Johnson’s Mills is an example of a critical stopover for migrating shorebirds. Every summer, massive flocks of shorebirds journey through the Bay of Fundy from the Canadian Arctic before heading to South America. Johnson's Mills becomes the stage for one of nature's great migrations, as its mudflats and beaches serve as a temporary stopover for flocks of shorebirds numbering up to a quarter of a million individual birds

This summer, the shorebirds will still arrive in this special place. However, due to health and safety concerns related to the coronavirus outbreak, we are unable to invite you into the interpretive centre.

As important work still needs to be done, staff and researchers will be onsite at the Johnson’s Mills Shorebird Reserve to make sure that the habitat and birds are protected.

Treading lightly around the shorebirds

Please stay off the beach two hours before to two hours after high tide.

During their short stay, it is imperative that the birds be able to feed and rest undisturbed. Shorebirds can't swim, which makes them vulnerable at high tide when they need to rest on the beach. As a result, we ask that visitors please stay off the beach during high tide.

Shorebirds are easily startled and something as simple as a passerby can scare them into flight, depleting the fat stores they need for their long flight south.

Tips for watching the shorebirds:

  • Keep your distance and stay on the road.
  • Walk softly. 
  • Don't wave or shout.
  • Drive slowly and quietly .
  • Don't litter.
  • Leave your pets at home.

Conservation values

Semipalmated sandpipers are the most common shorebird stopping over at the Upper Bay of Fundy to feed and rest. In just a few weeks, the birds double their weight by eating mud-dwelling invertebrates that are exposed at low tide before leaving for South America.

Other shorebirds you can see include:

  • semipalmated plover
  • least sandpiper
  • sanderlings
  • black-bellied plover
  • white-rumped sandpiper
  • ruddy turnstone

NCC, with the help of Conservation Volunteers, has planted native trees and strategically placed shrubs that will further develop the protected area.

NCC aims to ensure that the shorebirds have a successful respite with minimal stress before making their non-stop 4,300-kilometre flight to South America.

NCC staff will monitor the beach at high tide.

Our vision for Johnson's Mills

NCC is currently responsible for 26 properties here and wishes to secure additional lands at Johnson's Mills. Since 1994, NCC has worked with partners and willing landowners to acquire critical shoreline areas. Stewardship remains a key focus, and NCC is currently raising money for an endowment fund and for future land securement. This fund will provide for the ongoing management of all of the area properties, as well as for the interpretive centre.


The Nature Conservancy of Canada wishes to recognize and thank the New Brunswick Wildlife Trust Fund (NBWTF), the New Brunswick Environmental Trust Fund, Canada Student Jobs, the Jack Iwanicki Fund and donations from the public for its generous and ongoing support of our work at Johnson's Mills. Financial contributions from NBWTF for NCC projects over many years have been instrumental in helping us carry out our conservation and stewardship efforts.
