À propos
Résumé de l’ensemble de données
Counts from Beaverhill Bird Observatory (BBO) 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
Daily counts in spring (May 1st to June 10th) and fall (August 1st to October 10). Fall owl monitoring runs September 9th to November 14th
Région géographique couverte
Located near Edmonton, AB (53.38, -112.52). Migrants at the site originate primarily from breeding range in northern Alberta and 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 (standardized since 1990) include daily banding using 12-17 nets (6 hr from dawn onward), a fixed-route census lasting about an hour, and incidental observations
Méthodes d'analyse
See Quick Links. Population trends for all species at this site 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. Habitat at BBO has undergone succession, such that net locations have been regularly shifted to maintain fairly similar netting conditions, mainly in willow edges
