Isles of Scilly Wildlife Trust Gugh, brown rat ("Rattus norvegicus") free, to help breeding sea birds, which lost 25% of their populations between 1983 and 2006. The rats eat eggs and kill the chicks of those birds that nest in burrows or on the ground.

WMIL will return to the islands to do a final check for rats in 2016. In 2014 Manx shearwater ("Puffinus puffinus") bred
Chagos Marine Protected Area Chagos are considered to be of international importance. The archipelago harbours eighteen different species of breeding birds and ten of its islands have been designated as Important Bird Areas (IBAs) by Birdlife International, making the region the most diverse breeding seabird community in this tropical region, though the presence of human-introduced rats on several of the other islands severely hinder seabird nesting on these. Five species are considered to be breeding in internationally significant numbers: the sooty tern ("Sterna fuscata"); the brown and lesser noddy ("Anous stolidus" and "Anous tenuirostris"); the red-footed booby ("Sula sula") and the wedge-tailed shearwater ("Puffinus
