>>40123403Who said Nazguls have dense bones? They can be modeled after pterodactyls which are large, have even more hollow bones than the birds & can fly thanks to the more efficient webbed wings. The benefits of webbed wings far outclassed their weight.
Meanwhile, the biggest flying bird, have bigger wingspans than those eagles. So the eagles need to flap their wings much faster to fly which gives them faster dive speed but way slower climb speed & the Nazguls can eat them during the climb. Large birds also have proportionally larger legs that weighed them down since they need them to take off.
