Satellite tracking of ospreys has transformed understanding of their migration routes and wintering grounds, enabling targeted conservation along routes used by UK breeding birds.
Satellite tags, if improperly fitted, can cause feather damage, reduced flight performance and injury. Modern backpack harness designs minimise this but require proper fitting by trained professionals. Birds tracked reveal welfare hazards including areas of high persecution and ecological traps where fish availability has declined. Tracking data improves conservation targeting that ultimately benefits individual bird welfare.
