black and the tip of the yellow stain is usually addressed. The Little Swan invoice template for each individual is unique, and scientists often detailed drawings of each invoice and assign names to the swans to help in the study of these birds. A clear case of hybridization between a small and a vagrant Whistling Swan was reported in eastern Siberia.


Whistling swans weigh 9.5 to 21 pounds (4.3 to 9.5 kg) - 16 pounds (7.3 kg) on average for men and 14 pounds (6.4 kg) in women - and measuring 47 -59 cm (120-150 cm) long. It differs from allopatric great trumpeter Swan (C. buccinator) of North America, far greater than the size and type of black beak particularly long, is everywhere except mouth pink line, which is stronger than in Whistling Swan.Tundra Swans have some calls and shrill sounds like a goose honking black (Branta).


The casting call that is called low and smooth bark, Bow-Wow Whistling Swan gives a loud bark as clear trisyllabic wow-wow-wow in flight. Moreover, the Wild Swans trumpeter and names accurately describe your calls - a deep hoot hoot and a larger horn tone, respectively. Begin to reach spawning in mid-May, and leave for winter quarters in late September. Some birds also winter elsewhere on the south coast of the North Sea. Swans small breeds in eastern Russia migrate via Mongolia and northern China in winter in coastal areas of Korea, Japan and southern China, Guangdong, south and sometimes even Taiwan.

King Vulture

The King Vulture is the largest of the New World vultures. A majestic king vultures bird adult plumage is mainly white, with a touch of pink and yellow for him. By contrast, wing coverts, flight feathers and tail are dark gray to black, and the first floor of the flange thickness. The head and neck are free of feathers, skin tones of red and purple on the head, neck and throat bright yellow orange. King Vulture has the largest skull and skull into account and New World vultures.

King Vulture Credit

The bird has broad wings and short tail, broad and square. Unlike some missing eyelashes king vulture. The vulture is little sexual dimorphism, with no differences in plumage and a little in size between males and females. The young vulture beak and dark eyes and a soft, gray neck, orange before becoming an adult. Young vultures are a slate gray complex, although similar in appearance to adults.
 

The last stages immature black feathers on the wings scattered white blankets otherwise their children. The head and neck are vulture feathers as an adaptation for hygiene, good black hair on the sides of the head, this lack of feathers prevents bacteria feed the springs of the channel and causes skin damage from sterilizing effects of Sun Dark plumage immature birds may be confused with C. aura, but flies with wings of feathers smooth, pale, while adults are quite realistic confused with the stork, but outside of its long neck and legs allow easy recognition

King Vulture Credit

King Vulture live about 14 million km2 (5.4 million MI2) between southern Mexico and northern Argentina. In South America, living in the western Andes, except in the western part of Ecuador, Colombia to the northwest and northwest Venezuela. Lives mostly intact lowland tropical forests and savannas and grasslands with these forests nearby.


This bird is often the most numerous vulture or primary lowland forests in its range, but the Amazon is the great Head of Eagle outnumbered usually yellow, while usually outnumbered by the Lesser Yellow header, Turkey Vulture and open environments. King Vulture effortless flight hours, and often exceeds their wings. During the flight, the wings are flat with slightly raised tips by far the vulture flight may appear headless.

Great Blue Heron

It is the largest North American heron herons and among all existing, surpassed only by the Goliath heron and white-bellied heron. Head-to-tail length of 91-137 cm (36-54 inches), with a magnitude of 167-201 cm (66-79 inches), a height of 115-138 cm (45-54 inches) and a weight 2, 1 to 3.6 kg (4.6 to 7.9 pounds). Notable features include slate flight feathers, red-brown, red-brown thighs, and a band of black couple and sides, the neck is rusty gray, with black and white stripes on the front, the head is almost white pale face, and a pair of black feathers vary from just above the eye to the back of the head.
 
Great Blue Heron Credit
 
Immature birds are duller in color, with a dull blackish-gray crown, and the pattern of side weakly defined, without feathers, and the bill is dull gray-yellow. Heron step is about 22 cm (9 inches), almost straight. The subspecies differ only slightly in size and plumage tone, with the exception of subspecies occidentalis, which as normal colored birds, also has a separate white phase, known as the Grand White Heron (not to be confused with the Great Egret, for "Great White Heron" was once a common name).
 

Intermediate between Birds normal and white morph morph are known as Heron Wurdemann, these birds look like a blue "normal" Excellent bald. The Great Blue Heron is found throughout most of North America, as far north as Alaska and the southern provinces of Canada. The range extends south through Florida, Mexico and the Caribbean South America. Birds east of the Rocky Mountains in the northern part of their range are migratory and winter in northern Central America and South America.
 

