“Majed trekked for four hours to meet Kibande, an almost-40- year-old mountain gorilla. ‘The more we climbed, the hotter and more humid it got,’ Majed recalls. As cooling rain began to fall, Kibande remained in the open, seeming to enjoy the shower.

Mountain gorillas are a subspecies of the eastern gorilla, and are found at altitudes over 1,400 metres in two isolated populations – at the Virunga volcanoes and in Bwindi. These gorillas are endangered due to habitat loss, disease, poaching and habitat disruption caused by human activity.”

“A black jacobin hovers in front of the morning sun and as the light penetrates its wings the feathers become ‘filled with rainbows’. Christian used the high clouds as a secondary filter to reveal this prism effect, otherwise invisible to the naked eye.

Hummingbirds have the fastest wingbeats in the bird world – up to 90 beats per second. As light passes through the narrow gaps in-between feathers, it is split – or diffracted – into the colours of the rainbow, creating a shimmer.”

“It was midwinter, the start of the ravens’ breeding season. Shane lay on the frozen ground using the muted light to capture the detail of the ravens’ iridescent plumage against the contrasting snow to reveal this intimate moment when their thick black bills came together.

Ravens probably mate for life. This couple exchanged gifts – moss, twigs and small stones – and preened and serenaded each other with soft warbling sounds to strengthen their relationship or ‘pair bond’.”

“Virunga National Park pilot Anthony flies two orphan chimpanzees to safety at the rehabilitation centre.

The babies were rescued from traffickers following a tip-off from locals. Baby chimps have little meat value, but are often sold as pets or for animal shows. At this stage they are unlikely to survive without specialist care, needing formula milk and regular balanced meals.”

“A red-eared slider turtle swims peacefully among the water lilies in the Aktun Ha cenote in Mexico.

The limestone rock of Mexico’s Yucatán Peninsula is dotted by thousands of cenotes, freshwater pools linked by an underground river system. Some cenotes are underground caves while others, where the rock has fallen in, are open air pools.

Henley was spellbound by the marine world below the surface. ‘It was only later that I found out this beautiful scene has a more troubling backstory,’ he says.

This unique environment is home to many species of flora and fauna including fish and turtles, but what Henley didn’t realise at the time is that the slider turtle in his image is not a native Meso-American slider, but a red-eared slider (native to the USA and northeastern Mexico).

It is likely that this turtle was once a pet, or the offspring of a former pet which was then released back into the wild. An increase in wild releases as a result of the booming pet trade has meant that slider turtles have now been successfully introduced to nearly every continent. They are now among the world’s 100 most invasive species due to their interbreeding, altering freshwater habitats and carrying pathogens.

How you can help
-Learn about the world’s wildlife and pet trade and the impact it has on the welfare of both humans and nature.
-Consider adopting a pet carefully, and never release your pets back into the wild. If you have to give them up, call a local wildlife organisation.

-Look after your local ecosystems, and learn about the species that keep them balanced.”

“From a plane, Daniel noticed this almost perfectly round hole in the ground. Inside, huge trees were thriving – a lush mix of palms, broad-leaved trees and climbers – like a ‘full-blown rainforest in a bowl’.

Chiribiquete National Park boasts an exceptional diversity of native wildlife but it is threatened by deforestation and mercury pollution from gold mining. Thanks to public and political mobilisation, the park was added to the UNESCO World Heritage list in 2018, becoming Colombia’s largest protected area.”

“Following a tip-off from local yak herders, Xiaoyun began a daily six-hour round trip to this mountain site. On the ninth day he spotted a snow leopard and three cubs sleeping among rocks. While observing the leopards with his drone, Xiaoyun noticed the remains of a blue sheep on which they had likely just fed.

Snow leopards are a vulnerable species. However, the illegalisation of firearms in China in 1989, along with hunting bans in key provinces, seems to be helping stabilise population numbers.”

“A young grey seal cries out in pain as lengths of plastic fishing rope cut deeper into its body.

Michael was photographing a seal colony along the Lincolnshire beach when he heard the agonising screams of the seal. The unlucky animal probably became entangled in this rope when it was just a pup, and it has cut deeper and deeper into its body as it grew.

