This data was derived from field work conducted in June 2019 where sixty AudioMoth passive acoustic monitors were placed along agricultural field margins in Iowa, USA. Twenty-five of the monitoring location were established by farmer and landowner collaborators, and the remaining (35) sites were established by the author (A.P.D.). Unique vocalizing bird species were counted in ninety-five recordings from 6 to 8 days during dawn hours per site. High resolution mapping identified non-crop vegetation and texture at spatial extents ranging from 100 to 1000 meters. Pesticide and fertilizer application were collected via a survey with collaborators. Site location names are included when the research site was an Iowa State Research and Demonstration Farm (ISRF). When the site was a collaborator, the site name was anonymized to "Collaborator" to respect the privacy of participants.

Column definitions location - recording location Extent_meters - Radial distance in meters (spatial extent) of non-crop vegetation measure VBRICH - Vocalizing bird richness Noncrop_perc - Noncrop vegetation percent within spatial extent Noncrop_m2 - Noncrop vegetation square meters within spatial extent Texture_Dis - Noncrop vegetation dissimilarity texture scaled to between 0 and 1 (unitless) Texture_Var -Noncrop vegetation variance texture scaled to between 0 and 1 (unitless) Pesticide - Whether pesticide was applied in 2019 during or prior to June in field adjacent to recorder. Binary measure of 1 or 0, 1 for yes, 0 for no. Fertilizer - Whether fertilizer was applied in 2019 during or prior to June in field adjacent to recorder. Binary measure of 1 or 0, 1 for yes, 0 for no.
