I have a passion for reading articles on Natural History & have read that in the regions where there are those exotic forests like Amazonia or Congo or in South East Asia you also have some quite large types of eagles specialised to catch big prey like sloths monkeys , Lemurs & even snakes :wacko: :huh: they also have the largest wing spans as well as over all sizes Akaar

Examples include the Harpy Eagle & the Phillipine eagle. Quite Large .

So if any of you are interested in the topic or know any thing about it then please share it with me & other members who are interested. Also if any of you come from such a place where you have such large Eagles or seen them up close or in documentaries so do tell us about the experience.

I have a large passion in natural history as well. I think a logical explanation is the fact that they live in areas with higher food densities and this allows them to grow to larger sizes. This happens amongst other species as well such as tigers. The largest tigers are found where there is the most prey, and room. However, the Steller's Sea Eagle which under the so-called Bergmann's Rule grows every bit as large.

Good & Great

Well actually you know what there is no hard & Fast rule governing the matter. In fact even in habitats which provide abundant sustenance you have species resorting to Dwarfish Size tendancies as well. Then again there have been times in History when Species of Various sizes have been coexisting & cohabbiting togeather. Like for instance a couple of years back in Indonesia there was a discovery of a cave in which you had Midjet Dwarf like Human ancesters living along side much larger races of Ancient Humans. I remember exactly the Dwarfs were named as Hobbit men.

Also in the Island of Bali you have the Smallest species of Tiger in the world.

And you know what that in places as far away as the Indonesian Islands & Sicly you have had elephants which at their full grown form could be lifted in the lap of a girl!!!

Better beleive it because it is true. There have also been dwarf Mammoths & Giant Kangaroos as well as Giant Lemurs etc.

Any ways I was wondering I had just opened a post in this subforum its self about Giant Lemurs , I think you better see that & post your vies as well.

Also such Giant Varieties of various life forms were found the world over untill some 12,000 ya i.e. around the end of the last Ice age. And actuallly uou cant blame humans for every thing that went wrong as human populations were quite low & it was not in our power at that time to wreack such a mass havoc & catastrophe simultaneously world wide. The Enviorenment was changing & thats a fact.

I know there is no clear cut rule. But, the Bali and Sumatran tigers live in areas with low prey densities, and they live on Islands as well. The largest tigers are where there is the most 'large' prey available. Same for the largest bears, and lions (all other things being equal). The Komodo dragon is today's largest lizard, but the largest lizards ever are still found in larger areas. Megalania which lived in Austraila, and may have co-existed with humans grew twice as large as Varanus komodoensis.

Wow you even know about Megalania. I mean we genuinely do share ome common interests & passions. But then agian you cant say that those Tigers lived in an area of low prey density cuz it is a Jungle. Also I was interested in asking you some thing like have you heard of some thing like the Thylacoleo & Thylacosmilus. Also do you know any thing about ancestral forms of the Cheetah?

Any ways I have a couple of videos of Natural History with me, & was wanting to know if you wanted some from me?

Freindly deal if so ;)

Here was the topic about Giant Lemurs

Yes I am very interested in Natural History, and studied it for many years. About tigers, they need to prey on large animals over 50 kg. Jungles might have more small animals, but such large animals are not common in the forest of Sumatra or Bali. Tigers need large amounts of megafauna, where as eagles don't.

Tigers have higher densities if the availability of prey is higher. The following entries are listed in decreasing order of the density of ungulate prey (Nowell & Jackson 1996):

* 0.12 individuals/sq km (0.3 individuals/sq mi) (Nagarhole, India)

* 0.1 individuals/sq km (0.3 individuals/sq mi) (Ranthambore, India)

* 0.09 individuals/sq km (0.2 individuals/sq mi) (Chitwan, Nepal)

* 0.07 individuals/sq km (0.2 individuals/sq mi) (Kanha, India)

* 0.04 adults/sq km (0.1 adults/sq mi) (Bengkulu, Sumatra, Indonesia)

* 0.01 - 0.02 adults/sq km (0.03 - 0.06 adults/sq mi) (Gunung Leuser, Sumatra, Indonesia)

* 0.01 adults/sq km (0.03 adults/sq mi) (Huai Kha Khaeng, Thailand)

* 0.006 - 0.009 individuals/sq km (0.02 individuals/sq mi) (Lazovsky, Russia)

* 0.001 - 0.005 individuals/sq km (0.003 - 0.01 individuals/sq mi) (Sikhote Alin, Russia).

