I Need Your Help for Wildlife Blogger of the Year!

November 10, 2018November 9, 2018 | Rebecca Gibson

If you love wildlife, then I need your help!

I’ve entered the Wildlife Blogger of the Year 2018 competition, organised by Terra Incognita. The theme is “a favourite wildlife moment of 2018”, and I chose my encounter with a wild grey seal in the Farne Islands, which some of you may remember reading about.

I chose this story because it was an incredibly special experience and a reminder to me that we should not be constantly connected to technology. I had a GoPro with me while I was snorkelling but was so surprised by what happened that I completely forgot to film. At first I was disappointed, but on reflection I am so glad that I stayed in the moment and didn’t miss a single second. I interacted with a wild animal with absolutely no distractions, and it has become one of my most precious memories of time spent in nature. I hope my story reinforces the need to connect with wildlife and shows just how rewarding it can be.

As well as the overall winner of Wildlife Blogger of the Year, picked by a panel of judges, there is the Reader’s Choice winner award, which anyone can vote for. If you enjoy my story, I would be thrilled if you could cast me your vote.

Learning to Dive – Part One

November 6, 2018November 6, 2018 | Rebecca Gibson

The alarm went off at 6am and my stomach began to churn. Today was the start of Open Water weekend, and if all went well, I would earn my first diving certification. Having struggled with some of the skills in the swimming pool, not to mention the fact I was still getting used to all the kit, I couldn’t help feeling apprehensive as I pulled on my warmest clothes. I hastily gobbled a petrol station flapjack, which tasted like cardboard in my dry mouth. Knowing I shouldn’t be feeling so anxious, I tried to shake the nerves and triple-checked I had everything I needed.

Luckily, the site was only a five-minute drive from the hotel, and I arrived in plenty of time. Stoney Cove used to be a stone quarry that was used in the 1960s and 70s to train commercial divers and test underwater equipment used in oil fields. Now, Stoney Cove has conference rooms, shower facilities, a shop and – most importantly after a tiring dive – a pub called Nemo’s. The actual quarry is a multi-level city of shipwrecks and aquatic life, split up into areas of different depths for divers of all abilities. As this was our first open water dive, we stayed safely in the 7m limit, which still contained a submarine and an aircraft cockpit. Although, I was more interested in the crayfish, perch, roach and pike that called Stoney Cove home.

It was a cold but clear day, with sunlight pouring weakly onto the water. No rain at least, though I suppose rain shouldn’t really be a concern for divers. As I stood at the quarry’s edge watching seagulls floating on the surface, I couldn’t quite believe I would soon be diving several metres beneath it.

Soon it was time to start kitting up. We assembled in buddy pairs and helped each other don scuba kits just like every week at the pool. This time, however, we also had hoods, gloves, compasses and a dive computer. We made our way down to the ramp, where several divers were already in the water. For dive one all we had to do to enter the water was stand on the edge and sit gently back, floating out into the quarry.

Ungainly as always with my cylinder and weights, I felt like a tortoise on its back as I tried to strap on my fins. Eventually I was ready, and made my way hesitantly to the edge of the ramp. I turned, squatted and leaned back. The shock of freezing cold water rushing into my wetsuit wasn’t exactly comfortable, but in a strange way it was exhilarating. This was it, time to dive.

Once everyone was in the water, we began our first descent. As more of my body became submerged, I soon grew numb to the cold and instead focussed on the underwater world we were entering into. I descended to the bottom, making sure to equalise my ears to the increasing pressure, and looked around. The visibility wasn’t superb and the only features I could make out were other divers, but the murkiness only added to the suspense. It still felt strange not to have to work to stay down in the water, instead floating effortlessly.

The instructors led us on a swim, past the Nautilus submarine to a wooden platform where we would perform our skills. An underwater classroom surrounded by shipwrecks and fish; it was quite extraordinary.

After each taking turns to carry out the skills, we started our ascent. For the first time on the dive I looked up, and the sight was breathtaking. Sunlight streamed through the water in slanted shards that lit up our bubbles as they cascaded upwards. I still hadn’t got my head around being able to breathe underwater. It had been a dream of mine as a child, pretending to be a dolphin in the local pool. I wasn’t quite a dolphin yet, but I was closer to the underwater world than ever before.

Coming soon: day two of Open Water weekend!

Why are Island Tortoises so Large?

