Auspices
The word "inauguration" is derived from the Latin noun inauguratio derived from the verb inaugurare which was to "take omens from birds in flight." Since Roman augurs predominantly looked at birds for omens, they were also called auspex ("bird watcher", plural auspices), however they also interpreted thunder, lightning, the behavior of certain animals, and strange events. The phrase "under the auspices" is derived from this need for a favourable reading of the omens by the augurs.
