Avian point count data from riparian corridors of protected areas in Marin County California

The data set is a simplified version of avian point count data collected
in Marin County, CA, USA between 1997 and 2019. Point count surveys (5
minutes) were conducted twice during the breeding season (May and June)
along transects in riparian corridors within protected areas (Point Reyes
National Seashore, Golden Gate National Recreation Area, Mount Tamalpais
State Park, and Bolinas Lagoon Open Space Preserve). Data were collected
by Point Blue Conservation Science biologists and were integrated into the
National Park Service Inventory and Monitoring Program. All individuals
detected at any distance were recorded during the surveys, but this
simplified data set only includes the observations analyzed for this
publication, specifically detections (aurally and visually) within 50
meters of each point count station for each of the fourteen species
selected for analysis.
