Satellite tracking of migrating ospreys identifies specific welfare hazards including power lines, hunting pressure, and habitat degradation along established migration routes.
Osprey migration welfare tracking provides welfare-specific conservation intelligence that population counts cannot deliver. Knowing that a specific power line section in Morocco killed three tracked ospreys enables targeted intervention at that location. Understanding that wintering ground drought reduces return migration success in 3-5% of the population connects climate policy to individual osprey welfare outcomes. The tag-to-welfare-outcome chain is short enough that satellite tracking justifies its welfare cost — the welfare information generated by tracking a population enables protection improvements that benefit far more individuals than are tagged.