October 29, 2018October 29, 2018 | Rebecca Gibson

New research has shown that giant tortoises may not be large because of their island lifestyle, as previously thought. A team of researchers has gathered extensive genetic data from both living species and fossils of extinct species to discover the truth of how tortoises have evolved, in an attempt to answer the question of how they have become such giants.

Tortoises are an extremely diverse group of animals, ranging in size from 8cm long to one metre long. The largest species is the Galápagos tortoise, which can weigh nearly 500kg. So why has gigantism evolved in tortoises? Despite studies on these fascinating animals since Darwinian times, the answer is still unclear. It was thought that, like many species, tortoises followed the “island rule”: a tendency of dwarfism among large animals and gigantism of small animals living on islands. For example, in mainland Florida the white-tailed deer is abundant, but in the Florida Keys – a tropical archipelago of islands off the south coast of the state – a dwarf version of the mainland deer is found, known as the Florida key deer.

It is thought that island dwarfism is caused by limited resources, while a reduced pressure from predators triggers island gigantism. However, in the case of tortoises, it was suggested that these animals were already large in size before colonising remote island habitats. With so many giant tortoise species now extinct, it is impossible to uncover the reason behind gigantism in these animals without using the fossil record.

Now, Dr Evangelos Vlachos from the Paleontological Museum of Trelew in Argentina and Dr Márton Rabi from the Martin Luther University Halle-Wittenberg put together the most complete family tree of both extinct and surviving tortoise species so far, in an attempt to piece together the reasons for their variation in size. Interestingly, it was discovered that gigantism occurred on the mainland too, in Africa, Europe, Asia, North and South America. Interestingly, all of these mainland species became extinct.

“The fossils highlight a great number of extinct mainland giant species and suggest that the evolution of giant size was not linked to islands,” says Dr Evangelos Vlachos, “We expect that warmer climate and predator pressure plays a role in the evolution of giant size but the picture is complex and our sampling of the fossil record is still limited.”

So what led to the extinction of these giant mainland tortoises, and why have their island variants survived? It is thought that predation and climate change contributed to these extinctions, but it is intriguing to think that the island rule may not be the overriding factor for giant evolution, calling for more research into what causes such variation in size among these animals.

Tortoises have roamed the planet for over 55 million years – they survived the mass extinction that wiped out the dinosaurs, but now face an even graver threat: people. Human-induced habitat loss is the most significant threat for tortoises today, and they face an uncertain future. Thanks to research such as Vlachos’ and Rabi’s, we are able to better understand how these successful animals have evolved, and will hopefully continue to evolve for many more years to come.

To Catch A Fly

October 22, 2018 | Rebecca Gibson

Fly agaric, or Amanita muscaria, is perhaps one of the most recognised mushrooms in the UK. It is often used as perching posts for pixies and gnomes in storybooks, and can regularly be seen bringing a spot of colour to the forest landscape. With its blood red cap and white spots, it’s almost unmistakable. Fly agaric can be found from late summer throughout winter, dotted around birch, spruce and pine trees.

As is often the case in the natural world, pretty means dangerous. With a name derived from its ability to kill flies, fly agaric has been widely used as an insecticide. It is a poisonous mushroom known for its hallucinogenic properties but, despite this, it has been a part of religious tradition for thousands of years. In Hindu practice, fly agaric was supposedly used to produce a psychedelic drink called soma, taken as part of religious ceremonies to increase one’s awareness and evoke sensations of bliss, poetic inspiration and even immortality. However, there has been disagreement among modern scholars over the exact ingredients in this psychoactive beverage. Soma has been described as containing a plant with leaves and flowers, contrast to fly agaric.

Elsewhere in ancient history, fly agaric was consumed in potion-form by Vikings in the 8^th century, allowing them to fight in battles with increased frenzy. And of course, Alice used the mushroom to change her size in Wonderland, after being instructed to do so by a smoking caterpillar with a ‘languid, sleepy voice’.

Though perhaps this wouldn’t be the recommended theme in modern children’s literature, it shows that the mysterious fly agaric has woven a complex and intriguing story through the ages. Now, as autumn descends, the fungi season is in full swing. Fly agaric sits radiantly among more drab varieties of mushroom, its vibrant colour a dangerous lure. It is a specimen that has fascinated us for centuries, and will continue to intrigue long into the future.

A Silent Extinction

October 7, 2018October 7, 2018 | Rebecca Gibson

Giraffe have always been special to me. Even with long, gangly limbs, they move with unhurried poise and confidence, but still look endearing with their huge eyes and long eyelashes.

