Canadian Migration Monitoring Network
By Request
1960
CMMN was launched in 1998 as an ongoing monitoring program. The first migration monitoring station in North America was LPBO, started in 1960.
Includes banding information such as specific location, date, time, and effort (number and types of nets, etc.), as well as in-hand measurements of biometrics (e.g., wing length), fat levels, molt.
Spring migration coverage generally runs from 1 April through 10 June. Fall migration coverage typically runs from 15 August through 10 November.
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.
