  1. What Else?

    The white-bellied sea eagle looks similar to the osprey (Pandion haliaetus) but the eagle is much bigger and has a wedge shaped rather than fan shaped tail.  It could also be confused with a black shouldered kite (Elanus notatus), but kites are much smaller (36cm) compared to the 76-84cm white-bellied sea eagle and have light coloured eyes 

  1. Did You Know?

    Sea eagles are the second largest bird of prey in Australia, after the wedge-tailed eagle. 

    Sea eagles also eat carrion (dead prey), and can also be found eating road kill. 

    They can be seen harassing smaller birds forcing them to drop their foods they can steal it.

    They pair up for life and are territorial.

    They can also be found in China, India, South-east Asia, Indonesia and New Guinea.
