Victoria crowned pigeon

 From - Earth Unreal & Wikipedia,

By - Vinuri Randula,


The Victoria crowned pigeon (Goura victoria) is a large, bluish-grey pigeon with elegant blue lace-like crests, maroon breast and red irises. It is part of a genus (Goura) of four unique, very large, ground-dwelling pigeons native to the New Guinea region. The bird may be easily recognized by the unique white tips on its crests and by its deep 'whooping' sounds made while calling. Its name commemorates the British monarch Queen Victoria.

The Victoria crowned pigeon is a deep blue-grey color with a small, black mask. Its feather crest (the signature feature of crowned pigeons other than their size) is conspicuously white-tipped. On the wing coverts is a row of feathers that are a paler blue-gray with maroon tips. These form a distinct wing bar. The chest is a deep purple-maroon color. As in all crowned pigeons, melanism has been observed. The other two crowned pigeons are somewhat superficially similar, but only the western crowned pigeon overlaps in range with the Victoria species.

This species is typically 73 to 75 cm (29 to 30 in) long. Some specimens may exceed a length of 80 cm (31 in) and a weight of 3.5 kg (7.7 lb). It is marginally larger than the two other crowned pigeons on average, at an mean of 2.39 kg (5.3 lb ) in adult body mass, thus is considered the largest surviving species of pigeon of Earth. The standard measurements among pigeons on mainland New Guinea are: the wing chord is 36–39 cm (14–15 in), the tail is 27–30.1 cm (10.6–11.9 in), the bill is 3.2–3.5 cm (1.3–1.4 in) and the unfeathered tarsus is 8.5–9.8 cm (3.3–3.9 in).

Like other crowned pigeons, this species makes a loud clapping sound when it takes flight. The mating calls of this species are also similar to the other two species of crowned pigeons, consisting of a deep hoota-hoota-hoota-hoota-hoota sound. When defending their territories, these birds make a resounding whup-up, whup-up, whup-up call. Their contact call is a deep, muffled, and rather human-like ummm or hmmm

Like other crowned pigeons, the Victoria crowned pigeon is a gregarious species. They usually travel in pairs or small parties as they search for food. They walk with an unhurried gait along the forest floor. Their food typically consists of fallen fruit. Birds of this species in captivity are particularly fond of eating figsSeeds and invertebrates may occasionally supplement the diet. When disturbed, these birds fly straight up into the canopy or a large horizontal branch of a large forest tree. After being disturbed, they may remain on their perch for a considerable time engaging in contact calls and flicking their tails. In the wild, this species tends to be shier than the western crowned pigeon, but can still occasionally be quietly approached. The males regularly engage in aggressive displays to establish dominance. In these interactions, the pigeons puff up their chests and repeatedly raise their wings as if preparing to strike their opponent. They also make short dashes at each other and may actually hit one another, but rarely make contact and can be completely peaceful towards other males outside of the early mating season.

Breeding peaks late in wet season and in the dry season. When the male displays for the female, he lowers his head down, stretches forward, and then rhythmically swings his head up and down while simultaneously wagging his fanned tail. Although the female does most direct brooding, both parents help raise the young. The female usually lays a single white egg in a well-built tree nest of stems, sticks, and palm leaves. In the weeks before she lays the egg, the male brings nesting material to the female. The egg is incubated around 30 days. The young leave the nest when they are still much smaller than their parents but are actively tended to for a total of 13 weeks.

The Victoria crowned pigeon is now the most rarely occurring of the three crowned pigeon species in the wild, although it is the most widely kept species in captivity. Perhaps the most pressing threat to the species is continuing habitat loss due to logging. It now quite uncommon near human habitations because it is heavily hunted around them, particularly in areas where gun possession is prevalent. It The Victoria crowned pigeon is evaluated as Near Threatened on the IUCN Red List of Threatened Species. It is listed in Appendix II of CITES.

Why did Homo sapiens outlast all other human species?

  From - Live Science By  Mindy Weisberger Edited by - Amal Udawatta Reproductions of skulls from a Neanderthal (left), Homo sapiens (middle) and Australopithecus afarensis (right)   (Image credit: WHPics, Paul Campbell, and Attie Gerber via Getty Images; collage by Marilyn Perkins) Modern humans ( Homo sapiens ) are the sole surviving representatives of the  human family tree , but we're the last sentence in an evolutionary story that began approximately 6 million years ago and spawned at least 18 species known collectively as hominins.  There were at least nine  Homo  species — including  H. sapiens  —  distributed around Africa, Europe and Asia by about 300,000 years ago, according to the Smithsonian's  National Museum of Nat ural History  in Washington, D.C. One by one, all except  H. sapiens  disappeared.  Neanderthals  and a  Homo  group known as the  Denisovans  lived alongside  H. sapiens  for thousands of years, and they even interbred, as evidenced by bits of their DN

Jared Leto climbs Empire State Building

The actor and musician has become the first person to legally scale the 102-story Empire State Building. Leto, 51, climbed the outside of the New York landmark in a bright orange jumpsuit and using a rope and harness. He took on the challenge to promote the forthcoming world tour for his band Thirty Seconds To Mars. Leto told NBC's Today show:  "I was more excited than nervous to tell you the truth. But I have to be honest, it was very, very hard. It was a lot harder than I thought it would be. "Just the endurance that it took, the stamina that it took, and it was very sharp."

Humans have been speaking for a lot longer than we originally thought

       From -  Independent Magazine      By - David Keys      Edited  by - Amal Udawatta New research has pinpointed the likely time in  prehistory  when humans first began to speak. Analysis by British archaeologist Steven Mithen suggests that early humans first developed rudimentary  language  around 1.6 million years ago – somewhere in eastern or southern Africa. “Humanity’s development of the ability to speak was without doubt the key which made much of subsequent human physical and cultural  evolution  possible. That’s why dating the emergence of the earliest forms of language is so important,” said Dr Mithen, professor of early prehistory at the University of Reading. Until recently, most human evolution experts thought that humans only started speaking around 200,000 years ago. Professor Mithen’s new research, published this month, suggests that rudimentary human language is at least eight times older. His analysis is based on a detailed study of all the available archaeological
