Scientists have successfully filmed two nankeen kestrels hovering in a wind tunnel, revealing how these raptors maintain their heads' fixed position despite turbulent conditions. The research took three years to train the birds and involved 52 reflective markers to create 3D models. The findings show that the birds' morphing wings, wrist movements, and tail adjustments enable them to achieve remarkable stability.
