"However, mastering a Transfiguration spell such as "Avifors" can be both rewarding and useful."
The Standard Book of Spells, Grade 2[src]

The Avifors Spell[4] (Avifors[1]) is a transforming spell that could be used to change the target into a bird,[1] flock of birds[2] or occasionally a flock of bats[3] with a vivid flash of blue light.[2]


"Avifors" can, at times, be a very complicated spell and some beginning Hogwarts students are known to struggle with it. One student nearly failed the class when he proved unable to transform objects into anything more than eggs. His cousin bragged about this.[5]


When used in an offensive manner, a jet of blue light will shoot from the witch or wizard's wand, erupting upon hitting the target and solidifying them into a bird, a flock of birds, or more rarely, a flock of black bats[3]. These bats can be controlled by the caster, although they may also fly away[3].

"Avifors" should not be confused with "Avis", a spell to conjure a flock of birds but does not involve any transformation.[2]

This charm was learned in first year and revised in second year Transfiguration class with Professor Minerva McGonagall, and was included in The Standard Book of Spells, Grade 2 by Miranda Goshawk.[2]
