  • Conservation status: ICUN Redlist | Least Concern (Global).  Birds of Conservation Concern 4 | Amber (UK)
  • Population Trend: Unknown
  • Threats:  Human activity/disturbance through increases in recreational activities, habitat loss from coastal development, erosion, pollution and predation at nesting sites.

Description: A tiny, delicate-looking seabird, little bigger than a sparrow.

The Storm petrel 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.

Scilly is internationally important for breeding Storm petrels, supporting England's only breeding population.
