Combining point counts and autonomous recording units improves avian survey efficacy across elevational gradients on two continents

BC species are coded using four-letter alpha codes (for English common names); https://www.birdpop.org/pages/birdSpeciesCodes.php. Chilean species are coded using six-letter alpha codes (for scientific names). Species included in family-level groupings are listed in Table A1 of the associated manuscript. Habitat is coded as: AL (alpine), SA (subalpine) and UM (upper montane) Method is coded as: PC (human point count observation), ARU (autonomous recording unit) Locations (lat, long) of point count sites are available in the associated file: "PointCountLocations_BC_CH.xlsx" "spp_acc" files contain species precence/absence data formatted for species accumulation curves/Hill number calculations. Note: PC records were further subsetted to only those sites also surveyed by ARUs prior to analysis. "Unmarked" files contain family-level precence/absence data and site and survey-level condition variables for program "Unmarked".
