1989
CMMN was launched in 1998 as an ongoing monitoring program. The first migration monitoring station in North America was LPBO, started in 1960. Last Mountain Bird Observatory was established in 1989 and standardized migration monitoring began in 1992.
This dataset contains daily estimated totals (DET) from the Last Mountain 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 May 9th to May 31st. Fall monitoring runs from August 3rd to October 7th.
Located near Imperial, Saskatchewan (51.35084, -105.21725). The count area is approximately 20 hectares.
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. The count period id 6 hours with a 1 hour census period. The station runs 13 mist nets.
Most stations produce some form of annual report for members.