The Great Blue Heron can be adapted to almost any wetland habitat in its range. Great Blue Heron rarely venture away from streams, but sometimes seen flying over mountainous areas. This species usually breeds in colonies in trees close to lakes or other wetlands. Often, these colonies are only great blue herons, sometimes with other species of herons nest. These groups are called colonies (a more precise term "colony").
 

The size of these colonies can be large, between 5-500 nests per colony, with an average of approximately 160 nests per colony. Great Blue Herons build a bulky stick nest, and the female lays 3-6 eggs blue. Repeated human intrusion into nesting areas often results in nest failure, with abandonment of eggs or chicks. Both parents feed the young in the nest by regurgitating food. Predators of eggs and chicks are vultures, hawks and crows, raccoons, bears different, the latter two also potential predators of adults.

Atlantic Puffin

The Atlantic Puffin is 26-29 cm (10-11 inches) in length (cm Bill 3-4) with a 47-63 cm (19-25 in) wingspan. This bird is mainly black above and white below, with gray to white cheeks and red-orange legs. Features bright Orange bill plates grow before the breeding season and autumn, after the reading. The Horned Puffin on (Fratercula corniculata) from the North Pacific is very similar, but slightly different head ornaments.
 
Atlantic Puffin Credit

The Atlantic Puffin is typically silent at sea, except for soft purring sounds it sometimes makes in flight. In breeding colonies, it is the most common call is a trisyllabic KAA-AAR-aar, while birds make a short growl when startled. This species breeds on the coasts of northern Europe, the Faroe Islands, Iceland and North America, the Arctic Circle to northern France and Maine.
 


Approximately 95% of puffins in North America breed around the coast of Newfoundland. The largest puffin colony in the western Atlantic (estimated at more than 260,000 pairs) can be found at the Witless Bay Ecological Reserve, south of St. John's, Newfoundland and Labrador. Puffin viewing has also started to become popular in Elliston Newfoundland, previously named Bird Island Cove, located near Trinity.


Predators Puffin include the Great Black-backed Gull (Larus marinus), the Great Skua (Stercorarius skua), and species of similar size, which can take a puffin in flight, or choose from a separate colony. Smaller species, such as gulls Herring Gull (L. argentatus) which are hardly able to get a healthy adult puffin, take eggs or newly hatched chicks, and even flying fish.


Species may face competition from other animals nesting burrows, such as rabbits, Manx shearwaters and sometimes penguin. The only time spent on land is nest colleagues before arriving in the colonies, and in the sea coupling. The breeding season is normally puffins in the summer, eggs are laid in June and July. Synchronous spawning is in Puffins in adjacent burrows. In the Faroe Islands, for example, birds may be hunted for local consumption after the breeding season, when excess birds available.

Canada Goose

The head and neck black, with a "chinstrap" distinguish the Canada goose from all the other white geese, with the exception of the Barnacle Goose, but the second has a breast black and gray, rather than the body brown plumage. There are seven subspecies of this bird, in different sizes and plumage details, but all recognized as Canada geese. Some of the smaller breeds can be difficult to distinguish from the crowd noise small overlap Goose.
 
 Canada Goose Credit

However goose chatting generally much smaller, a little 'bigger than Mallard, with a shorter neck and smaller bill. The largest is the subspecies B. c. Maxima or "Giant Canada Goose," and smaller (in common with the group cackling goose) is B. c. parvipes or "lesser Canada goose This specimen is the largest wild goose ever recorded of any kind. Life expectancy in the wild of geese that survive to adulthood including 10-24 years.


Like most geese, the Canada Goose migratory course. The wintering area in the United States more calls head from large groups of Canada Geese in V formation of signal transitions in the spring and autumn. In some areas, migration routes have changed due to changes in habitat and food sources. In the second year of their life in Canada Geese find a mate. The female lays 3-8 eggs and both parents protect the nest while the eggs incubate, but the female spends more time in the nest than the male. The egg predators are known to Arctic foxes coyotes, raccoons, foxes from the north, large gulls, Raven, crows and bears Americans.
 
 
As changes occur during the annual summer breeding season, adults lose their flight feathers on the day 20-40, recovered flight around the same time as you start flying geese The geese are often seen leading goose online, usually a parent in front and one on the back. Although parents are hostile foreign geese may form groups of a number of geese and a few adults, called crèches.
 

