Leach’s Petrel (Oceanodroma leucorhoa)

Image

Petrels are part of the tubenose family of seabirds, which also include the fulmars, albatrosses and shearwaters. These are very small birds that you usually see flying fast by very close to the water's surface where the air currents are strongest. We mostly see them when departing from hafnarfjörður, Keflavík or Grindavík harbours. We don’t see them often because they’re mainly nocturnal. In very strong winds they get blown inshore and in the UK after the gales in November 1952 about 6,700 birds were found injured.
