Title Wayqecha Peru Bird Community Census Data
Downloaded 27 times
Description 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.

Title Wayqecha Peru Bird Community Functional Traits
Downloaded 20 times
Description Species average bill, tail, wing and tarsus trait values for 41 primarily insectivorous bird species from a cloudforest–grassland ecotone at Wayqecha Biological Station, Peru. Please refer to main text for additional details on trait collection methods. Data are in .csv format. Column headings: Species: Species name. Taxonomy follows Remsen et al. (2011). Bill.nares: Average length of bill (mm) measured from bill tip to anterior edge of nares. Bill.width: Average bill width (mm) measured at anterior edge of nares. Bill.depth: Average bill depth (mm) measured at anterior edge of nares. Wing.length: Average wing length (mm) measured on unflattened wing. Tail.length: Average tail length (mm) measured from the tip of the longest rectrix to the point at which the two central rectrices protrude from the skin. Tarsus.length: Average tarsus length (mm) measured as the distance from the notch at the knee to the third crease at the ankle. Sample.size: Number of individuals measured. Measured.on.Site: Y = measurements taken on individuals captured within the survey site at Wayqecha. N = measurements taken on museum specimens.

Title Wayqecha Peru Bird Community Vegetation Data
Downloaded 18 times
Description Vegetation characteristics within a 20m x 20m square centered on each of the 72, 0.8 ha bird survey points from a cloudforest–grassland ecotone at Wayqecha Biological Station, Peru. Please refer to publication main text for additional details on vegetation data collection methods. 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. Max.canopy.height: Maximum canopy height in meters, estimated by eye. Percentage.grass.cover: Estimated by eye. Percentage.shrub.cover: Estimated by eye. Percentage.tree.cover: Estimated by eye.