Michael says, ‘The suffering and pain can be seen on its face as it screams in pain.’

He and two other photographers quickly called the local Wildlife Trust and Seal Sanctuary to free the seal and treat its wounds so that it could be released safely.

The Donna Nook National Nature Reserve on the Lincolnshire coast in the UK is a major breeding colony, with more than 2,000 pups born every year.

Cases like this are becoming increasingly common around the world as discarded fishing gear, including rope, nets and traps fill the oceans, entangling marine life such as whales and turtles.

How you can help
-If you see any marine life caught up in plastic waste, call the local wildlife trust or other nature organisation and alert them to the situation.
-Reduce the amount of plastic that you use. While most plastic in the ocean is discarded fishing gear, household items such as toothbrushes and plastic razors also contribute.

-Participate in a beach clean-up to help remove plastic from the ocean before it can cause harm to marine life.”

“This orphaned grey-headed flying fox pup was about three weeks old when it was found on the ground, probably after a fall, and taken to the Black Rock Animal Shelter. After a week of round-the-clock care, the youngster started to recover.

Female grey-headed flying foxes carry their pup during foraging flights for the first three weeks, after which they leave them behind. Young are capable of flying at three months old but are not weaned until five to six months”

“After noticing tiny spiders all over his bedroom, Gil looked under his bed. There, guarding its brood, was one of the world’s most venomous spiders. Before safely relocating it outdoors, he photographed the human-hand-sized Brazilian wandering spider using forced perspective to make it appear even larger.

Brazilian wandering spiders roam forest floors at night in search of prey such as frogs and cockroaches. Their toxic venom can be deadly to mammals including humans, but it also has medicinal uses”

“On a summer’s night Juergen searched the rainforest for bioluminescent ghost fungus. Scanning the darkness for the strange glow, faint to the naked eye, he was rewarded with this magical sight: clusters of ghost fungus seeming to climb the base of a dead tree.

The bioluminescence of ghost fungus results from a chemical interaction between a compound known as luciferin and the luciferase enzyme in the presence of oxygen. The function of this glow remains a mystery to be solved.”

“Polar bear cubs are born in winter and may suckle for two years.

Once accustomed to Martin’s boat-based camp, the bears often lingered close by. Judging the mother and cubs were untroubled by his presence, Martin left the boat and crept closer. Keeping a respectful distance, he was near enough to hear the cubs suckling and purring, ‘an unbelievable sound, like little helicopters buzzing away’.”

“A male Bornean orang-utan in China’s Yunnan Wild Animal Park grips the bars on the door between the indoor and outdoor enclosures.

Celina says, ‘The sight of him immediately brought me to tears as I stood there, helplessly watching him shake the barred hatch in the door.’

Orang-utans are a common sight in zoos and wildlife parks around the world, many of which are taken from the wild as infants. Once in captivity, they are confined to small enclosures a fraction of their usual habitat, without the stimuli needed to keep their capable brains content and happy.

This male only had a metal bed frame with a wooden plank for a mattress and a plastic bottle of flavoured drink. It had no opportunity for stimulation and appeared numb to the crowd of visitors peering into the glass enclosure.

In the wild, orang-utans spend most of their days foraging for food in the forest canopy. They use things they find in the forest to extract insects and honey for food.

How you can help
-Be an animal-friendly tourist. Don’t visit places that make money off the exploitation of animals. Instead, support local businesses that protect and care for nature.
-Protect the livelihoods of wild orang-utans by supporting organisations that conserve their rainforest habitats.

-Consider supporting an orang-utan rehabilitation project in Borneo or Sumatra which helps previously captive animals return to life in the wild.”

“After months of waiting, Sergio’s carefully set camera trap finally gave him the picture he wanted: a young Iberian lynx perfectly framed in the doorway of an abandoned hayloft on a farm in Spain.

Lynx were widespread on the Iberian Peninsula before the early 1900s. Hunting and habitat loss pushed this species to the brink of extinction by 2002, when fewer than 100 lynx could be found in Spain. Today, thanks to ongoing conservation efforts, numbers of Iberian lynx are on the rise.”

