Isn’t he beautiful?? Gorillas are the largest of all primates, and adult males can weigh up to around 250kg (around 550 lb). Females weigh about half the size of males.

Gorillas are highly intelligent, make use of tools, and in captivity, some Gorillas have been taught to use sign-language.

The main threats to Gorillas include commercial hunting (both for bushmeat and trophy hunting), loss of habitat due to logging and climate change, and the Ebola virus.

This photo was taken in captivity at Melbourne Zoo in Australia.

Life as a Safari Guide: A Kruger Leopard Encounter

Leopard

Leopard, S130 Kruger National Park, by Anna Tinker

It feels like we’re already well into 2012, but this week I’ve been remembering some of the best moments of last year, and looking forward to the best of this year.

Last year, I had the wonderful opportunity to work as a safari guide in Kruger Park. During this time, there were so many unforgettable wildlife encounters, but this one was certainly a highlight for me!

I first spotted this leopard from quite a distance. I could see her sitting in the grass at the road’s edge and I stopped. From past experience, I knew that leopards will usually bolt for cover when they realize they’ve been seen.

But this one didn’t bolt at all! When I pulled up beside her, she casually stood up, walked a few feet away and flopped back down again. We watched for close to 10 minutes as she walked around in the bushes by the vehicle. I couldn’t believe how relaxed she was!

She even walked out into the road. I tried to film it, but I was just too excited to hold the camera. We were the only vehicle at this sighting, and if you’ve been to Kruger Park, you’ll understand that in itself is tremendously special.

It’s estimated that Kruger National Park holds about 1,000 leopards, but unlike this one, most of them prefer to stay undercover and aren’t commonly seen.

Will YOU be looking for leopards in 2012? I know I will! And have you got any great leopard encounters to share with us?

Nope, he’s not sleepy: “yawning” by hippos is a threat display, used by both male and female, young and old alike, to show off their massive (and very sharp) tusks.

In fact, their tusks are so sharp, they are able to bite a 3 metre crocodile in half.

A Wild ‘Wallaby Safari’… on the Isle of Man?

By Anna Tinker

I wanted to spend the first day of 2012 doing something a little different. So I dressed my parents in khakis, handed them binoculars and piled them into the car for a ‘Wallaby Safari’.  This is not normal.

We live in the middle of the Irish Sea on the Isle of Man. Few people (even those who live here) know about the 100 or so Red-Necked Wallabies we’ve got living wild in the north of our island- all descendents of one legendary pair who escaped from a wildlife park in the early 1970’s.

I’m happy to report that our ‘safari’ was successful. Just as darkness descended and the freezing wind had forced us back to our car, I noticed two large, black figures in the field. Binoculars confirmed them to be a pair of our special Wallabies. Being perhaps the most thrilling of the Island’s wildlife, the sighting certainly made for an exciting start to 2012.

But it got me thinking.

Our wild Wallaby population is steadily growing and their range is thought to be expanding. Our Wallabies are said to inhabit the same ecological niche as hares and they don’t seem to be outcompeting our local hare population for the vegetation they both like to eat. On the surface, it seems they’ve slotted in nicely up in the Curraghs where they’ve taken up home. There’s been little research into the ecological impact of these wallabies on the Isle of Man but for now their presence hasn’t generated much concern.

I’m not sure how to feel about our Wallabies. I know about the massive and devastating consequences that introduced species can bring to an environment. I recently wrote about the impact of the introduced European Fox on Tasmania’s fragile Quoll population. This is one of countless examples.

Entire ecosystems can be and are thrown fatally out of balance by introduced species. Species are often driven to extinction, and rarely does an ‘alien’ introduction fail to leave a threatening impact somewhere in its new environment.

But yet I feel a special affection to ‘my’ wallabies. As long (and only as long) as they aren’t having a negative impact on our indigenous wildlife, the wallabies add a sense of exoticism and excitement to our little island. In this moment in time, I like that I live somewhere where I can go on the occasional ‘wallaby safari’.  Is this selfish? Is it naive?   There is much to learn and explore here, and many questions to be asked.  The treatment of Introduced species will always provoke strong debate, both ecological and emotional.

So I’d like to know…

What are your thoughts about introduced species? Can they ever be ‘okay’? Have you got any stories, examples or opinions you’d like to share?

Looking back on 2011: Rhinos Under Threat. Again.

Kate

by Kate Booker

In the good old days, rhino conservation was one of the good news stories.  Hunted to the edge of extinction from the 1970s through to 1993, the rhino population was decimated and  Black Rhino numbers fell from 65,000 to less than 3,000.

