Wayqecha Peru Bird Community Census Data

Bird species presence/absence for 41 species at 72, 0.8 ha, survey points of radius 50 m, arranged 120 m apart on a 6 by 12 point grid across a grassland–forest ecotone (See publication Fig. 1 and Fig. A1). Species were recorded as present at a survey point if detected by either sight or song. Spatial grid references for survey points are also given. Y coordinates are grid rows and X coordinates grid columns. This enables the calculation of species presence/absence at larger spatial scales by grouping together neighboring survey points (e.g. grouping the data for two neighboring survey points creates a survey area of 1.6 ha). Data are in .csv format. Column headings: Site: 0.8 ha survey point names. X: X coordinate on survey grid. Y: Y coordinate on survey grid. Other columns are species names (genus and species separated by an underscore): 1= species presence, 0 = species absence.
