Talk:White rhinoceros

Rhino species

Black, Northern White, Southern White, Javan, Great Indian and Sumatran. Tho Northern White and Javan there is very few left--Big5Hunter 12:15, 4 October 2007 (UTC)

Don't want to leave this unaddressed for anyone who might be reading. Northern and Southern White are subspecies. The only five at the species level are White, Black, Javan, Indian and Sumatran. --JayHenry 05:03, 31 October 2007 (UTC)

This article should be updated and merged to include both species Northern (Ceratotherium simum cottoni) and Southern (Ceratotherium simum simum). Also there is only 7 Northern know to be alive now (Early 2007 stat).--Big5Hunter 12:27, 4 October 2007 (UTC)

White Rhino Size

Why is there so little information about these animals size and weight? Because they havent got enough money to funf these experiments. Thw weight sounds bullshit. On average, this rhino weighs 2.2 tons. So, the theoretically maximum weight should be around 4 tons. 4.5 tons is completely unimaginable. Must be a hoax.

Anyway, white rhino is larger than hippo for sure. The hippo weight: 4500kg, is really an exaggeration.

Never seen more than 3,600 kg in scientific literature; some have had it as low as 2,300 kg, but this appears to be the average. Modern literature puts the hippo's maximum between 2,500–3,200 kg (some zoological journal gave 2,664 kg as the recorded maximum), with an average of 1,600 kg for males. 4,500 kg for either species is gross exaggeration – the Asian Elephant has a maximum of 5,400 kg in the wild and 6,198 kg in captivity. --Anshelm '77 (talk) 00:42, 31 March 2008 (UTC)

I find the comment, 'largest land MAMMAL after the elephants' (my emphasis) to be quite underwhelming. What other land animal would be bigger? Lukebulger (talk) 11:03, 31 March 2009 (UTC)

Additional Reference

There is a LOT of information on the northern white rhino in a journal article by Avant (2004) which I used in order to add a history section to the Garamba National Park Wikipedia article. The full reference is available on the Garamba page. Includes a great deal of information on the politics of the effort to save the rhinos, as well as detailed information on poaching in Garamba National Park. Definitely worth some additional gleaning, which I do not have time to do now. N2e 20:05, 26 October 2006 (UTC)

Introduction

The introduction talks about white rhino being the second biggest land animal. According to that the great one horn rhino (or whatever it's called) is actually larger. I am especially concerned about the introduction that sounds very similar to the one for great one horn rhino. Only one of them is the second largest land animal but I really do not know which one gets the honor so I will not fix it myself. Could some rhino expert look at that?

Indian Rhinoceros has about the same mass. Probably no way to distinguish which on average is larger. Rmhermen 15:09, 7 December 2006 (UTC)

Something

There is non-sense in the article "White Rhino" - Angalifu is NOT the last known male Northern White Rhino in existence. In Dvur Kralove live another two males (there were three there, as is written in wiki article "Northern White Rhino", but one of them died already). —Preceding unsigned comment added by 79.98.154.152 (talk) 08:50, 7 October 2008 (UTC)

Removed "A study has shown that they are very cool!!!" Don't think that should have been there. —The preceding unsigned comment was added by 83.141.119.180 (talk) 12:14, 4 April 2007 (UTC).

kira The name White Rhino originated in South Africa where the Afrikaans language developed from the Dutch language. The Afrikaans word "wyd" (derived from the Dutch word "wijd"), which means "wide", referred to the width of the Rhinoceros mouth. Early English settlers in South Africa misinterpreted the "wyd" for "white". So the rhino with the wide mouth ended up being called the White Rhino and the other one, with the narrow pointed mouth, was called the Black Rhinoceros. The wide mouth was adapted to cropping large swaths of grass, while the narrow mouth was adapted to eating leaves on bushes. A White Rhino's skin colour is quite similar to that of the Black Rhino. An alternative common name for the white rhinoceros, more accurate but rarely used, is the square-lipped rhinoceros. The White Rhinoceros' genus, Ceratotherium, appropriately means "horned beast". The White Rhinoceros' epithet, simum, is from the Greek simus, meaning "flat nosed" Simum also means a sand storm.

