Sampling comments: "From the beginning of July 2015 to the end of June 2016, 10 trail cameras (brands: Bushnell, Stealth Cam, Tasco) were placed along the 20 km stretch of studied railway, one every 2 km, attached to rail-side trees and directly facing the railway... regardless of the number of animals in an image, one photo was considered a single capture event... all capture events recorded within one hour from the initial capture were omitted from the data set"
trap days are not reported, but the study lasted almost exactly one year and the data were divided into four seasons, so there were about 91 days of sampling per season
birds are listed but usable counts are not provided