“Zack decided these bull elk remains were an ideal spot to set a camera trap. Returning to the scene was challenging. Zack bridged gushing meltwater with fallen trees, only to find his setup trashed. This was the last frame captured on the camera.

Grizzlies, a subspecies of brown bears, spend up to seven months in torpor – a light form of hibernation. Emerging in spring, they are hungry and consume a wide variety of food, including mammals.”

“Lasse wanted to give a sense of scale in his photograph of the Siberian jay, tiny among the old-growth spruce-dominated forest. He used pieces of cheese to get the jays accustomed to his remotely controlled camera and to encourage them along a particular flight path.

Siberian jays use old trees as larders. Their sticky saliva helps them glue food such as seeds, berries, small rodents and insects high up in the holes and crevices of the bark and among hanging lichens.”

“David has been diving here for more than 30 years. His images show coral ‘through the lens of time and climate change’ and are likely to become records of a vanished world.

Coral colonies are formed by thousands of tiny animals called polyps, each secreting calcium carbonate to build its own home. Polyps are fuelled by food produced by the algae living within their cells. When corals are stressed by overheating they become bleached, expelling their algae and turning white

“Flower-filled meadows full of fluttering Apollo butterflies surrounded Emelin’s family’s holiday cottage. Discovering the butterflies’ resting spot in wooded hills above the meadows, Emelin achieved his dream of photographing ‘the magnificent Apollo’.

Found at high altitudes across the mountains of Europe, Apollo butterflies are vulnerable to climate change because their life cycle relies on snow. Snow forms an insulating layer over the butterflies’ eggs, preventing them from freezing, which means that reduced snowfall can impact the butterflies’ survival.”

“Jonny and his colleague willed the red fox to reach them before the heavens opened. ‘Adjusting the manual flash was awkward,’ he says, so he pre-set the power for a soft spotlight – just enough to bring out the texture of the fox’s coat at a relatively close range.

Red foxes live in diverse habitats across the world. Jonny had followed this fox over several days, watching it forage for berries, pounce after songbirds, and playfully nip at the heels of a young brown bear.”

“A female yellow sand cichlid releases its fry from the shelter of its mouth.

After spawning, a female carries the eggs in its mouth for about three weeks as the fry develop. Once they are ready to swim, the fry are released. From that moment onward, parents will shelter the fry in their mouths when they need rest or protection.”

“The extreme heat of the Australian summer caused a group of grey-headed flying foxes to abandon their treetop roosts and collect en masse around a tree trunk, in the hope of escaping the heat of the day.

Sadly, this ‘clumping’ behaviour only exacerbates their heat stress as the bats crowd together, getting hotter. Eventually one may fall, knocking others down, creating a pile at the bottom of the tree. Unable to move, the bats get even hotter and can suffocate each other.

Doug notes how, at this colony at Yarra Bend, ‘hundreds piled up at the base of trees, dead or dying from exhaustion or suffocation’.

Local rescuers tried to save as many bats as possible by spraying them with water to cool down, however more than 4,500 are estimated to have died during this heat stress event – about 10% of the colony.

Large fruit bats like these play an important role in maintaining the health and biodiversity of forest habitats up and down the Australian coast through tree pollination and seed dispersal. They are increasingly facing catastrophic heat stress events which threaten the survival of the species.

How you can help
-If you see a group of flying foxes ‘clumping’, contact the local wildlife trust or other nature organisation and alert them to the situation.
-Talk to your friends and family about the benefits that fruit bats have to the environment

-Global warming is causing extreme temperatures all over the world, support initiatives that take action to reduce emissions and global heating.”

“A group of visitors watch and take photos as a young elephant performs tricks underwater at a zoo in Thailand.

Adam uses his photo to draw attention to the crowd watching, rather than the elephant itself, bringing into question this form of tourist entertainment.

Shows like this one are often promoted as educational and advertised as good exercise for the animals, but rights organisations are concerned for the welfare of the elephants involved. The training for this type of show usually starts with the removal of a calf from its mother and uses fear and pain-based punishment.

