British Columbia Marbled Murrelet Occupied Detection Surveys: Digital dataset
Listed in NASA Earthdata CMR
This data set contains the most complete known Marbled Murrelet occupancy detections at inland stations at georeferenced locations throughout British Columbia.
Description
Detection information includes total number of detections, total number of audio, visual, audio and visual, and total occupied detections. When more than one survey took place at a particular station, the survey information is summed for a total detection.
Summation can occur within years, or across years. The number of surveys conducted, and the years the surveys took place will be noted when available. This database is a compilation of many sources and occupied detection is in some cases defined by the original scientists.

Otherwise protocol is set by the Pacific Seabird Group (2000) as 1) Birds flying below canopy, through, into, or out of forest canopy, 2) Birds perching, landing, or attempting to land, or 3) Birds calling from a stationary position. A call is stationary when more than 3 calls are heard.
