Canadian Migration Monitoring Network
Visualizations only
1989
CMMN was launched in 1998 as an ongoing monitoring program. The first migration monitoring station in North America was LPBO, started in 1960.
This dataset contains daily estimated totals (DET) from the St. Andrews Bird Banding Station. DET is a standard protocol used by Canadian Migration Monitoring Network stations to estimate the total number of individuals of each species occurring at a site during migration.
Daily coverage since 2001 from end August to end October; reduced in 2022 to 21 Sept. to 23 October.
From Newfoundland to British Columbia; Member stations in NS, QC, ON (6), MI, MB, SK, AB (3), and BC (2). Pilot stations in NF, PEI, NB, ON, BC and YK.
Primary focus is landbirds (104 priority species) but some stations also monitor waterbirds, raptors.
To generate counts of migrating birds for use in long-term population monitoring, especially landbird species not monitored by current breeding or winter surveys; To carry out cooperative research projects on the ecology of migrating birds.
Standardized captures and observations used to derive daily estimated total throughout migration window.
Combination of standardized daily captures, census, visible migration counts and other observations resulting in a daily estimated total for each species.
Most stations produce some form of annual report for members.
Any disruption to standardized operations relevant to appropriate interpretation of analytical results is noted in a regularly-updated section of the station protocol. As of 2025, no alerts had been recorded.
