Avis is a spell that conjures a flock of birds.
This spell was used by Ollivander when testing the four Triwizard Tournament Champions' wands before their First Task. This is also possibly the spell that the sixth-year Charms students were learning to perform nonverbally in 1996; that same year, Hermione Granger used it to conjure a flock of canaries and made them attack Ron Weasley.
