The dataset contains the results of the trials of nest detectability using 25 volunteers as "experimental conspecifics” to estimate the detectability of black kite nests to trespassers. The dataset include the ID of Volunteers; Id of the images; ID of the nest; Distance to the nest (measured in AGL and meters); Position of the UAV when taking the image (zenithal, lateral or approaching snapshots); Decoration of the nests (Decorated (1) vs. non-decorated (0)); Detection of the nest by the volunteer (Detected (1) vs. non-detected (0)); Time to detection (seconds); Detection_pair (coded as 1, if the images from the same position and both treatments were detected in a nest, or 0, in the opposite case) and nest dimensions: lenght, width and opening angles, defined as the three angles of unobstructed view of the sky (see main text for further details)
In this study, we used UAS (Unmanned Aircraft Systems) technology to simulate the aerial perspective of trespassing, flying black kites, and assess whether decorated nests were more conspicuous than undecorated ones to a human observer. To this end, we flew at pre-determined distances from actual nests built by black kites a UAS, equipped with a digital high-resolution camera, and gathered images of the nests with and without an experimentally placed decoration. The images were later standardized using ad hoc prepared software and shown to volunteers through a standardized routine to determine whether detection rate varied according to nest decoration status and distance