Note that Sumatra is at the near bottom (in ungulate prey) of the list and is second only to Thailand which may house tigers of similar size to the Sunda Island variety (130 kg), and Amur tigers which grow to large sizes under Bergmann's rule (cold weather). Because of this, it rivals the large Bengal tiger in size (220 kg). Megafauna often favor more open areas than jungles, perhaps because of jungles ability to restrict movement. So there is three main factors at play with, area size, prey density, and temperature.

Thylacoleo - marsupial lion, and was a moderately large marsupial carnivore from the Pleistocene era. However, its name is a misnomer because it is not related to cats. I reckon Thylacosmilus would mean something along the lines of "marsupial sabre" or "pouch sabre" and was a carnivorous marsupial that looked similar (but was unrelated also) to the now extinct sabre toothed cats such as Smilodon Fatalis.

What kind of videos do you have? I'll check your other topic.

I see well as far as the various locations you have quoted with regards to the relationship b/w Tiger size & Prey availaibility, I was just curious that why no mention of Pakistan was made?

Because the thing is there are records of Tiger presence in areas right up to the border with Pakistan, then agin in Pakistan there is also plenty of natural habitat for such animals to survive undisturbed. I mean we even have Snow Leopards as well.

There is also an Iranian race of Tigers known as Caspian or something like that if I am not mistaken. There ia also the last strong hold of the Asiatic Cheetah in Iran & that they were seeking help to preserve the species from conservation agencies. I was also thinking of starting a topic with regards to Cheethas as well.

Now about that Thylacoleo Creature. Well in my humble opinion if you ask me it would have actually been an omnivore more like a bear of some sort. Bears go for both Red & Green in dietary preferances. Also by looking at its unique Dental structure I think it is an all purpose tool kit for an omnivorous life style. Think of it those rodent like front teeth are good for breaking into hard nut shells & getting at the precious seeds much like an agouti does today in the Amazon Forest then those teeth by the sides well it can do any thing with them be it tearing & cutting into muscle & flesh or further cracking nuts or processing green matter, it might have also been able to catch fish & cut them up quite easily even scale them if you ask me with its side jaws much like a bear does with Salmon Swimming up stream to Spawn. Also those side Jaws are unoque if you ask me as the teeth seem fused togeather as one if I am not mistaken, then again I think so its teeth might have also been able to continously grow from the root or bottom much like with Grazing Animals. I also think that with a mixed diet it could have been a brilliant creature with a high IQ.

Thylacosmilus lived in South America and it is cited as a case of parallel evolution.

Regarding the Videos well I have got them on topics like Whale evolution, Genome Analysis of Duck Billed Platypus & I have also got 3 videos about the Thylacoleo. I really dont know how to send them as it doesnt work by email.

Actually eagles do get quite large, to sizes comparable to that of a human child at least.

Then some can even prey on sheep & live stock as well.

There is also an eagle in New Zealand by the name of Haasts Eagle which has the largest wingspan.

Also yes I have seen an up close photo of a Phillipine Eagle & it was of awe inspiring shape & propportions.

Are you interested in keeping one as a pet...? ;)

Raptors are beautiful-excluding the owl. It's too scary looking-plus it sounds scary too.

Well it all depends from person to person as different people have their own different views. For instance some people find the owl as Cute & adorible whereas in Western Culture it is perceived as a symbol of Wisdom "The Wise Owl" if you remember. Then some people considor it as inauspicous & a symbol and Harbringer of Misfortune.

So it depends on whom you ask.

There was an article by an Urdu Sattirist named Shaukat Thavi about the Owl in which he said that in fact it is people who are worse creatures on account of selfishness & other such evils & misfortunes are also the product of ones own doings & mistakes.
