Common frogs (Rana temporaria) spawning in a moorland pond. The common frog is found throughout Europe. The breeding season begins in March and it hibernates during the winter. Adults migrate to ponds, where males compete for females. Female frogs lay up to 4,000 eggs (known as spawn) at a time, which are fertilised by the male when they are released. Photographed in Cairngorms National Park, Scotland, in April.
