Canadian Migration Monitoring Network
Open
2000
CMMN was launched in 1998 as an ongoing monitoring program. The first migration monitoring station in North America was LPBO, started in 1960. Haldimand Bird Observatory was established in 2000.
This dataset contains daily estimated totals (DET) from the Haldimand Bird Observatory (Rock Point, Ruthven and Selkirk stations). 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.
In spring, banding and a daily census are done from approximately the third weekend in March to the first weekend in June and, in fall, from the third weekend in July to the first weekend in November.
Located near Dunnville, Ontario (42.852778, -79.56). The count area is approximately 8.8 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 is 6 hours in duration, the station does not run a census. The station runs 20 mist nets.
Most stations produce some form of annual report for members.
