Osprey
A fish-hunting hawk that dives feet-first into open water and flies off with its catch turned head-forward like a torpedo.

Eats fish
An osprey hunts almost entirely by sight, circling or hovering 30 to 100 feet over open water until it spots a fish near the surface, then folding its wings and dropping feet first, sometimes going fully underwater for a moment before pushing back into the air.
Should you worry?
None. An osprey hunts fish, not people, and keeps its distance. If you find a nest on a tall snag or channel marker, watch from below rather than climbing toward it.
Every summer, rangers inside Crater Lake’s caldera keep a short list of nesting snags, checking which osprey pair came back to which one. What they’re watching for from the rim is a bird stalled over open water, wings bent at the wrist, head locked on something under the surface. It goes in feet first, vanishes for a second in a ring of spray, and comes up with a fish clamped in its talons, the reason rangers still call it by its old nickname: fish hawk.
Grabbing a fish that is alive, wet, and trying to twist free is the hard part, and an osprey is built for exactly that. It is the only hawk in North America with a reversible outer toe, so it grips with two talons in front and two behind instead of the usual three and one, and the sole of each foot is covered in small backward-pointing spikes called spicules that dig into slick scales. Once it’s airborne again, the bird works the fish around in its feet until the head points forward, the same shape a canoe takes pointed into the current, cutting the drag of every mile back to the nest.
Nearly everything an osprey eats is a fish it caught itself, in a dive like that, over and over, all summer. Watch one stall over open water at a Crater Lake rim overlook, or over the Tule Lake basin near Lava Beds, wings bent, head locked down. The next sound is a hard splash, and the bird that comes up out of it is already turning its catch to face forward for the flight home.
Did you know?
- An osprey can plunge feet first with enough force to go completely underwater for a second before flapping back into the air, fish in its grip.
- Crater Lake's rangers monitor osprey and bald eagle nesting sites inside the caldera every year, watching for returning pairs and new arrivals.
- An osprey almost never eats anything but fish. Nearly its entire diet, day after day, is live fish it catches itself.
Common questions
Are ospreys dangerous to kids?
No. They hunt fish over open water and stay away from people. Watch any nest from a distance and don't try to climb toward it.
How does an osprey catch a fish without losing its grip?
Its feet have a toe that can swing to face backward, so it grips with two talons in front and two behind, and the bottoms of its feet are covered in tiny spikes that dig into a slippery fish.
Why does an osprey carry a fish facing forward?
It shifts the fish in its talons so the head points the direction it's flying, cutting down wind resistance, the same reason a canoe is easier to carry pointed forward than sideways.
What do ospreys eat?
Almost entirely live fish that they catch themselves by diving feet first into water.
Where can you see an osprey at Crater Lake?
Scan the sky above the lake from any rim overlook. A raptor circling and hovering with white underparts and a dark patch at the wrist is likely an osprey.
