Initially heard from a distance while sitting near the Przewalski's horse exhibit. Followed calls to find it seated in the tree next to enclosure. Individual flew toward American Trail where it flew from tree to tree calling. Common Raven in enclosure responded. Upon returning to the main walkway, we saw two more soaring near three hawks over the enclosure (could only identify one as a Red-shouldered Hawk). Have video of said hawks/ravens.
