The Seagulls of Mont Saint-Michel

Three species of gulls have made their home at Mont Saint-Michel. To encourage a good cohabitation between the birds and visitors, Mont Saint-Michel is here to help! This guide will help you get to know them better, adopt the right habits to better understand their presence on the site, and provide you with all the useful contacts.

For a cohabitation without ruffling feathers

Gulls: a protected species

Although their strong presence in urban areas might suggest their numbers are growing, surveys show that gull populations in France have actually been declining since the 1980s. The herring gull, the lesser black-backed gull, and the great black-backed gull are now considered threatened species.

What the law says

As protected species, it is prohibited to capture, move, disturb, destroy, or alter the resting and breeding areas of gulls, as well as their eggs and nests (Article L411-1 of the French Environmental Code).

 Anyone found intentionally disturbing them is liable to prosecution.

Cohabiting with gulls: the right habits

  • Do not feed the gulls
    Gulls settle more easily in urban areas when they have access to food. Feeding them can result in a fine.
  • Remove access to waste
    Keep your rubbish in tightly closed bins. Clear away any litter nearby.
  • Do not intervene
    Avoid any contact with gulls (eggs, chicks, adults), even if they appear injured or in danger. If necessary, contact the town hall or the French Biodiversity Agency (OFB), who will assess the situation.
  • Prevent nest building
    Remove anything from roofs, terraces, and gutters that could be used to build a nest (twigs, vegetation, plastic, etc.).
  • If a nest has been built
    Do not destroy or move it, and do not break the eggs. Doing so may trigger a new laying cycle and extend the nesting period — and it is prohibited by law.
  • Keep your distance and keep pets on a leash
    While incubating eggs or feeding their young, gulls will defend their territory against anyone who comes too close.
  • If young gulls are on the ground
    Do not move or feed them. Even if the parents seem absent, they are still nearby and caring for them.
  • If cohabitation becomes an issue, or a chick appears injured or in difficulty
    Contact the town hall or the French Biodiversity Agency (OFB) to assess the situation before taking any action.
