One morning, this Redditor woke up to his front porch completely riddled with holes. It looked like some gang members spewed buckshot at his doorstep during a drive-by. These holes were made by acorn woodpeckers. The little birds created their own granaries or “acorn trees” to store their food. They do so by drilling holes into whatever they can, sometimes resulting in this kind of damage.

Grand title winner: Environmental photographer of the year. The Bitter Death Of Birds by Mehdi Mohebi Pour. This photo shows the efforts of the environmental forces to collect the bodies and prevent the spread of this disease. The Miankaleh wetland is being destroyed by changes in the climate and it is my duty as a photographer to highlight these problems and create a record for history. I want to prevent the complete destruction of the wetland and the potential environmental disaster by showing the issues and threats to these beautiful natural places.

These are the ambitious plans which suggest skyscrapers of the future may house an entire city. The Endless City project is an award-winning proposal by sure Architecture, who propose turning skyscrapers into complete ecosystems. London is the proposed city for the mixed-use tower – which would feature huge ramps linking different sections of the structure. The company, whose design won the SkyScrapers and SuperSkyScrapers Competition, insist the structure would be a great space-saver in dense cities which have previously spread outwards rather than upwards.

These hyper realistic drawings are so lifelike they could pass for photographs. The incredibly detailed works of art were created by self-taught artist Ivan Hoo, from Singapore, who earns a living from his realistic drawings and paintings. The 31-year-old takes up to three days to complete the impressive pieces, which include animal portraits and still life drawings of everyday items such as a Starbucks cup. The A3 sketches are completed using a range of soft pastel pencils and are drawn from still life, or a photograph taken by Ivan himself. Here: Ivan Hoos drawing of a pug.
