Résumé de l’ensemble de données
This dataset contains daily estimated totals (DET) from the Tatlayoko Lake 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.
Saison(s) et fréquence
Fall Monitoring occurs in August and September.
Région géographique couverte
Williams Lake, British Columbia (51.653331, -124.404565)
Principales espèces couvertes
Primary focus is landbirds (104 priority species) with some Northern Saw-whet Owl banding.
Objectifs
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. The Goal of Tatlayoko Lake Bird Banding Station is to monitor the health of migratory birds moving through NCC properties.
Méthodologie
Plan d’échantillonnage
Standardized captures and observations used to derive daily estimated total throughout migration window.
Méthodes de terrain
Combination of standardized daily captures, census, visible migration counts and other observations resulting in a daily estimated total for each species. Monitoring period is 6 hours in length and census is 1.25hours. The station runs 12 standard mistnets, 3 non-standard nets and 3 hawk nets.
Méthodes d'analyse
Most stations produce some form of annual report for members.
Suggestions
Any disruption to standardized operations relevant to appropriate interpretation of analytical results is noted in a regularly-updated section of the station protocol. As of 2025, the following alert had been recorded. Note that the portion of count area covered during incidental observations was expanded in 2017, causing noticeable increase in Estimated Totals for certain species, especially grassland birds. As well, regeneration and succession has altered capture rates for some nets.
