Herlit

"The Gorean eagle; an adult herlit is generally four feet (4') in height with a wingspan of seven to eight feet (7'-8'). The herlit is carnivorous. A valuable bird amongst the tribes of the Barrens, especially for its tail feathers, which are some fourteen to fifteen inches (14"-15") in height and are yellow in color with black tips. The herlit is also called "Sun-Striker" or "out-of-the-sun-it-strikes," from its habit of striking with the sun above and behind it; inhabits the Barrens."

Quite a clever idea for a AV, still waiting to hear back from the owner of IOW as to whether she could build me a tarn adapted from the Gryphon....

maybe I should check out Grendels again, see if they have anything...
