We watched him land in the sentinel tree just off the parking area, hovering over the branch then lowering with outstretched talons. Later we saw him flying across the bay – until he did a sudden wing-tip dive/turn, dropped down onto the water, struggled back aloft, and returned toward us, something clearly in his beak. He stayed low to the water until he reached the beach, then soared up to land in the perch tree in the Kala Point copse. Even from a distance we could see him eating, tearing his catch with beak and claws.
This was taken a few minutes later; you can see remnants of the chase on his lower breast feathers.
