Osprey of its finny prey. Its nest also resembles that of 

 H. albicilla and is usually placed on a tree but sometimes also 

 on a cliff or on the ground. Its eggs are also pure white, 2 in 

 number, and are deposited from December to April according to 

 latitude. They measure about 2'89 by 2'26, but eggs from 

 southern latitudes are smaller than those from the high north.
