SHALLOW waters glow in the midday sun off northern Norway, where a mass of Atlantic herring have caught the attention of humpback whales (left) and killer whales (right). That large black splotch isn鈥檛 a sandbank: it鈥檚 a shoal of millions of fish about to be feasted upon.

This photograph was shot using a drone last year off the island of Kval酶ya. It was taken in January, a time of year when Norway sees little sunshine. Indeed, the light is coming from low on the horizon, despite it being midday. 鈥淚t鈥檚 before we get the sun back,鈥 says wildlife photographer Espen Bergersen. That鈥檚 what gives the water its vivid colour.

Bergersen says it was -13掳C on this day. 鈥淲e were planning to go out in the boat, but it was freezing cold,鈥 he says. 鈥淚t was lucky I couldn鈥檛 start my boat, I guess. I decided to go up with my drone and got this photograph.鈥

While operating the drone from a nearby bridge, he noticed whales circling its supports. 鈥淚 haven鈥檛 seen them do that before,鈥 he says.

The herring populations have migrated northward over the past 10 to 15 years, Bergersen says, leaving behind the fjords of southern Norway and providing a new feeding ground for humpback whales. The whales stop by on their way from Svalbard 鈥 an archipelago between the North Pole and mainland Norway 鈥 to the Caribbean, where they spend the winter.
