Machias Seal Island Migratory Bird Sanctuary
The Machias Seal Island Migratory Bird Sanctuary (MBS) is located in southwestern New Brunswick in the Bay of Fundy.
Importance of the sanctuary: migratory birds and other wildlife
Machias Seal Island Migratory Bird Sanctuary is a tiny, treeless oceanic island rising barely 9 metres above sea level. It is located 20 kilometres off the southwestern tip of Grand Manan Island in the Bay of Fundy. Many seabirds nest here.
This small island is one of the most important seabird nesting colonies in the Gulf of Maine. At one time the most numerous birds on the island were arctic and common terns. However, the number of birds nesting here has declined due to, among other factors, the reduced availability of food around the island.
Machias Seal Island is also the home to one of the most southerly colonies of the atlantic puffin (well over 1000 pairs), whose breeding range extends north all the way to Greenland. The other member of the auk family that nests on Machias Seal Island is the razorbill. It is larger than the atlantic puffin, with immaculate black and white plumage and a distinctive white ring around its bill. Approximately 100 pairs of razorbill nest on the island. The leach’s storm petrel also breeds on this island although visitors rarely see this bird as it spends most of its time foraging at sea or hiding in its nesting burrows.
Did you know?
A pair of breeding razorbills will only produce a single egg each year. Once the puffling is about 18 – 20 days old, its father will accompany it on its first adventure at sea.
In addition to these seabirds, a few land birds, including the savannah sparrow, spotted sandpiper, tree swallow and barn swallow, nest on Machias Seal Island. With well over 100 species spotted, the list of migratory birds and incidental visitors found in this sanctuary is extremely impressive and includes several uncommon and rare species.
Landscape
This small, teardrop-shaped island is roughly 550 metres long and 250 metres wide with lush green meadow covering the higher areas and providing a striking contrast to the rocky, wave-battered shores. Machias Seal Island once posed a serious hazard to ships until a permanent lighthouse was built in 1832; this manned lighthouse is still in operation today.