In North America, non-migratory Canada goose populations have increased. The species is often found on golf courses, parking lots and parks, the only migratory geese on rare occasions, however. In many areas, non-migratory Canada Geese are now considered pests by humans. It The agency responds to municipalities or private landowners, such as golf courses, the geese obtrusive or object to their waste. Nests Addling goose eggs are destroyed and as a method of birth control for people promoted Geese have a tendency to attack humans when they feel threatened themselves or their goslings.

Quetzal

Quetzals are strikingly colored birds in the trogon family. They are found in forests and woodlands, especially in humid highlands, with the five species from the genus Pharomachrus being exclusively Neotropical, while the single Euptilotis species is almost entirely restricted to western Mexico also in Baja Verapaz, Guatemala.

Quetzal Credit

They are fairly large (all over 32 cm or 13 inches long), slightly bigger than other trogon species. Quetzals have iridescent green or golden-green wing coverts, back, chest and head, with a red belly. They are strongly sexually dimorphic, and parts of the females' plumage are brown or grey. These largely solitary birds feed on fruits, berries, insects and small vertebrates (such as frogs).

 Quetzal Credit

Even with their famous bright plumage, they can be hard to see in their natural wooded habitats. None of the quetzal species are under immediate threat in the wild, although the Resplendent Quetzal is at Near Threatened status. The name "quetzal" is from Nahuatl quetzalli  "large brilliant tail feather" (American Audubon Dictionary) or "tail coverts of the quetzal" (Merriam-Webster's Collegiate Dictionary), from the Nahuatl root quetz = "stand up" used to refer to an upstanding plume of feathers.

Quetzal Credit

The word "quetzal" was originally used for just the Resplendent Quetzal, the famous long-tailed quetzal of southern Mexico and Central America, which is the national bird and the name of the currency of Guatemala. It still often refers to that bird specifically but now also names all the species of the genera Pharomachrus and Euptilotis.

Quetzal Credit

Pharomachrus is from Ancient Greek pharos, "mantle", and makros, "long", referring to the wing and tail coverts of the Resplendent Quetzal (the second h is unexplained). Euptilotis neoxenus is related to Pharomachrus and is called the Eared Quetzal by some authorities, such as the American Ornithologists' Union, but the Eared Trogon by others.

Whooping Crane

The Whooping Crane (Grus americana) the tallest North American bird, is an endangered crane species named for its whooping sound. An adult whooping crane is white with a red crown and a long beak dark bill. Immature whooping cranes are cinnamon brown. Adult whooping cranes wing bullets "are visible in flight. Males weigh on average 7.3 kg (16 lb), while females weigh 6.2 kg (14 lbs) average (Erickson, 1976). standard linear measures cranes have a length Rope 53-63 cm (21-25 inches), a length of 11.7 to 16 culmen exposed cm (4.6 to 6.3 inches) and the tarsus 26-31 cm (10 -12).


The only other large, long-legged white birds in North America: the great egret, which is just a short walk and a seventh of the weight of the crane, the white heron, which is a metamorphosis of the heron Great Blue in Florida, wood storks and herons. The first call to choir nature ever taken in the wintering Whooping Crane "in the Aransas National Wildlife Refuge in December 1999 and is documented here

Whooping Crane Credit

The muskeg of the taiga in Wood Buffalo National Park, Alberta, Canada, and the area was the last vestige of the old breeding habitat of the Whooping Crane Summer range. However, with the recent reintroduction cry Crane Eastern Partnership Project, whooping cranes nested naturally for the first time in 100 years of Necedah National Wildlife Refuge in central Wisconsin, USA. Usually, no more than a young bird survives in a season. Salt Plains National Wildlife Refuge in Oklahoma is an important milestone for the crane population traveling more than 75% of annual species is maintained.

Whooping Crane Credit
 
In 1941, the wild population consisted of 21 birds. Pertussis crane remains one of the rarest birds in North America. The U.S. Fish and Wildlife Service has confirmed that 266 whooping cranes migration to Aransas National Wildlife Refuge in 2007. Among the many potential predators and nest breeding American Black Bear (Ursus americanus), Wolverine (Gulo gulo), Gray Wolf (Canis lupus), Red Fox (Vulpes vulpes), Lynx (Lynx canadensis), Bald Eagle (Haliaeetus leucocephalus) and the raven (Corvus Corax). Golden eagles died young whooping cranes and fledgings.

Whooping Crane Credit

The lynx has killed many whooping cranes in Florida and Texas In Florida, lynx are the cause of most deaths of whooping cranes, including many adults and documented for the first chick born in the wild in 60 years. At least 12 lynx were captured and moved in an attempt to save the cranes. American alligators have a pair of whooping cranes in Florida. Food Potential breeding birds in the summer include frogs, small rodents, small birds, fish, aquatic insects, crabs, mussels, snails, potatoes, berries and water.

