The great osprey seldom crosses the bay without a challenge from its stealthy foe, the white-belly. The voices of both are alike in their dissonance though different in quality and tone, and the smaller bird is invariably the aggressor. This is how they fight, or rather engage in a vulgar brawl which has in it a smack of tragedy. The osprey, with steady beat of outstretched wing, flies "squaking" from its agile enemy, who endeavours to alight on the osprey's back. Just as white-belly stretches its talons for a grip among the osprey's feathers, the osprey turns--and turns without a tremor in its long, sweeping wings--to shake hands with white-belly. For a moment the huge bird rests on its back, silhouetted against the luminous sky, to interlock talons with its nimble foe. But white-belly is fully alive to the risk of getting "into hoults" with so heavy a weight, for on the instant it swoops up with a harsh cry of rage or disappointment. With but a single flap and no quiver of wing the osprey rights itself and sails away (a methodic, unflurried flight) with fleeter white-belly in pursuit, which when within striking distance swoops again, to be faced by the grim, outstretched talons of the osprey, who has turned in flight with machine-like precision. So swift and sudden is the discreet upward swoop of the white-belly that it almost appears to be a rebound after contact with the bigger bird. So the scrimmage, or, to be exact, screamage, proceeds, for each party to it tells the whole Island of its valour, and business stands still as the series of most graceful, yet savage, aerial evolutions is repeated until the rivals are blotted out by distance. Once I saw a bunch of feathers fly from the osprey's back. The aerial capsize had not been timed with accustomed accuracy. Weight told, and it speedily shook itself free; but I am waiting for the day when, in mid-air, the osprey and the white-bellied sea-eagle shall clasp hands. It will be an exciting moment for the sea-eagle. The osprey is a cuter as well as a heavier bird, and, in the phrase of the blacks, "That fella carn let go!" When the osprey comes skirting the hollows of the hills for cockatoos, its hunger will be unsatisfied until, by elaborate and disdainful manoeuvres, the cockatoos are induced to take flight. Perched on the top of a tree, they may jeer in safety as long as they like; but let the flock fly into the open and the osprey will be surprised if it does not get one, and that which is singled out it follows "like a grim murderer still steady to his purpose." Now is the time for this, greatest of the three fishers, to, wax fat and become pompous, for its diet is to be varied with nutmeg pigeons, and the pigeons have come in their thousands and tens of thousands, and if the eaglets do lack and suffer hunger, it will be on account of the laziness of their parents.
