Dataset
Daily Migration Counts: Brier Island Bird Migration Research Station
About
Dataset summary
Daily banding totals from the Brier Island Bird Migration Research Station (BIBMRS)
Season(s) and frequency
Daily coverage for 3 weeks between 12 August and 12 September
Geographic area covered
Located on Brier Island, southwestern Nova Scotia (44.28, -66.35). Migrants at this site originate largely from breeding range in the Maritime Provinces
Primary species covered
Captures are primarily small passerines
Goals
To conduct standardized daily migration season counts and collect ancillary data on migration ecology for use in long-term biological and population monitoring of Canada’s bird species
Methods
Sampling Design
Daily capture during migration season
Field methods
Daily operations (standardized since 2005) consist of mist netting (17 nets) from sunrise to 1 p.m.
Analysis methods
See QuickLinks. Population trends for all species at this site are based on standardized banding totals
Advice
Any disruption to standardized operations relevant to appropriate interpretation of analytical results is noted in a regularly-updated section of the station protocol (https://www.birdscanada.org/bird-science/cmmn-protocols). As of 2025, it had been noted that the station did not operate in 2020 or 2021 due to covid restrictions
