À propos
Résumé de l’ensemble de données
Counts from Tatlayoko Lake Bird Observatory (TLBO) of birds banded and observed during daily operations; plus a composite Daily Estimated Total (DET): the best estimate for each species of unduplicated number of individuals detected within the official count area during the daily monitoring period
Saison(s) et fréquence
Standardized daily coverage between August 3 and September 28
Région géographique couverte
Located in southern BC (51.65, -124.4). Migrants at the site originate primarily from breeding range in British Columbia, western Northwest Territories, Yukon and Alaska
Principales espèces couvertes
Captures are primarily small passerines, but all species observed are recorded
Objectifs
To conduct standardized daily migration season counts and collect ancillary data on migration ecology for use in long-term biological and population monitoring of Canada’s bird species
Méthodologie
Plan d’échantillonnage
Daily capture and observation during migration seasons to generate species-specific daily totals of birds detected within each study site
Méthodes de terrain
Daily operations include standardized banding using 12 nets (6 hr from dawn onward), a fixed-route census lasting about an hour, and incidental observation during the 6-hr standard operations period.
Méthodes d'analyse
See Quick Links. Population trends for ‘Regular Migrants’ at this site are based on counts from standardized methods alone (numbers banded and recorded on census), while trends for all other species are based on Daily Estimated Totals
Suggestions
Any disruption to standardized operations relevant to appropriate interpretation of analytical results is noted in a regularly-updated section of the station protocol (https://www.birdscanada.org/bird-science/cmmn-protocols). 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 have altered capture rates for some nets
