RCSM - totaux quotidiens estimés: Rocky Point Bird Observatory
À propos
Résumé de l’ensemble de données
Counts from Rocky Point Bird Observatory for two locations: Rocky Point (RPBO) and Peddar Bay (PEBA), 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 at both sites from July 21st to October 18th.
Région géographique couverte
Located at southern tip of Vancouver Island, BC (Rocky Point: 48.32, -123.59; Pedder Bay: 48.35, -123.57). Migrants at these sites originate primarily from breeding range in British Columbia, 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 at Rocky Point (standardized since 2003) and Peddar Bay (started 2012) include a daily 7 hr count period, with 6 hr of standardized banding (13 nets at Rocky Point; 15 at Pedder Bay), a fixed route census (1.5 hr at Rocky Point; 1.25 hr at Peddar Bay), visible migration counts and other observations
Méthodes d'analyse
See QuickLinks. Population trends for ‘Regular Migrants’ at these sites 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, it had been noted that no data were collected at Rocky Point in 2007
