This dataset contains daily estimated totals (DET) from the Whitefish Point 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.
At Point: daily in fall, 1 Aug to mid-Nov in most years. Spring coverage in 1999 only (15 Mar-31 May). At Vermillion: daily in spring (mixed start dates but usually mid-May to end June (1993 and 1996-1998). Fall coverage (1996-1998 only) daily from 1 Aug to end Sep.
From Newfoundland to British Columbia; Member stations in NS, QC, ON (6), MI, MB, SK, AB (3), and BC (2). Pilot stations in NF, PEI, NB, ON, BC and YK.
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.
Most stations produce some form of annual report for members.
Any disruption to standardized operations relevant to appropriate interpretation of analytical results is noted in a regularly-updated section of the station protocol. Participation in the Canadian Migration Monitoring Network was aimed particularly at tracking passerines in spring, when birds concentrate on this northward-pointing peninsula. The project ended when it became clear that early spring weather conditions precluded regular coverage. No formal operations protocol for this project are on file to document daily operations, census route, net locations, or daily effort levels. However, experienced CMMN personnel helped set things up and visited periodically, so it is likely that procedures were similar to those documented in the written protocols of member stations in Canada.
