Cemlyn through the Seasons

Spring
Early signs of Spring may include the first Wheatears arriving on Trwyn Cemlyn, the first Manx Shearwaters weaving through the waves out to sea, or the first Sandwich Tern’s call in the Bay - these are all possible from March onwards. Later on, Spring colour on the grassland around the reserve is provided by Spring Squill and Thrift which stud the ground with blues and pinks, and the first sunny spells may tempt out Common Lizards or Adders to bask. By mid-May, a range of birdlife is becoming visible and audible around the reserve, including terns settling on the islands in the lagoon, Whitethroat and Sedge Warbler singing in the scrub and water-margins, Whimbrel foraging along the rocky shore, and other waders like Dunlin and Black-tailed Godwit on the beach or in the lagoon.

Summer
Summer sees activity on the lagoon islands reach fever pitch with the terns and Black-headed Gulls using every hour of daylight to bring food to fast-growing chicks. The sight, sound and smell of this bustling seabird metropolis make up a memorable Cemlyn experience. June and July is the time to see the stands of Sea Kale in full flower, and to spot Yellow Horned Poppy and Sea Campion along the Esgair - Oystercatcher and Ringed Plover are also nesting on the shingle during this period. On the Trwyn, look out for Tormentil and the deep pink flowers of Centaury, as well as the passing colours of butterflies like Small Heath and Common Blue.
Also look out for the red and green leaf-beetle Chrysolina polita on the Dwarf Willow along Trwyn Pencarreg.

Autumn
The tern chicks are usually fledged by mid-August, ready to start the long migration south to their wintering grounds on the coast of Africa, so by early Autumn, the islands seem strangely peaceful. Other wildlife moves in however – flocks of Golden Plover, along with other waders like Lapwing and Curlew can be seen. Big Autumn tides can uncover interesting marine life that usually remains hidden on the lower reaches of the shore, and rough weather at this time brings a range of seabirds passing close to Trwyn Cemlyn – Manx Shearwaters, Gannets, Kittiwakes and Guillemots.

Winter
The lagoon remains an important resource for birds throughout the Winter months – Little Grebe, Shoveler, and Shelduck can regularly be seen, along with the Coot and Wigeon that also graze on the surrounding fields. The Herons that fish the lagoon at Cemlyn through the year are sometimes joined by a Little Egret darting in the shallows for shrimps. Red-breasted Merganser and Great Crested Grebe can often be spotted either in the lagoon or out in the Bay, while on the rocky shore, a keen eye may pick out a Turnstone or Purple Sandpiper foraging close to the water’s edge.
