A Dundee photographer has scooped one of the main awards in the British Wildlife Photographer of the Year competition.
Tomasz Garbacz came up trumps in the “British Seasons” category thanks to his ptarmigan submission.
Meanwhile, an image of a dolphin surfing in the waves claimed top prize in the prestigious contest.
The dolphin’s eye view shot was captured off the coast of Northern Ireland by George Karbus, from County Clare, Ireland, who swam in the surf with the mammal to get the winning image and secure the £5,000 prize.
Mr Karbus said: “Each time the dolphin got into the wave, I dived underneath, held my breath and waited for the moment when he would swish through a silver barrel close enough to my lens.
“Water visibility is always very limited in Ireland and I was very lucky to get a shot like this.”
Striking images of a badger among trees, a fallow deer on a housing estate, a grey wagtail fighting its reflection in a car wing mirror and close-ups of woodland fungus and a tiny snail on a fern were among the winners in the competition.
The judges selected winners for 12 categories which aim to highlight the wealth of nature in the UK, including a wildlife video and a documentary series of pictures which was won with a photo essay on vaccinating badgers for TB as an alternative to culling.
Mr Karbus’s dolphin picture won the coast and marine category and also scooped the prize of overall winner.
Prizes were also awarded for two junior categories, with eight-year-old Liam Constantine, from Hull, East Yorkshire, winning the award for a photograph by a youngster under 12, for his picture of a brown hare.
Joseph Amess, 15, from Steyning, West Sussex, scooped the award in the 12-18-year-olds category for his image of a great tit in flight.
Chris Packham, naturalist and TV presenter, said: “These stunning images by so many talented photographers highlight the diversity, breadth and beauty of our precious wildlife and the need to protect their habitats.
A book showcasing the best of this year’s entries is also being published, and an exhibition of 100 images and video launches at the Mall Galleries in London before touring the country.
