  • They are strictly nocturnal at breeding sites to avoid predation by gulls and skuas, and will even avoid coming to land on clear moonlit nights.
  • They have an average lifespan of 20 years, the maximum recorded age is 36 years.
  • The Leach's Storm-Petrel was first described in 1818 by Louis Jean Pierre Vieillot, a French ornithologist. It is named for the British zoologist William Elford Leach.
