Dataset

CMMN Daily Estimated Totals: Vaseux Lake Bird Observatory

About

Dataset summary

This dataset contains daily estimated totals (DET) from the Vaseux Lake Migration Monitoring Station. DET is a standard protocol used by Canadian Migration Monitoring Network stations to estimate the total number of individuals of each species occurring at a site during migration.

Season(s) and frequency

Fall monitoring occurs between August 1st and October 15.

Geographic area covered

Okanagan Falls, British Columbia (49.308879, -199.546076)

Primary species covered

Primary focus is landbirds (104 priority species) but some stations also monitor waterbirds, raptors.

Goals

To generate counts of migrating birds for use in long-term population monitoring, especially landbird species not monitored by current breeding or winter surveys; To carry out cooperative research projects on the ecology of migrating birds.

Methods

Sampling Design

Standardized captures and observations used to derive daily estimated total throughout migration window.Daily totals are a combination of the numbers from the banding, census and the observations, Numbers are adjusted down to account for birds duplicated on the different survey methods according to the species general observability and consultation with all observers.

Field methods

Combination of standardized daily captures, census, visible migration counts and other observations resulting in a daily estimated total for each species.Count period at Vaseux Lake is 6.5hours long and includes 14 mist nets.

Analysis methods

Most stations produce some form of annual report for members.
