Jeffries and other Nature-lovers have written on the marvellous 

 powers of hovering possessed by these birds. In fact, the Kestrel

The Osprey is another example of bad naming. The word is 

 said to be a corruption of Ossifrage, the "bone-breaker." As It 

 feeds on fish, it has no big bones to break. It is spread from 

 "Alaska to Brazil, Lapland to Natal, Japan to Tasmania, and 

 even out to the Pacific Isles," and it may be the same bird 

 throughout, though Dr. Sharpe has allowed three species in the 

 "Handlist of Birds." "The A.O.U. Check-list of North American 

 Birds, 1910," however, recognizes the North American bird as a 

 sub-species only, so it is possible the Australian bird will be also
