In avian species, the [[Lips - Anatomy & Physiology|lips]] and [[Cheeks - Anatomy & Physiology|cheeks]] are replaced by the [[Skin - Anatomy & Physiology#Cutaneous Appendages|beak]].

The [[Skin - Anatomy & Physiology#Cutaneous Appendages|beak]] is an area of dense, horny skin overlying the [[Skull and Facial Muscles - Anatomy & Physiology#Incisive Bone (os ncisivium)|incisive bones of the [[Skull and Facial Muscles - Anatomy & Physiology#Mandible (mandibula)|mandible]].

No modern birds possess [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology|teeth]], however rudimentary [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology#Anatomy of the Enamel Organ|enamel organs]] have been discovered in the embryos of some birds.
