220 BIRDS OF ONTARIO, 



fish, the Caracaras would attack them until they disgorged, and then 

 alight and devour the stolen prey. These attacks were made from 

 above, by suddenly darting down on the Pelicans with shrill screams, 

 and striking at them with their talons. I saw this manoeuvre 

 repeated a number of times by a pair of these Ijirds that nested on 

 the island, and by others that came from the shore. They did not 

 attack outgoing birds, but invariably waited for the incoming ones, 

 and as soon as these were over land, so that the contents of the 

 pouches would not fall in the water, they pounced on them, and kept

The Fish Hawk is generally distriljuted throughout Ontario, 

 breeding by the lakes and rivers in the less thickly settled parts of 

 the country. Along the sea coast it is more abundant, frequently 

 breeding in communities of several hundreds. In such cases the 

 nests are placed indifferently on rocks or trees, and sometimes the 

 eggs have been deposited on the sand. Near these breeding places,
