CMMN Daily Estimated Totals: Pelee Island Bird Observatory
About
Dataset summary
This dataset contains daily estimated totals (DET) from the Pelee Island 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.
Season(s) and frequency
Spring migration coverage generally runs from April 1 through June 10 and Fall coverage typically runs from August 1 through November 15.
Geographic area covered
Pelee Island in southern Ontario. Count area is approximately 40 hectares.
Primary species covered
Primary focus is landbirds (104 priority species) but some stations also monitor waterbirds, raptors.
Goals
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. To monitor long-term population trends in migratory songbirds that breed in the boreal forest ecozone and winter in the Neotropics
Methods
Sampling Design
Standardized captures and observations used to derive daily estimated total throughout migration window. Standard monitoring period is 6 hours in length,using 10 mistnetsof 12m length. Census duration is 1.5hours.
Field methods
Combination of standardized daily captures, census, visible migration counts and other observations resulting in a daily estimated total for each species. Non-standardized Northern Saw-whet Owl banding in the fall.
Analysis methods
Most stations produce some form of annual report for members.
