What to look for
- Sea-cliff stick eyrie — Haliaeetus leucocephalus coastal eyrie. Locate the windswept volcanic bluff supporting multi-year eagle eyries
- Sparkling fish-hunting surf line — Plantar spicules & dual-fovea strike zone. Centre the nearshore upwelling channel patrolled via telephoto foveal vision
- Island fox coastal sage hills — Urocyon littoralis trophic balance. Scan the coastal sage scrub where fish-eating bald eagles protect endemic island foxes
