Ostrich

This actor is part of the African Animals series, created by Tamás Zsolt Nagy.

Ostrich is a vector based animal character with Spring Bones and 360 Head capability. 
Although it's a bird, it is based on quadruped bone structure. When you apply animal motions, you can use either horse or dog types. Obviously, not all of the quadruped motions will be compatible, but walkings and runnings typically work fine.
FREE TRIAL is available, so you can download and test it before you would purchase it.
