Movement trajectories in the synchronicity of ten Cory’s shearwater Calonectris borealis fledglings tracked with GPS-GSM devices. Ring refers to the unique ring codes of the birds. The animation shows the irradiance values (nW/cm2/sr), as a proxy of light pollution (bluish), taken from a cloud-free composite of VIIRS nighttime lights corresponding to November 2019. Animations were built with the package moveVis of the R statistical software ( Schwalb-Willmann et al., 2020) and they are part of Rodríguez et al. (2022) study.
