Field notes

  • They hit the water at speeds up to 100 km/h (60 mph) by streamlining their bodies into an arrow shape during a dive.
  • Specialized subcutaneous air sacs in the face and chest act as airbags to cushion the impact of high-velocity water entry.
  • They lack external nostrils, an evolutionary adaptation that prevents water from being forced into the respiratory tract.
  • Their eyes are positioned forward for binocular vision, allowing them to accurately judge distance to prey from heights of 30 meters.
  • Breeding pairs are typically monogamous and perform elaborate 'sky-pointing' and 'billing' rituals to reinforce pair bonds.
Habitat
Steep coastal cliffs and rocky islands for nesting; pelagic (open ocean) environments for foraging.
Range
North Atlantic, breeding along the coasts of North America and Europe and wintering south to the Gulf of Mexico and Northwest Africa.
