As the only crow with a red bill and red legs, the all-black chough is easy to identify. But it's harder to spot: there are only small, coastal populations in Scotland, Ireland, Wales, Cornwall and the Isle of Man.
The streamlined red-breasted merganser is a handsome bird and a great fisher - its long, serrated bill helps it to catch and hold its slippery fish prey. It is most commonly spotted around the coast in winter.
The Red-eyed damselfly is a small, but robust, damselfly of canals, ponds, lakes and slow-flowing rivers. As its name suggests, it has bright blood-red eyes, but a mostly black body.
A bright red beetle, with black legs and knobbly antennae, the red-headed cardinal beetle lives up to its name. Look for it in woodland, along hedgerows and in parks and gardens over summer.
A plump gamebird, the red-legged partridge is an introduced species that seems to have settled here with little problem. It can be spotted in its favoured open scrub and farmland habitats.
The red-throated diver lives up to its name - the distinctive red patch on its throat heralds the breeding season. In summer, it nests in Scotland, but look out for it around the UK's coast during winter.