[edit] Physical description The White Rhino has a massive body and large head, a short neck and broad chest. The average size range of a mature rhino is a weight of 1800-3000 kg (4000-6600 lb), a head-and-body length of 3.35-4.2 m (11-13.9 feet) and a shoulder height of 150-185 cm (60-73 inches). The record-sized White Rhinoceros was about 3600 kg. On its snout it has two horns made of keratin, rather than bone as in deer antlers. The front horn is larger that the other horn and averages 89.9 cm (23.6 inches) in length and can reach 150 cm (59 inches). The White Rhinoceros also has a noticeable hump on the back of its neck which supports its large head. Each of the rhino's four stumpy feet has three toes. The colour of this animal ranges from yellowish brown to slate grey. The only hair on them is on the ear fringes and tail bristles. White Rhinos have the distinctive flat broad mouth which is used for grazing.

Did you mean 59.9 cm? 23.6 in is not 89.9 cm (=35.4 in). --Anshelm '77 20:48, 21 May 2007 (UTC)

Its ears can move independently to pick up more sounds but it depends most of all on smell. The olfactory passages which are responsible for smell are larger than their entire brain.

[edit] Behaviour and ecology They are found in grassland and savannah habitat. Herbivores grazers that eats grass, preferring the shortest grains. The White Rhino is one of the largest pure grazers. Regularly it drinks twice a day if water is available, but if conditions get dry it can live four or five days without water. It spends about half of the day eating, one third resting and the rest of the day doing various other things. White Rhinos like all species of rhino love wallowing in mudholes to cool down.

White Rhinos enjoying a wallow in the mud.White rhinos can produce sounds which include a panting contact call, grunts and snorts during courtship, squeals of distress, and deep bellows or growls when threatened. Threat displays (in males mostly) include wiping its horn on the ground and a head-low posture with ears back, combined with snarl threats and shrieking if attacked. Can reach speeds of 18 mph which it can maintain for up to 2 miles, and a galloping speed of 25 mph.

White Rhinos can live in groups of up to 14 animals (usually mostly female). Sub-adult males will congregate, often in association with an adult female. Most adult bulls are solitary. Dominant bulls mark their territory with excrement and urine. The dung is laid in well defined piles. It may have 20-30 of these piles to alert passing rhinos that it's his territory. Another way of marking their territory is wiping his horns on bushes or the ground and scrapes with its feet before urine spraying. They do this around 10 times an hour while patrolling territory. The same ritual as urine marking except without spraying is also commonly used. The territorial male will scrape-mark every 30 yards or so around its territory boundary. Subordinate males do not mark territory. The most serious fights break out over mating rights over a female. Female territory is overlapped extensively and they do not defend it.

[edit] Reproduction Females reach sexually maturity 4-5 years while males reach sexual maturity at a later date which is 10-12 years of age. Courtship is often a difficult affair. The male stays beyond the point were the female acts aggressively and will give out a call when approaching her. The male chases and or blocks the way of the female while squealing or loud-wailing if the female tries to leave his territory. When ready to mate the female curls its tail and gets into a stiff stance during the half hour copulation. Breeding pairs stay together between 5-20 days before they part their separate ways. Gestation occurs around 16-18 months. A single calf is born and weighs between 88 and 143 pounds and are unsteady for their first 2 to 3 days of life. When threatened the baby will run in front of the mother. The mother is very protective of her calf and will fight for her baby vigorously. Weaning starts at 2 months and may continue suckling for over 12 months. The birth interval for the White Rhino is between 2 and 3 years. Before giving birth the mother will chase off her current calf. White Rhinos can live up to 40-50 years old.

[edit] Population and threats The northern subspecies is now only found in the Democratic Republic of Congo while the southern subspecies or majority of white rhino live in South Africa. 98.9% of white rhino occur in just four countries (South Africa, Namibia, Zimbabwe and Kenya). Almost decimated to the brink of extinction in the early 20th century, they have made a tremendous comeback. In 2001 it was estimated that there was 11,670 white rhino in the wild with a further 777 in captivity worldwide, making it the most common Rhino in the world.

