Atlantic Canada Coastal Waterbird Survey

About

Dataset summary

Long-term data on the abundance and distribution of waterbird species along the Atlantic coastline. Regional programs (NL, NB, NS) brought together under one data platform with aligning protocols.

Season(s) and frequency

Monthly during winter

Geographic area covered

Atlantic coastlines (Newfoundland and Labrador, New Brunswick, Nova Scotia, Prince Edward Island)

Primary species covered

Waterbirds

Goals

The ACCWS has the following specific objectives: to assess the annual changes and long-term trends in population size and distribution of coastal waterbirds in Atlantic Canada, to collect data that contribute to population estimates of coastal waterbird species in Atlantic Canada, and to advance our understanding of the ecology and the effects of human activity on coastal waterbirds in Atlantic Canada.

Methods

Sampling Design

Sites largely picked by coordinators on headlands or accessible sections of coast where waterbird viewing is possible.

Field methods

Observers count all waterbirds, by species, at regular intervals at specific locations so that coordinated information on distribution and migration over a broad area can be acquired. Surveys are conducted as close to high tide as possible, and in the same manner each time.
