What Is the Largest Bird of Prey?

The largest active-hunting bird of prey is the Martial eagle with a wingspan of 2.6 meters. Among condors, which are also considered birds of prey though they are primarily scavengers, the record belongs to the Andean condor, which has a wingspan of 3 meters and weighs up to 15 kg.

The Martial eagle lives in Africa, and is known to be an aggressive hunter, feeding on prey as large as baboons, lion cubs and antelopes. Nearly as large as the Martial eagle is Stellar's sea eagle with a wingspan of 2.5 meters. It is the world's heaviest eagle, weighing up to 9 kg. It feeds primarily on fish but has been known to hunt cranes, swans and even juvenile seals.
