Canadian Migration Monitoring Network
By Request
1993
CMMN was launched in 1998 as an ongoing monitoring program. The first migration monitoring station in North America was LPBO, started in 1960. Observatoire d'oiseaux de Tadoussac was established in 1993, standardized monitoring began in 1995.
This dataset contains daily estimated totals (DET) from the Observatoire d'oiseaux de Tadoussac. 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 May 15th to June 5th. Fall monitoring runs from August 24 to November 25.
Located near Tadoussac, Quebec (48.157046, -69.665315).
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. Observatoire d'oiseaux de Tadoussac uses an audio-lure to attract some diurnal migrants in mist nets : American Pipit, Rusty Blackbird, Bohemian Waxwing, Pine Grosbeak and Common Redpoll. The length of the count period is a minimum of 6 hours. The station runs 14 nets in the spring and 8 nets in the fall. Daily Estimated Totals are not used for the fall migration, only visual migration counts, as the fall banding effort isn't standardized.
Most stations produce some form of annual report for members.
