Hilbre Island wildlife through the year
Hilbre sits within an internationally important estuary. Grey seals, wintering waders and migratory birds can be seen throughout the year, but observation must never disturb the animals or their habitat.
Grey seals
Grey seals can be seen in the Dee Estuary throughout the year, with numbers generally higher in summer, although sightings are never guaranteed. The wildlife calendar shows what to look for each month. Watch from a distance with binoculars. Never approach, feed or disturb hauled-out seals.
Birdlife through the seasons
The islands and surrounding foreshores support internationally important waders and seasonal migrants. Oystercatchers, curlew, knot, dunlin and turnstones are among the birds visitors may see. Keep away from feeding and roosting groups, especially in winter. See birdwatching at Hilbre for what to expect by month, and Hilbre rock pools and photography at Hilbre for other ways to enjoy the shore without disturbing it.
Protected estuary
The Hilbre Islands form a Local Nature Reserve within the internationally protected Dee Estuary. The estuary includes SSSI, SPA, SAC and Ramsar designations, whose legal boundaries and protected features are not identical.
Protect the reserve
Stay on established paths, keep away from unstable cliff edges, take all litter home and do not pick plants or collect wildlife. Keep dogs on a short lead and under control so feeding, roosting and ground-nesting birds are not disturbed; see Hilbre Island with dogs. Barbecues and open fires are not allowed.
Plan a responsible visit
Wildlife viewing never overrides tide safety. Check the calculated crossing guidance, weather, local conditions and Dee Lane noticeboard, carry suitable clothing and leave enough time to return without rushing animals, other visitors or difficult terrain.
