Project name: Atlantic Canada Nocturnal Owl Survey

Goals : The goals of this survey are to determine population trends of owls (especially Barred Owls) in Atlantic Canada, to gather location information on rare or little-known owl species (especially Boreal and Long-eared Owls), and to involve volunteer birders from across the region in active wildlife monitoring.

Dataset summary : The dataset consists of detections of noturnal owls along survey routes with stops established at 2km intervals along roadside.

Status : Active

Year started : 2001

Season(s) and frequency : any evening between April 1 and May 15

Frequency : Annually

Geographic area covered : Maritime provinces of Canada

Type(s) of habitat : Mostly forest and forest-agricultural mix

Primary species covered : Focal species is Barred Owl, also of interest are Northern Saw-whet, Great-Horned, Boreal and Long-eared Owls.

Sampling Design : Randomly selected routes

Field methods : Similar to other roadside surveys using tape playback. Two volunteers drive pre-determined route, stopping at fixed intervals (2 km apart in NB and PE, 1.6 km apart in NS) along roadside. At each stop, 2 minutes of silent listenting is followed by playbacks consisting of pre-recorded owl

Data format : MS Access database

Sample size : 104 routes in 2001

Results : Annual reports written and posted on BSC website (http://www.bsc-eoc.org/regional/nbowls.html)
