作为岛上天空的霸主，阿根廷巨鹰几乎没有任何对手。但值得岛上其他鸟类生物庆幸的是，阿根廷巨鹰对活着的生物不太感兴趣。 与我猜测的相去甚远，阿根廷巨鹰并没有进化出像现代秃鹰一样弯曲的脖子。 我不知道它是否是为了对付岛上的捕食者才进化出了强壮的脖子，又或者是因为它的家族诞生于弯曲的脖子在食腐鸟类间流行之前。无论如何，它让阿根廷巨鹰可以用喙叼起小型生物。
Common name: Argentavis
Species: Argentavis atrocollum
Time: Late Miocene
Diet: Carrion Feeder
Lording over the skies across the Island, Argentavis atrocollum has few aerial rivals. It is a small consolation for the Island's other avian creatures, then, that Argentavis seems to have little interest in anything alive. Quite apart from what I would have guessed, Argentavis does not have the stooped neck typical of modern buzzards and vultures. I don't know if it adapted this stronger neck to deal with the predators on the Island, or if its lineage derives from before the stooped neck became common in carrion-eating birds. Whichever it might be, it has enabled Argentavis to carry smaller creatures with its beak.
Argentavis is actually slower than the Island's far more common Pteranodon, but it possesses significantly more stamina and can sustain flight for approximately three times as long. Its weighty stature, in comparison to the Pteranodon, allows it to utilize its talons to support the weight of an additional passenger. Considering its saddle doubles as a mobile crafting station, it makes Argentavis an excellent creature for traveling and hauling cargo over long distances.
