Wales: Land of the Wild

It's the first day of spring but winter has a sting in its tail as the country is blanketed with snow. As the sun returns, the breeding season finally gets underway.

It is the middle of spring and the brightest time of year in Wales. The race is on to breed, but predators are on the hunt.

It is summer and the country is basking in a heatwave. In this season of extremes, it is time for some of Wales's smaller - and more exotic - wild animals to shine.

Around half of all British breeding goshawks live in Wales, and they are thriving in woodlands across the country. In a forest in the Black Mountains in Monmouthshire, a female goshawk hunts grey squirrels in a walnut grove.
