About the Northern Gannet#

The northern gannet (Morus bassanus) is a seabird and the largest member of the gannet family, Sulidae. "Gannet" is derived from Old English ganot "strong or masculine", ultimately from the same Old Germanic root as "gander". Morus is derived from Ancient Greek moros, "foolish" due to the lack of fear shown by breeding gannets and boobies allowing them to be easily killed.

Field-craft tips#

  • Plunge dives demand 1/4000 s and wide tracking AF.
  • Bright sand and surf fool meters — dial in exposure manually or with auto-ISO and compensation.
  • Sightings peak in June, July, August and November, which is when you'll have the most chances.

Ethics#

  • The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
  • Stay on trails, respect closures around nests, leks, dens and haul-outs.
  • Avoid playback and baiting in sensitive seasons; never bait predators.
  • Don't share precise locations of rare, nesting or roosting animals publicly.