On TV this week there was a repeat of an episode in Attenborough’s Natural World series: Africa’s Gentle Giants. The story centred on Dr Julian Fennessy, Co-Founder and Co-Director of Giraffe Conservation Foundation. Fennessy has been working to conserve giraffe for more than 20 years, and is a true pioneer in research on this secretive and surprisingly little-known animal.

Many people, including myself until very recently, are naïve to the true situation that wild giraffe currently face. Among other African species such as elephants, gorillas and leopards, for some reason giraffe have taken a backseat in the public eye. While words like “beautiful” and “majestic” always spring to mind when we talk about giraffe, how many of us could confidently say how many there were? I was shocked to discover how wrong I was when giraffe statistics were presented alongside those of another African giant. Currently, there are around 500,000 African elephants left, but only 90,000 giraffe. For the first time ever, I doubted what David Attenborough was telling me. How could that be possible? I began to look online, but of course it was true. There are nearly five times as many African elephants than giraffe left on the planet. It’s a statistic that astounded me.

Giraffe are not only unmistakable symbols of Africa and the tallest animal on Earth, but they are important to the ecosystem. Like bees, giraffe are excellent pollinators, and pass pollen from tree to tree as they graze. They also spread seeds in their dung, another vital part of maintaining a diverse and sustainable landscape. Conserving giraffe protects not only the animal but its environment, ultimately affecting so many other species that call Africa home.

In two decades, giraffe numbers have fallen by 40% and they have become extinct in seven countries. They are hunted for meat and their habitats are slowly disappearing. One of the most vulnerable populations – a group of less than a thousand Rothschild’s giraffe – lives in Murchison Falls National Park in Uganda. These animals are walking on a literal time bomb; beneath their feet lies 75% of Uganda’s discovered oil, and Fennessy knew that plans to drill would spell disaster for these endangered animals. His ambitious and dangerous mission was to relocate twenty giraffe from one side of the River Nile to the other, where it was hoped that these pioneering individuals would start a new population in a safer location.

As I watched the team of dedicated vets, rangers and scientists attempt to move one-ton animals whose kick could decapitate a man, I was filled with such admiration and respect. It is all very commendable to donate money to charity, but these people were out in conflict areas risking their lives for giraffe. As the mission progressed, I got quite emotional, not just because the threats these beautiful animals face are so unnecessary and unjust, but because I was completely unaware. What little chance these animals have if even wildlife enthusiasts like me don’t know their situation.

It wasn’t just the numbers of giraffe that I was unaware of; so much of their behaviour remains unseen to even experts like Fennessy who have studied them for a vast proportion of their lives. By the Hoanib River in northwest Namibia, he took a sensitive camera out to film giraffe at night. As he watched, a giraffe curled up on the exposed ground and fell asleep. It was something Fennessy had never witnessed before.

“In zoos they study it,” he explained, “Basically when their neck is down it’s REM sleep, so maybe these giraffe are dreaming. I’ve never seen that in the wild.”

The fact that we don’t know how wild giraffe sleep says a lot about how overlooked they are. It seems there is the assumption that because we don’t hear about a particular animal as much, it must be doing fine. However, in the case of the giraffe this couldn’t be further from the truth. So why do we know so little about these animals? Perhaps it is because they are only listed as “Vulnerable” on the IUCN Red List of Endangered Species. An article published two years ago, at the time that this episode was first released, hopes that the work Fennessy is doing will help change the status of giraffe to “Endangered” or “Critically Endangered” and therefore encourage greater conservation efforts. Unfortunately, as 2018 draws to a close, the giraffe is still listed as “Vulnerable”. I can only hope that this change in status does come into effect to raise awareness of this silent and rapid extinction that is passing so many of us by, or soon it may be too late.

Up in the Air

September 26, 2018 | Rebecca Gibson

The plane roared to life and I experienced the age-old feeling of excitement whenever I fly. As we chased the runway and the plane slowly lifted, I pressed my face to the window to see the ground fall away. I will never tire of that feeling of utter weightlessness – the peculiar thought of something so bulky taking to the air.

I’d been invited onto my boss’s plane for a morning trip to Naples, a city in southwest Florida looking out onto the Gulf of Mexico. We were flying to break in a new engine, and planned to refuel in Naples before returning to Yulee. It was a whistle-stop state tour, a four hour round trip that would take twelve in a car.

Within moments of take-off we were over the beach – long piers stretched out into the sea like the teeth of a comb. At 9am on a Saturday the beach was almost deserted. It was a treat to see so much uninterrupted sand before the tourist tide came rushing in.

