Just as the bluebells finish flowering in our woodlands, the rose-red blooms of red campion start to brighten up the woodland floor. Look for this pretty plant in hedges and roadsides, too.

This large shieldbug lives up to its name, bristling with long pale hairs. It's a common sight in parks, hedgerows and woodland edges in much of the UK.

The common cockle is a traditional seaside favourite, both for its white shells often found in the sand and for the yummy snack of cockles doused in malt vinegar.

A common and stocky bird of our rocky coasts, the rock pipit can nearly always be seen close to the sea. It is a bit smaller than a starling.

Look for the pinky-white flowers of the dog-rose in summer, and its bright red rosehips in autumn. It is a scrambling shrub of hedgerows, woodlands and grasslands.

The tiny, brown-and-white sand martin is a common summer visitor to the UK, nesting in colonies on rivers, lakes and flooded gravel pits. It returns to Africa in winter.

The stately grass-of-parnassus displays pretty, white flowers with green stripes. Once widespread, it is now declining as its wetland habitats are disappearing.

One of our most familiar spring flowers, the cowslip brightens up ancient meadows and woodlands with its egg-yolk-yellow, nodding blooms.

As its name suggests, creeping bent runs along the ground before it bends and grows upright. It is a common grass of arable land, waste ground and grasslands.

One of our most common butterflies, the meadow brown can be spotted on grasslands, and in gardens and parks, often in large numbers. There are four subspecies of meadow brown.

In mild years, the spring-flowering primrose can appear as early as December. Look out for its pretty, creamy-yellow flowers in woodlands and grasslands.
