Aberystwyth is situated on the coast of Cardigan Bay, between three hills and with a mostly pebbled beach, which extends round to Tanybwlch. There are also a number of rock platforms, including Castle and College Rocks, and a harbour.

As expected with such a wide expanse of coastline there is a wide variety of avifauna, that can be seen around town, on the beaches and further out to sea. Some of these species include:

-

Black backed gulls.

-

Mediterranean gull.

-

Black headed gull.

-

Oystercatcher.

-

Black redstart.

-

Purple sandpiper.

-

Common scoter.

-

Ringed plover.

-

Cormorant.

-

Rock Pipit.

-

Gannet.

-

Starling.

-

Herring gull.

-

Turnstone.

-

Manx shearwater.

-

Whimbrel.

Information on some of the species that can be found is below:

Black redstart:

These can be seen around the Castle. The black redstart only became an established breeding species from the 1940s and since then numbers have increased, however it is still mostly a south eastern species. They are mostly found in towns, where they feed mainly on insects.

The male is characterised by black body plumage, with a white wing panel and red tail, whereas the female has a more grey-brown body plumage, a lot like the young males. The female's colouring is well suited for camouflage when nesting in holes in walls.

It is mostly a late autumn and winter visitor to Aberystwyth.

For more information visit the R.S.P.B website.

Starling:

The starling roost under the pier is one of the only two starling roots on piers in the country. They give one of the most spectacular shows of the autumn in Aberystwyth. Also they have given many students a very interesting research project!

Starlings, a once very common species, have seen a decline in recent years. They can been seen in most habitats, feeding on seeds fruit and insects, and thus are common garden visitors.

They breed in holes in buildings and trees, and where many starling live together, they often synchronise their breeding times. Starlings may appear similar to a blackbird on fist glance, however they have a longer bill in comparison to their body size and their plumage is very glossy with iridescence and small white speckles on their under body. The young are mousy brown with a black bill, whereas the adult bird's bill is a bright yellow.

Most UK starlings remain resident throughout the year.

Manx shearwater:

The Manx shearwater, although not breeding close to Aberystwyth, can been seen off the coast during the summer months and is most likely to be seen in great numbers when offshore. Like other shearwaters, the Manx shearwater is very vulnerable to predators on land and therefore spends most of its time at sea.

It only comes to land to breed where it rears its young in burrows. It feeds on mostly fish and squid. The Manx shearwater are fast flying birds which appear to skim the water as they fly. They have a dark brown to black plumage above and a white one below.

Manx shearwaters are only seen around the UK coast during summer, preferring to spend the winter months in south America, some 5000 miles away!

Gannet:

Gannets are another species of bird primarily only seen out to sea; however from the coastline, occasionally. They are large birds, white with a buff coloured crown and black wing tips.

Young birds take around four years to gain their full adult plumage, until then they have varying degree of grey mottling on their plumage. Gannets breed mainly on rocky islands and eat fish, mainly mackerel, which they can intermittently be seen diving for around Aberystwyth.

Gannets winter around the Bay of Biscay and Morocco.

Rock pipit:

Rock pipits are a generally solitary species found almost exclusively along rocky coasts and salt marshes. They feed on marine animals and insects, as well as seeds.

As the name suggests, rock pipits tend to nest in rock crevices and it is not uncommon for them to have two broods. Their appearance is very similar to a meadow pipit, however they are slightly larger; a meadow pipit weighs around 14g, compared to a rock pipit at 16g. Their upperparts are also darker; a more greenish brown, with darker legs and less well defined breast streaks.

Along the coast of Ceredigion, the rock pipit is a common species, which is resident.
