Canadian Migration Monitoring Network
By Request
2004
CMMN was launched in 1998 as an ongoing monitoring program. The first migration monitoring station in North America was LPBO, started in 1960. McGill Bird Observatory was established in 2004, standardized migration monitoring began in 2005.
This dataset contains daily estimated totals (DET) from the McGill Bird Observatory. 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.
Spring monitoring runs from March 28 to June 5 and fall monitoring runs from August 1 to October 30.
Located near Sainte-Anne-de-Bellevue, Quebec (45.430262, -73.939404). The count area is approximately 22 hectares.
Primary focus is landbirds (104 priority species).McGill Bird Observatory also participates in MAPS, nest box banding and winter population monitoring
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. The banding period is 5 hours and the coutn period is 6 hours, including a 1 hour census. The station runs 16 mist nets.
Most stations produce some form of annual report for members.
