A hedgehog is any of the spiny mammals of the subfamily Erinaceinae, in the order Erinaceomorpha. There are seventeen species of hedgehog in five genera, found through parts of Europe, Asia, Africa and New Zealand (by introduction). There are no hedgehogs native to Australia, and no living species native to the Americas. Hedgehogs share distant ancestry with shrews (family Soricidae), with gymnures possibly being the intermediate link, and have changed little over the last 15 million years.^[2] Like many of the first mammals, they have adapted to a nocturnal way of life.^[3] Hedgehogs' spiny protection resembles that of the unrelated rodent porcupines and monotreme echidnas.

 Coal tit Not as colourful as some of its relatives, the coal tit has a distinctive grey back, black cap, and white patch at the back of its neck. Its smaller, more slender bill than blue or great tits means it can feed more successfully in conifers. A regular visitor to most peanut feeders, they will take and store food for eating later. In winter they join with other tits to form flocks which roam through woodlands and gardens in search of food.

 Blue tit A colourful mix of blue, yellow, white and green makes the blue tit one of our most attractive and most recognisable garden visitors. In winter, family flocks join up with other tits as they search for food. A garden with four or five blue tits at a feeder at any one time may be feeding 20 or more.

House Sparrow

Noisy and gregarious, these cheerful exploiters of man's rubbish and wastefulness, have managed to colonise most of the world. The ultimate avian opportunist perhaps. Monitoring suggests a severe decline in the UK house sparrow population, recently estimated as dropping by 71 per cent between 1977 and 2008 with substantial declines in both rural and urban populations. Whilst the decline in England continues, Breeding Bird Survey data indicate recent population increases in Scotland, Wales and Northern Ireland.

Long eared Owl

 Long eared owl  The long-eared owl is medium-sized owl, smaller in size than a woodpigeon. It often looks long and thin, with head feathers (known as ear tufts even though they are not ears) which it raises when alarmed. It is buff-brown with darker brown streaks, and deep orange eyes. It breeds thinly across the UK with fewer birds in the south-west and Wales. Northern birds migrate southwards, including birds from Europe coming to spend the winter in the UK, while southern birds are residents and only move short distances to find food.

The chaffinch is the UK's second commonest breeding bird, and is arguably the most colourful of the UK's finches. Its patterned plumage helps it to blend in when feeding on the ground and it becomes most obvious when it flies, revealing a flash of white on the wings and white outer tail feathers. It does not feed openly on bird feeders - it prefers to hop about under the bird table or under the hedge. You'll usually hear chaffinches before you see them, with their loud song and varied calls.

Tal-y-llyn Lake, also known as Talyllyn Lake, Llyn Mwyngil or Llyn Myngul is a large glacial ribbon lake formed by a post-glacial massive landslip damming up the lake within the glaciated valley.^[2] It is situated at the foot of Cadair Idris, in the Snowdonia mountain range of Gwynedd, Wales.

Common sandpiper A smallish wader with contrasting brown upperparts and white underparts. It habitually bobs up and down, known as 'teetering', and has a distinctive flight with stiff, bowed wings. Its presence is often betayed by its three-note call which it gives as it flies off.
