Storm petrels are impressive birds, the size of a songbird but with the lifestyle of an albatross! True seabirds, they spend most of their time out at sea and only return to land to breed. Nesting in burrows or rocky crevices, they are vulnerable to predation from mammals like rats, so are usually only found on small, offshore islands where these animals are absent. They sing from their burrows at night, a delightfully bizarre purring sound, mixed with occasional grunts and squeaks.Like other birds in their order (known as tubenoses), storm petrels have an excellent sense of smell, which helps them find food from great distances when flying over the open ocean. There is also evidence that they can recognise other individuals and even choose mates using their sense of smell. They do have a distinctive aroma - storm petrels give off a pleasant, musky scent that makes them a favourite amongst seabird ringers and scientists!
What to look for
A tiny, delicate-looking seabird, not much larger than a house martin, which its plumage slightly resembles. It has dark, brownish-black wings, body and head, with a broad white patch of white on the rump and a short, dark, square-ended tail. There is a distinctive white band on the underside of each wing, which helps separate this species from other similar storm petrels.When seen closely, the small bill has a distinctive ‘tube’ on top, giving it away as a member of the group of seabirds known as tubenoses, which includes albatrosses, shearwaters and the fulmar.
