Andrew Lee/Wildlife Photographer of the Year
Capturing a family portrait of mum, dad and their eight chicks proved tricky for Andrew Lee -- the burrowing owls never got together to pose as a perfect 10. After many days of waiting, and when dad was out of sight, mum and her brood suddenly turned wide-eyed to glance in his direction -- the first time he had seen them all together.
Andrey Shpatak/Wildlife Photographer of the Year
This Japanese warbonnet was photographed in the north of the Gulf of Oprichnik in the Sea of Japan. These unusual fish lead a territorial lifestyle among the stones and rocks of shallow coastal waters. They use their sharp-edged jaws to snap off sea cucumbers and gastropods.
Andy Parkinson/Wildlife Photographer of the Year
Andy Parkinson spent five weeks watching the mountain hares near Tomatin in the Scottish Highlands, waiting patiently for any movement -- a stretch, a yawn or a shake.
Britta Jaschinski/Wildlife Photographer of the Year
Britta Jaschinski's photographs of items seized at airports and borders across the globe are a quest to understand why some individuals continue to demand wildlife products. This zebra head was confiscated at a border point in the US.
Douglas Gimesy/Wildlife Photographer of the Year
Wildlife rescuer and carer Julie Malherbe takes a call to assist the next animal rescue while looking after three recently orphaned gray-headed flying-foxes.
Emmanuel Rondeau/Wildlife Photographer of the Year
On assignment for WWF UK, Emmanuel Rondeau's brief was to photograph the elusive wildlife of the Bhutanese mountains. Surprised to find a rhododendron at an altitude of 3,500 meters (about 11,500 feet), he installed a camera trap. Returning weeks later, he was amazed to find a head-on picture of a takin.
Frédéric Larrey/Wildlife Photographer of the Year
When this six-month-old snow leopard cub wasn't following its mother and copying her movements, it sought protection among the rocks.

Guillermo Esteves/Wildlife Photographer of the Year
Guillermo Esteves was photographing moose on the side of the road at Antelope Flats in Grand Teton National Park, Wyoming, US, when this large bull took an interest in the furry visitor.
Joseph Dominic Anthony/Wildlife Photographer of the Year
Joseph Dominic Anthony formed the idea for this photograph in 2016 on a visit to Mai Po Nature Reserve in Hong Kong. Taken within the Frontier Closed Area on the Chinese border, strictly timed access rules meant years of studying tide tables and waiting for the perfect weather.
Karine Aigner/Wildlife Photographer of the Year
Located a short ride from the Florida Everglades, US, Marco Island is the largest and only developed land in Florida's Ten Thousand Barrier Islands. This Gulf Coast retreat offers luxury resorts, beautiful beaches, multimillion-dollar neighborhoods and, surprisingly, a thriving community of Florida burrowing owls, in this image captured by Karine Aigner.

Mogens Trolle/Wildlife Photographer of the Year
Of all the different primate species Mogens Trolle has photographed, the mandrill has proved the most difficult to reach, preferring to hide in tropical forests in remote parts of Central Africa. This made the experience of sitting next to this impressive alpha, as he observed his troop above, even more special.
Neil Anderson/Wildlife Photographer of the Year
As the weather grew colder, two Eurasian red squirrels (only one is clearly visible) found comfort and warmth in a box Neil Anderson had put up in one of the pine trees near his home in the Scottish Highlands.
Oliver Richter/Wildlife Photographer of the Year

As urban areas grow, threats to wildlife increase, and Iberian lynx have become a casualty of traffic accidents as they too seek to expand their own territories.
Thomas Peschak/Wildlife Photographer of the Year
Although green sea turtles are classified as endangered, at locations like Little Farmer's Cay in the Bahamas they can be observed with ease.
Wim van den Heever/Wildlife Photographer of the Year
As Wim van den Heever watched this huge male lion lying on top of a large granite rock, a cold wind picked up and blew across the vast open plains of the Serengeti, Tanzania.