Ostrich

Ostriches usually weigh 63-145 kg (140-320 kg), East African Ostrich Race (S. c. Massaicus) with an average of 115 kg (250 lb) for males and 100 kg (220 lb) in women, and the name subspecies is pounds (240) on an average of 111 kg in adults unsexed. Exceptional male ostriches (nominal subspecies) weigh up to 156.8 kg (346 lb). When they reach sexual maturity (2-4 years), male Ostriches can be from 2.1 to 2.8 m (6 feet 11 inches to 9 ft 2 in) to be in height, while female Ostriches range from 1.7 to 2 m (5 ft 7.6 ft 7 in) tall.

Ostrich Credit

New girls are yellow-brown, with dark brown spots. Age, ostriches weigh around 45 kg (99 lbs). The feathers of adult males are mostly black, with white primaries and a white tail. Women and young men are gray-brown and white. The head and neck of both male and female ostriches is almost naked, with a thin layer below. The skin of the neck and thighs is pinkish gray females, while the male is blue-gray, gray or pink, depending on subspecies.


The legs of the Ostrich are unfeathered and show bare skin, with the tarsus (the lowest part of the straight leg) is covered with scales: red to black women. The hock ostrich is the largest of all birds, measuring 39-53 cm (15-21 inches) in length. The bird has only two fingers for each foot (most birds have four). Ostriches can be run at a speed of over 70 km / h (43 mph) and able to cover 3-5 m (9.8 to 16 feet) in a single step. The wings are used in mating displays and chicks shadow.

The feathers lack the tiny hooks that bind together the smooth external feathers of flying birds, and so are soft and fluffy and serve as insulation. It can tolerate a wide range of temperatures ostriches. Ostrich sternum is flat, lacking the keel to the wing to bring the muscles, birds in flight. Like all ratites, the Ostrich has no crop, and it also lacks a gallbladder. Unlike all the birds, the Ostrich secretes urine separately from faeces. All the other birds Store urine and feces were combined in coprodeum, but the shops chair ostrich in the rectum terminal.
 

Unlike most birds, with males. The first fossil ostrich-like birds is the Palaeotis live close to the Asian steppes, from the Middle Eocene, a ratite size initially believed to be a bustard. While the relationship between the African species is relatively simple, a large number of Asian species of ostrich from fragmentary remains, and their relations are described and their relationship with the African ostriches is confusing.

Macaw

Macaws are long-tailed, often colourful New World parrots. Of the many different Psittacidae (true parrots) genera, six are classified as macaws: Ara, Anodorhynchus, Cyanopsitta, Primolius, Orthopsittaca, and Diopsittaca. Previously, the members of the genus Primolius were placed in Propyrrhura, but the former is correct in accordance with ICZN rules. Macaws are native to Central America (especially Mexico), South America, and formerly the Caribbean.


Most species are associated with forests, especially rainforests, but others prefer woodland or savannah-like habitats. Proportionately larger beaks, long tails, and relatively bare, light-coloured, medial (facial patch) areas distinguish macaws. Sometimes the facial patch is smaller in some species, and limited to a yellow patch around the eyes and a second patch near the base of the beak in the members of the genus Anodorhynchus. A macaw's facial feather pattern is as unique as a fingerprint.

Macaw Credit

The largest macaws are the Hyacinth, Buffon's (Great Green) and Green-Winged Macaws. While still relatively large, macaws of the genera Cyanopsitta, Orthopsittaca and Primolius are significantly smaller than the members of Anodorhynchus and Ara. The smallest member of the family, the Red-shouldered Macaw, is no larger than some parakeets of the genus Aratinga. Macaws, like other parrots, toucans and woodpeckers, are zygodactyl, having their first and fourth toes pointing backward.


The majority of macaws are now endangered in the wild and a few are extinct. The Spix's Macaw is now probably extinct in the wild. The Glaucous Macaw is also probably extinct, with only two reliable records of sightings in the 20th century. The greatest problems threatening the macaw population are the rapid rate of deforestation and the illegal trapping for the bird trade.

Macaw Credit

Macaws eat a variety of foods including seeds, nuts, fruits, palm fruits, leaves, flowers, and stems. Wild species may forage widely, over 100 km (62 mi) for some of the larger species such as Ara araurana (blue & yellow macaw) and Ara ambigua (great green macaw), in search of seasonally available foods. Some foods eaten by macaws in certain regions in the wild are said to contain toxic or caustic substances which they are able to digest.