Then an international ban in the trade in rhino horn in 1993, and epic conservation efforts in the field meant that rhinos were on their way up again.  The Black Rhino were the poster boys of conservation success!

But not for long…

In recent years, illegal demand for rhino horn has resurfaced in a big way, and in 2011, rhinos have once again been poached in unprecedented numbers.  All species of rhinoceros are on the IUCN Red List for Threatened Species, and 3 species are currently categorised as “critically endangered”.

In just one country, South Africa, around 400 rhino have been poached in 2011 alone.  A decade ago, this figure was around 6 or 7 animals a year.  But rhinos are under threat not just in South Africa, but throughout the continent of Africa, and Asia too – these 400 animals are undoubtedly just the tip of the iceberg.

And we will remember 2011 as the year two subspecies of rhino are gone forever: the last Vietnamese Javan Rhino was killed for her horn early this year, and just a few months later the Western Black Rhino was also declared officially extinct.

Sumatran Rhino

Why has demand for poached rhino sky-rocketed this year? It seems to be almost entirely because of a crazy rumour that powdered rhino horn cures everything from cancer to impotence.

Rhino horn is actually made of “agglutinated hair”.  Sounds a bit icky, doesn’t it?  And it is – it basically means hair stuck together.  Yup, if someone’s ingesting powdered rhino horn, they may as well be chewing hair for all the good it will do them.  And scientists have shown this.  Repeatedly.

But the fact that rhino horn has absolutely no medicinal value at all is to me actually the most tragic part of the story, for there are thousands of people who nonetheless believe this, and they are driving the demand which drives the brutal slaughter in these critically endangered animals.

This just goes to illustrate how important public education is for conservation, for without it, our efforts in the field, wonderful as they may be, are ultimately for nothing.

In Africa, both species of Rhino are on the IUCN Red List for Threatened Species:

The White Rhino (Ceratotherium simum) is “near threatened
The Black Rhino (
Diceros bicornis) is “critically endangered

In Asia, all 3 species of Rhino are on the IUCN Red List for Threatened Species:

The Indian Rhino (
Rhinoceros unicornis) is “vulnerable
The Javan Rhino (
Rhinoceros sondaicus) is “critically endangered
The Sumatran Rhino (Dicerorhinus sumatrensis) is “critically endangered

Looking back on 2011: Frozen Planet’s Polar Bear Cubs

Kate

by Kate Booker

One of the most memorable events of 2011 for me was yet another magnificent piece of wildlife television from Sir David Attenborough: The Frozen Planet.

Since watching Life on Earth as a child back in the 1970s, I have looked forward to new David Attenborough programs like most children look forward to Christmas, except they come around even more rarely, and are perhaps even more exciting.

And The Frozen Planet certainly didn’t disappoint.

But after the series premiered to seemingly universal acclaim, there was controversy when the program’s own blog on the BBC website revealed that some extraordinary footage of newborn polar bear cubs in a den was not filmed in the wild but in a Dutch Zoo.  A media storm ensued and debate raged over whether this footage was therefore “faked”.

Polar Bear Cubs

We all know that wildlife documentaries (as with other documentaries) are put together from material filmed over a period of hours, days or even months. And that therefore footage filmed on different days or in different areas or even showing different individual animals is often spliced together to tell a cohesive “story”.  I think most of today’s viewers are sophisticated enough to be aware of this, and that we accept it.

In fact, we all know it’s common practice in documentaries or news stories about people for situations to be re-created (even staged) for the camera to show how something happened, for example showing someone receiving a phone call which we know has already happened.

And of course a lot of footage always ends up on the editing room floor – we fully accept we’re getting an edited version of events.

Polar Bear and Cubs

With wildlife documentaries, especially those filmed with dangerous animals and in inhospitable climates, another element must be considered: the safety of the film crew and the animals themselves.

So documentaries – whether about humans or animals – don’t necessarily show reality as it actually happened, but a good documentary nonetheless reflects a truthful portrayal of reality, and I believe this one did just that: it showed the entirely natural denning behaviour of polar bears, and placed this in context of the polar bear’s life-story.

My own opinion is that filming this segment in a zoo was a legitimate way to obtain the footage, but there was unarguably an implication (if only through omission) that it was filmed in the wild, and on this occasion it would have been appropriate to mention this in the narrative.

