On the National Park coastal foot path:

A short walk through the woods of Cheriton Bottom and Caroline Grove lead to the Eastern Arm of Bosherston Lakes and the magnificant sight of the Eight Arch Bridge. Within a mile or so of here are the dramatic rocky limestone cliffs of Stackpole Head and St Govan’s Head and Pembrokeshire’s world famous coastal footpath. The large colonies of seabirds who nest here in spring and early summer are a spectacular marvel of nature. Some colonies of specific species are of national and international conservation importance (manx shearwater, gannets) and these nesting communities rely on the biodiversity and bio-productivity of the county's inshore waters.

Here is the jewel in the crown of the Pembrokeshire coastline, from Stack Rock (Elegug Stacks, elegug is Welsh for guillemot) a few miles west of St Govan’s Head to Shrinkle Haven, hiding in the shadow of Caldey Island in the east. This is an unrivalled seascape and offers a feast of rare wildlife all year round.

Guillemots - See them from March to the end of July when they come to the cliffs to nest, spending the rest of their life at sea. Dark brown and white, not as black as the similar razorbill, it has a 'bridled' form with a white ring round the eye and stripe behind it. It lives on Fish and crustaceans.

Razorbills - A medium-sized seabird that only comes to shore from March to July to breed. It is black above and white below. It has a thick black beak that is deep and blunt, unlike the thinner bill of the similar guillemot. The future of this species is linked to the health of the marine environment. Fishing nets, pollution and declining fish stocks all threaten the razorbill. It feeds on sandeels, sprats and herrings.

Kittiwakes - A gentle looking, medium-sized coastal gull with a small yellow bill and a dark eye. In flight the black wing tips show no white, unlike other gulls, and look as if they have been 'dipped in ink'. The population is declining in some areas, perhaps due to a shortage of sandeels. After breeding during the spring and summer Kittiwakes move out into the Atlantic where they spend the winter.

Chough - This is a rare all year round bird and often mistaken for a crow. Identified by its red beak and legs it readily displays its mastery of flight above high cliffs with wonderful aerial displays of diving and swooping. Famously found in flocks of 20 or more in autumn and winter in coastal areas of the Stackpole Estate, it feeds on insects and larvae. There are fewer than 500 breeding pairs in Europe, the majority of which nest alone on coastal area rock ledges in Wales and western Ireland.

Fulmars - Almost gull-like, this grey and white seabird is related to the albatrosses. It flies low over the sea on stiff wings, with shallow wingbeats, gliding and banking to show its white underparts then grey upperparts. At breeding sites along the coast it will fly high up the cliff face, riding the updraughts. Fulmars feed in flocks out at sea and defend their nests from intruders by spitting out a foul-smelling oil.

Great Black-Backed Gull - A very large, thickset black-backed gull, with a powerful beak. Adults are blacker than the smaller lesser black-backed gull. It has a heavy flight and can look quite hunched when perched. It will fight off other gulls and chase them to snatch food.
