About the Osprey

The Osprey is the fish hawk — a specialist that hunts by hovering high over Michigan lakes, then folding into a feet-first plunge that can take it completely underwater. Every part of the bird is built for it: reversible outer toes, spiny foot pads for gripping, nostrils that clamp shut, and dense oiled plumage. In flight the long, crooked wings show a distinctive M-silhouette.

Like the eagle, Michigan's Ospreys were knocked down hard by DDT and have climbed back — with an assist from artificial nest platforms and a creative program that relocated chicks from northern marshes to jump-start southern Michigan nesting. Watch for the huge stick nests topping channel markers, cell towers, and platform poles.


Diet

Fish

Live fish almost exclusively — bass, perch, bullheads — carried head-first into the wind like torpedoes back to a feeding perch. An Osprey succeeds on roughly one dive in four, remarkable odds in this business.

Questions birders ask

How is an Osprey different from a Bald Eagle?

Ospreys are smaller and white below with a dark eye-stripe, flying on crooked M-shaped wings; eagles are massive, dark-bodied, and flat-winged. Only the Osprey plunges feet-first underwater for fish.

Why do Ospreys nest on cell towers and platforms?

They historically topped dead shoreline trees, which are now scarce — towers and platforms are simply the tallest "snags" available. Michigan groups maintain nest platforms specifically for them.

Do eagles really steal fish from Ospreys?

Regularly. Bald Eagles harass Ospreys in midair until they drop the catch, then snatch it — sometimes before it hits the water. Benjamin Franklin cited exactly this piracy when he argued against the eagle as a national symbol.

When do Ospreys leave Michigan?

Most are gone by the end of November. They return in March, reach their highest numbers from April through October, and thin out steadily through late summer as birds head south.

What do young Ospreys look like?

Juveniles have neat buff-orange edges on the back and wing feathers, giving a scaled appearance, and orange rather than yellow eyes. Young Ospreys stay on the wintering grounds through their second year rather than migrating north.
