Site Description
Long Island and Long Island Bay are located in the southeast portion of the southern section of Lake Winnipegosis. The closest major town is Winnipegosis to the west-southwest. Long Island is a very low-lying, grassy island, that is partly rocky and is surrounded by marshes. The island is very close to the east shore and is located within Long Island Bay.
Three species of colonial birds nest on the rocky parts of Long Island. In 1991, 2,324 nests of Double-crested Cormorants were recorded on the island. Herring Gulls (39 nests) and American White Pelican (153 nests) were also censused in the 1991 surveys.

The site has also been noted as significant for molting and migrant diving ducks, in particular Redheads - in October, 1977, over 60,000 were surveyed here, representing more than 10% of the global breeding population of this species.

IBA Criteria
SpeciesT | A | I Links Date Season Number G C N
Redhead 1977 FA 60,000
Waterbirds 1977 FA 60,000
Note: species shown in bold indicate that the maximum number exceeds at least one of the IBA thresholds (sub-regional, regional or global). The site may still not qualify for that level of IBA if the maximum number reflects an exceptional or historical occurrence.
Conservation Issues
The primary use for Long Island Bay and Long Island is commercial and recreational fishing and hunting. Therefore, the main potential threat to this site is the over-harvesting of fish as all three nesting species mentioned above rely on fish for feeding themselves and their chicks. This site is crown land.

The IBA Program is an international conservation initiative coordinated by BirdLife International. The Canadian co-partners for the IBA Program are Birds Canada and Nature Canada.
