The title of largest owl in the world belongs to the Blakiston fish owl.
Fully grown males weigh about 3.5kg, while the slightly bigger females can reach 4.6kg. More impressive, however, are the Blakistons’ wingspans, which can be up to 200cm.
Blakiston fish owl is found in China, Japan and north-eastern Asia, and to cope with the cold its feet are fully feathered.
As its name suggests, the Blakiston fish owl preys on river-dwelling fish such as pike, catfish, trout and salmon, however if it is hungry amphibians and even small mammals are also on its menu.
They are also one of a number of species that mate for life
