The data map summarizes shorebird and raptor observations recorded as part of the Migratory Shorebird Project, the Pacific Flyway Shorebird Survey, the British Columbia Coastal Waterbird Survey, the Peru Shorebird Atlas and the Chile Shorebird Atlas.

Scaled circles in the map indicate the average number of birds counted at that the sampling unit across all surveys without accounting for variation in the size of sampling units. These data summaries should not be considered a rigorous assessment, but rather general indicators of abundance and distribution of individual species and taxa. Only shorebirds and raptors are always recorded across all survey locations, so data from other taxa should be considered incomplete.
