Wales

Overview

Originally a large shallow lake that has gradually infilled since the last Ice Age, Tregaron or Cors Caron is today the best remaining example of a raised bog in England and Wales. Much of the bog is protected as a National Nature Reserve and it provides opportunities to study the development of raised bogs.

Around 170 bird species have been recorded here and the area is important for wintering waterfowl as well as breeding wetland birds. The habitats within the reserve range from still-growing raised bog in the centre to wet heath around the edges with rough grassland and patches of willow carr.

Birds

Notable Species

Breeding species include Common Teal, Water Rail, Common Snipe, Eurasian Curlew and Common Redshank amongst the wetland birds and Red Grouse, Tree Pipit, Grasshopper Warbler and Whinchat in the drier areas. Common Redstart and Willow Warbler nest in the willow scrub. Red Kite from the relict Welsh population may be seen hunting over the bog and up to 60 may be present in the area in winter.

Passage periods bring waders including Whimbrel and Green Sandpiper. Greenland White-fronted Goose was once a regular wintering species but today there are rare, however, Whooper Swan and Eurasian Wigeon still occur and raptors at this season can include Common Buzzard, Hen Harrier, Eurasian Sparrowhawk and Merlin as well as Red Kite.

Rarities

Rarities are occasionally reported and in recent years have include Purple Heron, Green-winged Teal, Montagu's Harrier and Great Grey Shrike.