Albatross

Albatrosses of the biological family Diomedeidae, are large seabirds allied to the procellariids, storm petrels and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains show they once occurred there too and occasional vagrants are found.


Albatrosses are among the largest of flying birds, and the great albatrosses (genus Diomedea) have the largest wingspans of any extant birds, reaching up to 12 feet (3.7 m). The albatrosses are usually regarded as falling into four genera, but there is disagreement over the number of species. Albatrosses are highly efficient in the air, using dynamic soaring and slope soaring to cover great distances with little exertion.


They feed on squid, fish and krill by either scavenging, surface seizing or diving. Albatrosses are colonial, nesting for the most part on remote oceanic islands, often with several species nesting together. Pair bonds between males and females form over several years, with the use of 'ritualised dances', and will last for the life of the pair. A breeding season can take over a year from laying to fledging, with a single egg laid in each breeding attempt.

Albatros Credit

The albatrosses comprise between 13 and 24 species (the number of species is still a matter of some debate, 21 being the most commonly accepted number) in four genera. These genera are the great albatrosses (Diomedea), the mollymawks (Thalassarche), the North Pacific albatrosses (Phoebastria), and the sooty albatrosses or sooties (Phoebetria). The North Pacific albatrosses are considered to be a sister taxon to the great albatrosses, while the sooty albatrosses are considered closer to the mollymawks.

Albatross Credit

The taxonomy of the albatross group has been a source of a great deal of debate. The Sibley-Ahlquist taxonomy places seabirds, birds of prey and many others in a greatly enlarged order, Ciconiiformes, whereas the ornithological organisations in North America, Europe, South Africa, Australia, and New Zealand retain the more traditional order Procellariiformes.

Greater Rhea

The Greater Rhea (Rhea americana) is a flightless bird found in eastern South America. Other names for the Greater Rhea include the Grey, Common, American Rhea, ñandú (Guaraní) or ema (Portuguese). One of two species in the genus Rhea, in the family Rheidae, the Greater Rhea is endemic to Argentina, Bolivia, Brazil, Paraguay and Uruguay. It inhabits a variety of open areas, such as grasslands, savanna or grassy wetlands. Weighing 50-55 pounds (23-25 kg), the Greater Rhea is the largest bird in South America.


Usually the males darker than females. Cub Rhea great with dark gray stripes. Nandu is endemic in Argentina, Bolivia, Brazil, Paraguay and Uruguay. A small population Rhea installed in Germany. At the end of 2000, the population is estimated in seven birds, and in 2001 eighteen birds. Nandu diet consists mainly of deciduous trees, fruits and seeds, especially when the season, but also insects, scorpions, small rodents, reptiles, birds and small. Meals include plants native species and introduced all kinds of bipartite families Amaranthaceae, Asteraceae, Bignoniaceae, cruciferous vegetables, legumes, Labiatae, myrtle, or nightshade family.


Accepted eat cereal or monocots in general. Even the vegetable materials such as hard and prickly thistle tubers or eat with pleasure. How many birds that feed on plant material, hard, grinders, which will help Nandu swallowing food for optimal digestion. It has attracted a lot of shiny objects, metal objects and sometimes ingested or bright. Young people consume more animal matter, than adults. Sometimes the fish will gather in rheas and eat carrion flies, but they are also known to eat dead or dying in the dry season, but not as commonly feed on vertebrates in large quantities.

Greater Rhiea Credit

If you have to set the time for the eggs, the male is usually already in the nest and act aggressive when approaching women. He's nest with wings gradually relax and allow you to bend over and put the egg on the edge of the nest. Male Roll the egg in the nest. The men are polygamous, women are serial polyandry. In practice, this means that women move during the breeding season, mating with the male, and the male before they lay eggs. Nests then shared between females can contain up to 80 eggs laid every ten women female coupling rooms about 5 to 10 eggs.


However, the average size of the coupling 26-7 eggs from different females. Recent studies have shown that some men use subordinate males to help protect and incubate the eggs. Rhea eggs the size of 130 mm × 90 mm (5.1 inches x 3.5 inches) and weighs 600 grams (21 ounces), the means of communication, so that they are half the size of an ostrich egg. The nest is a simple scrape flat and wide in a hidden place, men sticks, grass and leaves, in the immediate vicinity of the nest to attract a wide strip as similar to reach the neck. All the eggs hatch within 36 hours of each other, even if the eggs in the nest, may have only two weeks.