We curved back inland and passed over a maze of river and marshland that I had already explored by boat, but this time we were too high to look for egrets. The only movement was the white streak of a lonely boat as it navigated the watery trails. I wondered how many alligators were down there, then decided not to think about that.

The marshy solitude of Amelia Island dissolved into towering office blocks, and I soon recognised downtown Jacksonville. There was the Landing, where I’d been just a week before the shooting. It had been enough to dissuade me from visiting downtown again, but I still had fond memories of the river walk, the MOSH museum and the topaz blue water of Friendship Fountain.

Leaving vast, sprawling Jacksonville behind, the landscape was soon dominated by trees again. Green was undoubtedly a primary colour in Florida – a patchwork quilt of field and forest stretched as far as the eye could see. In some places the trees were confined in tightly packed cubic parameters. In others, they were sprinkled sporadically. Criss-crossed over it all were the highways, dead straight lines in parallel and perpendicular.

Fluffy cumulus clouds were gathering, and a rather ominous feeling began to grow in my stomach as we bumped over them. Sunlight poured into the stuffy cabin, which did nothing to suppress my queasiness. Because of the new engine, we had no choice but to fly low. While the views were still stunning, I was somewhat distracted by the turbulent ride, and as Naples came into view I couldn’t help feeling slightly relieved that we’d be getting out of the clouds.

Once down on the ground, we stopped just long enough to stock up on drinks – fuel for the plane, a Gatorade for me – before taking off again, back through the spectrum of concrete jungles and green wildernesses.

The Greenway

September 10, 2018 | Rebecca Gibson

The Egan’s Greenway is an unexpected jungle in the middle of smoke-belching industry and deckchair tourism. The mundane sounds of traffic are deafened by the furious chatter of cicadas – enormous insects that seem prehistoric. Their strange call is like the sound of angry water sprinklers, growing louder and faster until it reaches an alarming tempo, then abruptly stops.

At first light the Greenway is sharply divided into light and dark. The dense, impenetrable forests are still cool – the trees in muted greens – but out on the marsh the grass is alight with fiery golds and oranges. Naked trees poke the sky with sharp limbs white as bone, while beside them sway lush evergreens. It is a land of stark contrast, a spectrum of vitality and decay. Time passes here with the tick of the cicadas.

The day warms up, throwing a shimmer onto the surface of the creek. Here there be dragons, some cruising between reeds on transparent wings, others scrambling up trees with long claws. A flash of movement and then a disappearing act, they blend seamlessly into their surroundings. Just a flick of the beady eye will give them away, and then they will shoot off into the undergrowth.

Other beasts can be found higher up. Perched on the skeleton fingers are ospreys, scanning the creek in every direction. One takes to the air and its mate follows. Together they wheel in deep circles, overlapping in smooth figures of eight. A wood stork, large enough to be unfazed by the raptors, joins their sky with dark wings barely flapping.

Then, a real dinosaur. A creature that survived what forty-metre sauropods could not, almost unchanged for millions of years. This one is only small, an arm’s length perhaps, but even so it floats beneath the water’s surface with the stealth of an adult, startling green eyes always watching. A glance away and back again and it has disappeared, moving across the creek without a sound.

Where is mum? Perhaps it is best not to stay and find out.

Searching for Spoons

September 3, 2018March 11, 2020 | Rebecca Gibson

After so much excitement, I’ve neglected my camera recently and wanted to finally spend some proper time searching for Florida’s wildlife. I’d been told about a good spot for wading birds, and knew that the inhabitants included my new favourite bird, the roseate spoonbill. I set out before sunrise and reached the water just as the sky was beginning to lighten; pinks and oranges blending with blue.

My first sighting was almost immediate. Perched on a branch overhanging the lake and peering curiously as I wound down the window was an anhinga. With both heron and cormorant-like features, anhingas spear fish under the water with their long, sharp bills. The name originates from the Brazilian Tupi language and translates as “devil bird”. I don’t quite see the devilish resemblance – I found the anhinga delightful, especially when it shook out its striped wings. Like cormorants, anhingas hold out their wings after swimming to dry them. This one looked like either a female or a juvenile, as males are jet black with silvery streaks.

Soon the anhinga was joined by a yellow-crowned night heron, shoulders hunched down as if with cold. With a white cheek patch and a pale crown of feathers that looks more white than yellow, the yellow-crowned night heron is actually nocturnal, so I must have been really lucky to catch a late glimpse just before the sun emerged.

