We don't really need an excuse to feature this adorable photo of twin cubs asleep inside a snow den in Wapusk National Park in Manitoba, Canada. But it just so happens that today is International Polar Bear Day, the perfect day for this shot from the 2007 documentary film 'Earth,' which focuses on wild habitats and creatures across the planet.

Roofs of sod have sheltered mainland Scandinavians through countless winters and summers. But those who migrated from Norway's grass-roof log cabins to this Icelandic tundra in the 9th century found none of the rich timberland of their homeland—just wispy birch forests and grassy fields. To survive the cold, they took the old turf roof concept and built on it, encasing not only the roofs but the walls of their birch-framed homes in layers of living, insulating soil.

These sunshine yellow daffodils appear to have caught the eye of a passing blue tit - and no wonder. Bursting with colour on the banks of rivers and streams, these early bloomers have long been admired as a herald of spring. They are also one of the national emblems of Wales, although it is not entirely clear why.
