We were watching this juvenile Peregrine from a boat. It was just perched in a tree but, at some point, it saw/heard a Belted Kingfisher at the water's edge (https://www.inaturalist.org/observations/213496581 ). So, it went in pursuit. Fortunately, the Kingfisher was adept enough to evade the attack (and took refuge in a rock cave). This Peregrine then swooped way up on the cliffside and perched in a snag. Soon thereafter, one of its parents brought it a rodent to eat (https://www.inaturalist.org/observations/213496584 ). The last photo was after the two Peregrines made the food exchange.

The parent Peregrine that brought in what appeared to be a rodent for its first year juvenile (https://www.inaturalist.org/observations/213496582 ). I took this photo after they made the food delivery. The parent dropped off the food, the juvenile left, and then the parent flew a circle around our boat, and then flew off to the south and out of sight.

Sitting below a little ways away from two Osprey perched their nest/tree. I couldn't say if this Peregrine had any relation to the other two Peregrines that we saw a few miles to the north.
