Factors affecting detection of American woodcock on singing-ground surveys

Duration

September 2007 - December 2011

Narrative

We are assessing factors that influence the reliability and precision of Singing-ground Surveys to estimate American woodcock population trends.

Project Objectives:

1) Estimating detectability of woodcock using current sampling protocols:
repeated (occupancy) sampling of a subsample of routes
assessing detectability based on video or telemetry to refine conditions under which woodcock are detectable
double observer assessment of detectability and observer variability
repeating survey routes to assess detection probability through time
(2) Comparing woodcock density along SGS survey routes with randomly-located experimental routes in adjacent areas to directly assess whether counts on existing routes adequately represent the larger landscape.
