March to September


The sandwich tern is a relatively large tern, which breeds in colonies on sand and shingle beaches, islands and spits. Sandwich terns feed on fish, such as sandeels, sprats and whiting, which they catch by diving into the water.

Sut i'w hadnabod

The sandwich tern is whitish-grey above and white below, with a large black cap (the forehead becomes white in winter) and a shaggy, black crest. It has short, black legs, and a black bill with a yellow tip. It has a short tail without 'streamers' (long feathers extending past the main tail).

In our area

Cemlyn Nature Reserve hosts the only colony of Sandwich terns in Wales.  However, without 24/7 protection during the breeding season, there is every chance that the colony will fail.  We need £30,000 to continue to provide wardens for Cemlyn for 2020 and 2021.

Sut y gall bobl helpu

Many of the important sandwich tern colonies in the UK survive because they are on nature reserves specifically looked after for their wildlife value. The Wildlife Trusts manage many coastal nature reserves for the benefit of the wildlife they support. You can help by supporting your local Trust and becoming a member; you'll find out about exciting wildlife news, events on your doorstep and volunteering opportunities, and will be helping local wildlife along the way.
