From: The impact of shape and attachment position of biologging devices in Northern Bald Ibises
Migrating juvenile Northern Bald Ibis equipped with a biologging device (A) attached by a wing-loop harness on the upper back and (B) attached by a leg-loop harness on the lower back. At the upper-back position, feathers behind the device constantly flapped due to air turbulence caused by the separation of the boundary layer over the posterior upper part of the body. At the lower back position, the feathers lie more smoothly on the body and show no signs of major turbulence. Images courtesy of Waldrappteam Conservation & Research (www.waldrappteam.at)
