Red squirrels are native to the UK but are a lot rarer than their grey cousins. They live in a few special places across the UK thanks to reintroduction projects.

This stocky wader is mostly a winter visitor to the UK, where it can be found on rocky, seaweed-covered coasts, often with groups of turnstones.

The waxwing is a colourful winter visitor. It can often be spotted in large flocks in berry-laden bushes in towns, car parks and gardens.

The common octopus is a highly intelligent, active predator. It even has a secret weapon - special glands produce a venom that it uses to incapacitate its prey!

The papery, translucent, silver 'coins' of Honesty are instantly recognisable. They are actually the leftover seed pods that dangle from the plant through winter.

A climbing plant of hedgerows and woodlands, White bryony produces greenish flowers in summer and red, shiny berries in winter. It is a poisonous plant.

Found in compost heaps and under stones in gardens, the flat-backed millipede is a common minibeast. It is an important recycler of nutrients, feeding on decaying matter.

A breeding bird of fast-flowing, upland rivers, the grey wagtail can also be seen in lowland areas, farmyards and even towns in winter.

A much-loved garden bird, the blackbird is famous for its harmonious song. In winter, our resident birds are joined by migrants from Scandinavia and the Baltics.

A pretty, little gull, the kittiwake can be spotted nesting in colonies on clifftops and rock ledges around the UK's coast. It spends the winter out at sea.

These winter visitors are close relatives of the chaffinch and can often be found in the same flocks, where their white rump and nasal calls give them away.
