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.

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.

This dashing diving duck is a winter visitor to the UK's seas, coastal lakes and occasionally inland water bodies.

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.

Creeping buttercup is our most familiar buttercup - the buttery-yellow flowers are like little drops of sunshine peppering garden lawns, parks, woods and fields.

One of the earliest moths to emerge each year, spending the winter as a pupa and flying from March to May.

Found around our coasts during the breeding season, the little tern is a diminutive seabird. Despite its size, it performs remarkable aerial courtship displays.

Our smallest breeding seabird, the storm petrel is barely larger than a house martin! They mostly nest among rocks or in burrows on small offshore islands.

This elegant wader is an uncommon autumn visitor, often joining flocks of dunlin.
