Fat hen is a persistent 'weed' of fields and gardens, verges and hedgerows. But, like many of our weed species, it is a good food source for birds and insects.

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.

The small heath is the smallest of our brown butterflies and has a fluttering flight. It favours heathlands, as its name suggests, as well as other sunny habitats.

Chinese water deer are easily distinguished from other deer by their strange teddy bear like appearance and the huge canine tusks displayed by the stags.

The melodious song of the nightingale is the most likely sign of this bird being about. Shy and secretive, it sings from dense scrub and woodland, day and night.

An attractive, green-and-yellow bird, the siskin regularly visits birdtables and feeders in gardens. Look for the bright yellow barring on its black wings, and the black crown of the males.

Seabass is a seafood favourite, appearing on menus throughout the UK. But it's in trouble in UK seas, with much of the seabass we eat imported from European fish farms.

Golden banks of common rock-rose make a spectacular sight on our chalk and limestone grasslands in summer. A creeping shrub, it is good for bees, moths and butterflies.