Like the Black Rhino, the White Rhino is under threat from habitat loss and poaching, most recently by an offshoot of the janjaweed. The horn is mostly used for traditional medicine although there are no health benefits from the horn. Poaching also has occurred for jambiyas, which is a dagger used in the Middle East. A recent population count in the Congo turned up only 10 rhinos left in the wild, which led conservationists in January 2005 to propose airlifting White Rhinos from Garamba into Kenya. Although official approval was initially obtained, resentment of foreign interference within the Congo has prevented the airlift from happening as of the beginning of 2006.

Proposed merge

I'd like to propose merging the articles Southern White Rhinoceros and Northern White Rhinoceros into the article White Rhinoceros. My reason is pretty straightforward—if we keep these as three separate articles there will be tremendous overlap in their content. The Northern and Southern White rhinoceroses are subspecies of the White Rhinoceros, as such, the majority of information about one applies to the other. Eventually, it would be great to get White Rhinoceros to featured article status, and merging this information would be a good start. I want to be very clear: my goal with this proposal is to remove absolutely no information whatsoever. The complete contents of each subspecies article will be included at White Rhinoceros. My goal is only to reduce redundant content. As best I can tell, all Featured Articles about animals are written at the species level, with subsections on subspecies. This seems to me like a good standard to pursue. --JayHenry 17:08, 5 September 2007 (UTC)

• Support merge...sort of. I'm sure much material is identical and for the most part species are taken as a fairly index point to have a comprehensive article. You could start by just restructuring and importing material anyway without officially merging.cheers, Casliber (talk · contribs) 04:38, 6 September 2007 (UTC)

• Support again sort of, the northern white rhino and southern white rhino articles should be merged because diet, behavior, ecology, ect. will all overlap. Conservation of the Northern White Rhino however is a significant issue and deserves to be maintained as a separate article. SeanBBSc 04:37, 21 September 2007 (UTC) Sean

  I would like to deal with conservation of the northern white rhino, in great detail, in this article. Because the northern white is so rare the vast majority of science on the subspecies is conservation related anyways and that can all be included here. --JayHenry 04:53, 31 October 2007 (UTC)

• Two subspecies of White Rhino should be merged into one article. As most people dont even know their is two sub species. They are closely related so alot is the smae but it would also make comparison of differences easier--Big5Hunter 11:58, 4 October 2007 (UTC)

merge update

I went ahead and merged Southern White Rhinoceros. As the type subspecies it'd really be fully redundant. I think Sean makes an interesting point about conservation of Northern Whites. I'm willing to leave that for now as I haven't done the research yet to say how much there is. Been focusing on Javan Rhinoceros for now... --JayHenry 04:59, 31 October 2007 (UTC)

Since they have been merged black and white rhino pages should be deleted as they are redundant.--203.192.91.4 (talk) 09:25, 19 November 2007 (UTC)

Northern White Rhino

While Wikipedians may decide to merge the Northern and Southern White Rhino articles into a single page, it is critical to note that there are distinct conservation efforts directed towards both. It is quite misleading to the casual observer to see that the northern white rhino is not clearly listed as critically endangered in the right-hand panel. By all accounts, there are no more than 20 alive! I searched for "Northern White Rhino" after reading "Last Chance to See" by Douglas Adams, and was surprised to learn that there was not a distinct page dedicated to this animal. Due to the extremity of the situation I believe the northern white rhino deserves a substantially clear amount of explanation. Furthermore, the only reference on wikipedia quoting the number of northern white rhinos currently alive is a BBC webpage. It is very likely that page contains outdated information. —Preceding unsigned comment added by Ian7208 (talk • contribs) 08:53, 25 January 2008 (UTC)

Contradiction

I added the contradiction-tag to the "In Zoos" section because it contradicts what is written in the Northern White Rhinoceros article. According to this article, the population in San Diego IS breeding and the male there is NOT the only one in existence. In addition, I removed info about Southern White Rinos in captivity; considering there are a total of more than 750, I don't see why the ones mentioned are notable. Preslav (talk) 15:05, 27 June 2009 (UTC)

Another Contradiction

As of August 14, 2010, both the White Rhinoceros and the Indian Rhinoceros are listed as being the largest rhinoceros on their respective pages. Thegoldenconciseencyclopediaofmammals (talk) 20:29, 14 August 2010 (UTC)

no disambiguation page?

This isn't what most people mean when they say white rhino