Polar Bear and Cub

At the time that segment was shown, I genuinely assumed it was shot in the wild and admit I was tremendously curious.  My husband and I actually discussed how on earth they must have filmed it.  It would have been nice to know where and how such extraordinary footage was shot, if only to satisfy my (and no doubt others’) curiosity, and if I were the documentary maker, I do think I would have mentioned it was filmed in a zoo.

Does this slight shadow detract from the footage?  In my opinion not at all: the footage of those tiny cubs was magical in a take-your-breath-away kind of way, one of the most memorable of the whole series.

(If you haven’t seen it or would like to see it again,
the original polar bear cub footage is shown on the BBC’s website.)

I suspect this is a live-and-learn situation for the BBC, and documentary makers in general.  Yes, we’re a sophisticated audience, but we do make certain assumptions, and we expect transparency from our media.  Goodness knows as the phone hacking scandal which has erupted in the UK this past year shows, there’s little enough integrity out there.  And perhaps we expect more from the BBC and Sir David himself, and hold them to higher standards.

But let’s forget this detail for a moment and focus on the big picture.  Overall, The Frozen Planet was a superb piece of documentary film-making, with some of the most memorable footage ever shot.  Did it educate? Did it entertain? Did it inspire? You bet – we were enthralled!

I wonder how many adults today (like myself) have a fascination with or appreciation of the natural world or perhaps even work in the wildlife or conservation field because of Sir David Attenborough’s wonderful work?

And how many adults of tomorrow were similarly touched by seeing Sir David’s work for the first time on The Frozen Planet?

What a wonderful legacy.

This beautiful and elusive cat lives in the mountain ranges of Central and South Asia. Their secretive nature means that their exact numbers are unknown, but it is estimated that only around 3,500 – 7,000 snow leopards still exist in the wild.

Hyenas get a bad rap but they’re amazing animals.  (And don’t they have the sweetest faces??)

They’re often described as “scavengers”, but they’re actually excellent hunters.  Spotted Hyenas have a hunting success rate which is far better than lions (around 75% of hyena clan hunts are successful, compared to only around 30% of lion hunts.)

Meet the Enchanting Eastern Quoll

Eastern Quolls at the Tasmanian Devil Conservation Park, Tasmania, by Anna Tinker

Here’s one of those ‘lesser known’ animals. The sort that you may go your whole life without knowing about.

Which is a pity because the enchanting Eastern Quoll is one of Australia’s smallest and most endearing marsupials. They have lovely little toes, pink button noses and are exceptionally dotty. Now here’s the bit we don’t like: over the last 40 years, it’s become extinct on the Australian mainland and is now found only on the island of Tasmania, where I photographed these little guys.

Traditionally, they’ve been threatened by habitat loss and predators such as feral cats- a huge problem in Australia. It’s thought that they survived in Tasmania because of its lack of dingoes and foxes. But since 2000 and despite conservation efforts, the European Red Fox has been present in Tasmania and poses a huge threat to the state’s unique and precious wildlife, especially its Quolls.

What Can I do?

Do a little research and learn about the often devastating impact that non-indigenous species can have on an environment. Have a look at this website: Parks and Wildlife Service Tasmania. And if you’re lucky enough to visit the unforgettable island of Tasmania, go and drop in on these friendly people and see what fabulous work they’re doing at the Tasmanian Devil Conservation Park.

Not in love yet? Watch this pair of munching marsupials crunch their lunch!

The Eastern Quoll (Dasyurus viverrinus) is extinct in mainland Australia but has a reasonably stable population in Tasmania where it is now listed on the IUCN Red List for Threatened Species as “near threatened

Elephants: separating the girls from the boys

Did you know you can tell the gender of an adult African elephant from the shape of its head?

When viewed from the side, female elephants (cows) have a forehead which rises up almost vertically, then angles back at almost 90 degrees, giving it an angular, almost square appearance.

Bulls’ foreheads, on the other hand, are much rounder and slope gently back.

Pretty cool, huh?

..

Of course there are other ways to tell elephants apart – but not necessarily what you’d think.  Checking their genitals can be misleading because males have internal testes, but cows have mammary glands between their front legs, rather than their rear legs – the only mammal other than primates to have them here.

But the best way to tell male and female elephants apart, at least in the wild, is to look at who they’re hanging out with.  Females generally live in large, close-knit social groups called  ”breeding herds”, which generally will have one or more babies or youngsters.  Males on the other hand are either solitary or live in smaller, less close “bachelor” groups of adolescent and adult males – no babies.
