Frogbit
Frogbit looks like a mini water-lily as it floats on the surface of ponds, lakes and still waterways. It offers shelter to tadpoles, fish and dragonfly larve.
Fulmar
Related to the massive albatross, the fulmar is a gull-like bird that nests on rocky cliff edges. Don't get too close, though - it spits a foul-smelling oil at intruders.
Gadwall
The gadwall is a dabbling duck, feeding at the surface of shallow water by 'upending' - putting its head down and its bottom up! Only a small number of gadwall nest in the UK, but large numbers winter here.
Garden bumblebee
Unsurprisingly, the garden bumblebee can be found in the garden, buzzing around flowers like foxgloves, cowslips and red clover. It is quite a large, scruffy-looking bee, with a white tail. It nests in colonies.
Garden spider
Have you ever stopped to look at the shape of a spider web? Garden spiders spin a spiral shaped web, perfect for catching lots of juicy prey!
Garden tiger moth
The garden tiger is an attractive, brown-and-white moth of sand dunes, woodland edges, meadows and hedgerows; it will also visit gardens. In decline, it is suffering from the 'tidying up' of our countryside.
Garden warbler
A plain-looking warbler, the garden warbler is a summer visitor to the UK. It is a shy bird and is most likely to be heard, rather than seen, in woodland and scrub habitats.
Garganey
This scarce breeding duck is a summer visitor, spending the winter in Africa. Although large flocks can be found in their wintering grounds, they are usually only seen in pairs or small groups in the UK.
Garlic mustard
Favouring shady spots in woodlands and hedgerows, Garlic mustard can grow very tall. It has small, white flowers and, as its name suggests, smells faintly of garlic.
Gatekeeper
The gatekeeper is on the wing in summer on grasslands, in woodlands and along hedgerows. Look out for the large, distinctive eyespot with two 'pupils' on each forewing.
Germander speedwell
A good luck charm for travellers, Germander speedwell can be seen along roadsides, grassy lanes and hedgerows. Look for clumps of bright blue flowers.
Giant goby
One of the UK’s rarest marine species, this giant of the rocky shore is a very special fish.
