Today the biggest eagle in the world is often claimed to be the Steller\u2019s sea eagle, a fish-eating species from North-East Asia.<\/p>\n

Steller\u2019s sea eagles are one of the rarest raptors in the world.\u00a0Birdlife International\u00a0estimate there’s 3600-4670 mature individuals in the wild and say”it is suspected that it will decline at a rate of 20-30% over three generations.”<\/p>\n

However there are other contenders for biggest eagle title. The\u00a0white-tailed eagle\u00a0of Eurasia might just match Steller\u2019s sea eagle in terms of wingspan (both can reach about 2.5m), and the Philippine eagle and\u00a0harpy eagle\u00a0of tropical America might be just as heavy (up to about 10kg).<\/p>\n

For an undisputed winner of all time, you have to go back 600 years. Weighing 15kg and with a 3m wingspan, the Haast\u2019s eagle is thought to be the biggest eagle that ever lived. It specialised in hunting New Zealand\u2019s giant, flightless moas and disappeared in the 15th century after the M\u0101ori hunted the moas to extinction.<\/p>\n