Elsewhere in the tree was a green heron, who was more brown than green so was perhaps a juvenile. Apparently, green herons are known to throw insects into the water to encourage fish to the surface, which is genius and must look amazing to see.

Suddenly a snowy egret burst into view, legs dangling and panicked wings flapping. There was a deep, kronking call as more birds surged upwards. Puzzled, I glanced around for signs of a raptor, when a disturbance in the water caught my eye. There, gliding without a sound, was an alligator. My first alligator! I could hardly contain myself. All I could see of it was a pair of eyes and nostrils, so I had no idea how big it was, which was perhaps more nerve-wracking than seeing the whole animal. Even from the safety of the car my paranoia imagined the alligator leaping headlong at the open window, but it just cruised out of sight and the birds soon calmed down.

I wandered further on to try and find a spoonbill. There was a loud rustling above and I looked up to see the trees absolutely covered in white ibis; wading birds that gather in large groups all across Florida. I was spoilt for choice for photos. Although they’re not the prettiest of birds, their long, red bills still looked impressive, especially when they all took off in one simultaneous swoop. In the absence of car engines and people this early on a Sunday, the only sound to be heard was the wind in their wings which sounded so magical.

After watching them leave I wondered what had scared them off. Once again I scanned the trees for signs of a raptor and this time I found one: a stunning osprey with a fish in its claws! I’d only seen ospreys once before in Scotland, all the way across a loch that made taking photos quite the challenge. This osprey, however, was a tree’s height away and sat in a perfect patch of sunlight that made its yellow eyes dazzle. It spotted me straight away and watched as I took photo after photo. Eventually it gathered up its breakfast and took off, just as the first dog walker came into view.

At 9:30am it was already getting too hot to be out without a hat, and my hastily eaten bowl of cereal at 6am seemed far away. I’d loved to have found my spoonbill, but having seen a bonus osprey and alligator I was far from disappointed. I’d just got back to the car and was fumbling for my keys when I glanced up, and by some miracle there was a spoonbill perched at the very top of a tree. It was the pink cherry on an incredible cake.

More to See, More to Zoo

August 25, 2018October 6, 2018 | Rebecca Gibson

Meeting the giraffes of Jacksonville

Last week I visited Jacksonville Zoo, which boasts “more to see, more to zoo”. And it certainly delivered, with a broad range of exhibits including some very special ones that I’d never seen before. A particularly unique exhibit was Wild Florida, a collection of species native to the state. I discovered just how big alligators are (which only confirmed my decision not to go anywhere near a river during my time here) and caught a glimpse of a manatee as it glided underwater. Manatees are the state marine mammal of Florida but threats such as collisions with boats, habitat loss and the devastating red tide have now made them endangered.

In response to these threats, Jacksonville Zoo is in the process of making the first manatee critical care centre in northeast Florida. This will allow more injured animals to be rescued and cared for, and minimise travel distance to other centres such as the ones in Miami, Tampa and Orlando. To make the experience as natural as possible for the manatees, they have a very large tank, which can only be viewed from one side. They are only seen occasionally when they swim close to the tank’s edge, giving them much needed privacy.

Elsewhere on the site was the Emerald Forest Aviary, where I met my new favourite bird: the roseate spoonbill. Native to Florida, this extraordinary wading bird is candy floss pink in colour and sports a magnificent bill that it waves from side to side underwater to sift through the mud. There was a group of them in the aviary, perched on branches overhanging a deep, dark pond. I positioned myself to put this dark pond behind a particular bird who had stood beside some very photogenic foliage. After just a little editorial tweaking, I was pleased with the dramatic result.

Although I always love seeing the star animals of the zoo, some of my best moments from the day were the wild individuals that had snuck in uninvited. As usual, I fell in love with some new lizards, including one that posed for me with an over-the-shoulder glance.

However, the most incredible moment came just before I left. I was wandering past the lions and admiring the wildflowers that were attracting all sorts of butterflies and dragonflies. Then, I saw something larger than an invertebrate zooming around and was thrilled to discover it was a hummingbird!

I fumbled to get my camera ready, and for a while took lots of blurry pictures of flowers. Eventually, I got used to the hummingbird’s pattern of flying and managed to capture the animal in frame. I stood watching it for ages, as usual receiving looks from passers-by wondering what I was so interested in. For me though, it was an amazing sight and one of those perfect surprises.
