RCSM - totaux quotidiens estimés: Delta Marsh Bird Observatory
À propos
Résumé de l’ensemble de données
Counts from Delta Marsh Bird Observatory (DMBO) 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
At this site, daily from 1 May to first week of June; first week of July through end of September.
Région géographique couverte
Located near Portage la Prairie, Manitoba (50.189, -98.261). Isotope analyses indicate migrants at the site likely originated primarily from breeding range in Manitoba, northern Prairie Provinces and Northwest Territories.
Principales espèces couvertes
Captures were primarily small passerines, but all species observed were 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
For this site: Standardized daily banding (6 hr rom dawn onward, 10 nets), a fixed-route census lasting about an hour, and incidental observation during standard operations.
Méthodes d'analyse
See Quick Links. Historic population trends for all species at this site were based on counts on Daily Estimated Totals
Suggestions
Data from this site are not directly comparable to data from the successor station at Oak Hammock Marsh. Operations manual available (https://www.birdscanada.org/bird-science/cmmn-protocols)
