Though from a distance they appear as normal birds, closer inspection reveals that the beaks of these birds have long protusions, like backwards and downward-pointing mandibles. When a gyrcrow opens its beak fully, these two protrusions touch, and this creates a bladelike bone down their breasts. Gyrcrows are feared for their diving attacks, which slash their targets with wounds that are difficult to close.
Wild Gyrcrows normally only attack in defense of their nests or territories, although in the purple grasses of the Esting they have been said to swarm, and tear their prey apart faster than any sandstorm.
