I get articles from all over the U.S. I also order books also.I can share information about every fossil bird if anyone is interested. I think information from the "Proceedings of the Bioloogical Society of Washington" is most sorely missed. For example, for this very bird here. |

How can order articles from the Proceedings of the Biological Society of Washington? I see that it is not possible online.There are many articles I'd like to get my hands on.

The Malagasy Crowned Eagle (Stephanoaetus mahery),[1] also known as the Madagascar Crowned Hawk-eagle, was a gigantic bird of prey that inhabited Madagascar until 1500 AD. Many Scientists have pointed out that the bird shows many similarities with Haast's Eagle (Harpagornis moorei) and it is likely that it had a similar diet, feeding on the giant Elephant birds of the time. It is also likely that Giant lemurs were part of its diet. It was perhaps an Apex predator of the Malagasy forests along with the Giant Fossa and the two species of crocodile. It likely became extinct due to human overhunting of its prey and possibly was hunted as well.[2] [edit] References 1. ^ Stephanoaetus mahery (No common name) 2. ^ Human Settlers Invade Paradise Endangered Species Handbook en.wikipedia.org/wiki/Malagasy_Crowned_Eagle |

I would really like to know how big this bird actually was. In any way, I can hardly imagine that it really preyed on adult elephant birds.

Me too. Commonly you can say it was smaller than the Haast's Eagle. I would really like to know how big this bird actually was. In any way, I can hardly imagine that it really preyed on adult elephant birds. |

Recently a subfossil eagle, Stephanoaetus mahery Goodman, 1994, has been described from the Quaternary of Madagascar that may have been able to feed on lemurs of considerable size (Goodman 1994). However, this raptor would not have been able to predate on the adults of the larger extinct lemur species, several of which weighed more than 30 kg. www.mnhn.fr/museum/front/medias/publication/1334_z04n1a9.pdfI think this shows very good that Stephanoaetus mahery was not able to fed on Elephant birds. |

I would not completely rule out that it even killed the largest lemurs (except Archaeoindris) at least on occasion. Golden eagles were for several times recorded to kill ungulates up to a weight of 100kg, like deers, rendeers, wild goats, antelopes and in one case even several calves. The african crowned eagle is also know to attack often prey which is much larger than itself, indlcuding big mandrills and medium-sized gazelles. The talons of such big and strong raptors are really lethal weapons, and they have the potential to kill even very large animals if they attack their backs, heads or necks. And there was nearly no competition on a carcass at Madagascar not very unsimilar to New Zealand.
So perhaps the malagasy crowned eagle killed really sometimesthe big Megaladapis and Palaeopropithecus species as well as young specimens of Hippopotamus madagascariensis. But adult elephant birds are highly inlikely.
