Dataset
Daily Migration Counts: Albert Creek Bird Observatory
About
Dataset summary
Counts from Albert Creek Bird Observatory (ACBO) 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
Season(s) and frequency
Spring (April 23rd to June 10th) and fall (July 23rd to September 23rd)
Geographic area covered
Located in southern Yukon Territory (60.06, -128.92). Migrants at the site originate primarily from breeding range in Yukon, Alaska and western Northwest Territories
Primary species covered
Captures are primarily small passerines, but all species observed are recorded
Goals
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
Methods
Sampling Design
Daily capture and observation during migration seasons to generate species-specific daily totals of birds detected within each study site
Field methods
For this site, 7.5 h of standard daily operation (standardized in 2004), including 6 h or banding and incidental observations
Analysis methods
See Quick Links. Population trends for all species at this site are based on Daily Estimated Totals
Advice
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, no alerts had been recorded
