Searching, ready, waiting 10:51 AM. (3370)
The osprey – a.k.a. the sea hawk, fish hawk, and river hawk – is an aerial angler that glides high over shallow waters targeting unsuspecting fish. This lean, rapacious raptor hunts . . . prowling . . . circling . . . a bandit’s dark mask stretched around golden eyes staring down from 30 to 130 feet above the water searching for prey. Ospreys have extraordinary vision seeing through reflection and glare on the water’s surface to zero-in on a fish below. Their wide wingspan can extend to six feet, wings offering a fine display of feathers and finishing at the tips with four long, lithe feathers, widely splayed and finger-like, moving through air with grace and flair. The osprey flies with power and ease, maneuvering with an artistry of rhythm, a geometry reborn.
As the osprey soars and scans, it may pause, hover, flapping its wings as if treading air, making sure, waiting for the right moment to dive bold and hard, head first, wings adjusting, plummeting at speeds clocked at 50 mph. At the last moment, just before striking, the osprey extends its long legs and fierce talons, either skimming the water to scoop or plunging hard to grasp its slippery prey. The osprey is equipped with lethal feet, barbed and biting - the inside of each covered with tiny needle-like spicules; and the four long and scaly toes terminating in talons long and dark, curved and sharp. A reversible outer toe that swivels to the rear gives each claw two grasping talons in front and two behind - the perfect tools to clamp a lethal lock onto a slippery fish.
When the osprey hits the water and the grab is made, it’s time to become airborne again. The osprey is light – on average only 3 to 4.5 pounds - and he or she may seize a sizable fish, wriggling, trying to head down and deep to get away. Tremendous strength and exertion are often needed to get up and away with the prize. The oily coating on its wings makes shedding water easier, and the osprey’s powerful wings will arch or kink to form an M, allowing a technique for lifting itself and its captive from immersion.
Once the osprey clears the water, it carries its catch – fish head facing forward - back to its nest or perch. The osprey’s beak is hooked and sharp, appropriately bladelike for slicing or ripping into fish. Usually the osprey will eat the head of the fish first. At the nest, osprey parents will eat and tear the fish into small pieces for their chicks to eat – such feeding will continue until the young are able to hunt and survive on their own.
But the osprey’s hunt for fish is a battle not always won. Sometimes an eagle will play the pirate, bullying or attacking an osprey, forcing it to drop its catch. A clever eagle may even snag the dropped booty in mid-air. An osprey may also release a fish if it is too heavy or aggressive for the osprey to become airborne. Sometimes, an osprey’s talons will hook and get stuck in its victim, and if the fish is strong and heavy, if the osprey becomes fatigued and is unable to release its catch, predator and prey may sink – a fatal encounter for both.
The osprey is joy to watch - its hunter’s instincts and tactics, aerial acrobatics, and ability to plunge into the sea and then elevate with a struggling captive. I have seen an osprey dive into a frenzy of fish and rise out of the melee with a fish in each claw. I wondered how the osprey might feel at such moment - if beneath the fierce look in his golden eye, he might feel a special thrill – the way a golfer does in hitting a hole-in-one or the way a kid might feel standing with an ice cream cone in each hand.