An increase in elephant tourism over the last few years combined with the low birth rate of elephants in captivity has driven a rise in poaching young calves from their mothers. There are now more captive elephants in Thailand (possibly 3,800) than wild ones (fewer than 3,600).

Around the world, animals are held captive and deprived of their natural way of life in order to serve as entertainment in zoos and touring shows. As Judge Staffan Widstrand pointed out, ‘It could have been any one of us there in the audience, from anywhere in the world, at pretty much any zoo.’

Since the beginning of 2020, the COVID-19 pandemic has caused tourist enterprises across every continent to grind to a halt, leaving many elephant owners without the income needed to keep the animals. Consequently, many sanctuaries have been overwhelmed with abandoned elephants.

How you can help
-Question the places you visit as a tourist. Are the animals being looked after? Avoid visiting places that make money from exploiting the natural world.
-Talk to your friends and family about their impact as tourists.

-Support initiatives which are helping to protect elephants in their natural habitats.”

“Marine biologist Audun was on an expedition at sea with the Norwegian coastguard when he spotted this floating mass of dead and dying herring. On the horizon bobbed a fishing boat, which had overloaded and burst its nets.

Overfishing – catching fish faster than their populations can recover – is one of the biggest threats to ocean ecosystems. It is estimated that a third of global fish stocks are being exploited at unsustainable levels.”

“Through the long days of a lockdown in 2020, Gagana watched a pair of rose-ringed parakeets raise their young inside a dead tree left standing outside his family home in Colombo. From his balcony Gagana captured the moment three chicks peeked out of their nest.

Rose-ringed parakeets are native to South Asia and parts of central Africa. Feral populations of these bright green birds have also become established in cities around the world, where they may compete with local species for nesting sites.”

“To get this fleeting shot, Jack had to abandon his tripod, grab his camera and run. The result was the highlight of three years’ work observing white-tailed kites. Finally everything had come together perfectly.

Juvenile white-tailed kites must master aerial food exchange from their parents until they can hunt for themselves – typically by hovering, then dropping down to grab small mammals. Later, they need to perform aerial courtship rituals, where a male offers prey to a female.”

“Stefano followed these reindeer during the rutting season. Watching the fight, he felt immersed in ‘the smell, the noise, the fatigue and the pain’. The reindeer clashed antlers until the dominant male (left) chased its rival away, securing the opportunity to breed.

Reindeer are widespread around the Arctic, but this subspecies occurs only in Svalbard. Populations are affected by climate change, where increased rainfall can freeze on the ground, preventing access to plants that would otherwise sit under soft snow”

“Following a storm, it took hours of searching by helicopter to find this fractured sea ice used as a birthing platform by harp seals. ‘It was a pulse of life that took your breath away,’ says Jennifer.

Every autumn, harp seals migrate south from the Arctic to their breeding grounds, delaying births until the sea ice forms. Seals depend on the ice, which means that future population numbers are likely to be affected by climate change”

“Elize heard that an elusive fossa was in the area. Having caught sight of the carnivore, she followed as it wandered into a rubbish dump in search of food. Elize captured the moment it glanced up from foraging, a restaurant bill stuck to its head.

Fossas are found only on the island of Madagascar. Researchers are working to better understand these increasingly rare mammals, which are threatened by the destruction of their forest habitat and by human hunting.”

“For five years Laurent and his team returned to this lagoon, diving day and night to see the annual spawning of camouflage groupers. They were joined after dark by reef sharks hunting the fish.

Spawning happens around the full moon in July, when up to 20,000 fish gather in Fakarava in a narrow southern channel linking the lagoon with the ocean. Overfishing threatens this species, but here the fish are protected within a biosphere reserve.”

“Following a tip-off, Georg photographed these wasps in the early morning, when they are most docile. He approached with a wide angle for maximum impact. ‘I had to move very slowly and wrap up to avoid too many stings,’ Georg recalls.

The wasps’ cluster of hexagonal cells, where the queen lays its eggs, is made from wood pulp mixed with saliva. This colony was started on a wayside traditional shrine decorated with corn cobs in thanks for the harvest.”
