The Great Lakes Migrant Waterfowl Surveys provide periodic data on waterfowl abundance, spatial and temporal distributions, and use along the shorelines of major water bodies and river systems in Ontario during mostly during spring and fall, and to a lesser extent during summer and winter,...

The Point Lepreau Bird Observatory (PLBO), located in Point Lepreau, New Brunswick, was created as a project of the Saint John Naturalists’ Club (SJNC) in late 1995. The SJNC began accumulating data on bird migration through the Bay of Fundy in spring and fall in 1996. Migration data are...

This data set includes the locations of all known seabird colonies along the coast of British Columbia, and provides a compilation of the population estimates of seabirds breeding at those colonies since 1980, and historical estimates prior to 1980 for some colonies. It does not include an...

We synthesized 19 years of Sage Thrasher occurrence and related habitat data across the species' northern range in British Columbia (BC) and Washington (WA) to define critical habitat characteristics. We combined this field-derived (local-scale) data with GIS-derived (landscape-scale) data into...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Trends in Canada's bird populations indicator reports population trends of Canada's native bird species from 1970 to...

This polygon outlines the basic area included in the survey counts. This area is the best approximation of the mudflat that can be surveyed from shore and is exposed at tide tide height of 3.5 m, based on tidal predictions at Point Atkinson, British Columbia.

This line outlines the basic survey route included in the survey counts. This route is the best access to areas that can be surveyed from shore.

Survey effort is a polygon feature class with the original transects – for reference.

Rare species is a point feature class containing rare species sightings.

Study area is a polygon feature class showing the extent of where most of the bird sightings were recorded and then used in the atlas. A few rare species have been included as well that go beyond this area.
