The Esophagus
The esophagus conducts food from the mouth to the stomach in all animals. In this case with birds it goes to the gizzard first before the proventriculus (a birds stomach). The gizzard acts as "teeth" for a bird- breaking food into smaller particles to give a larger surface area to food consumed which improves digestion.
The peristaltic movements are muscle contractions and its function on the esophagus is to push food down into the stomach and prevent it from going back into the esophagus.
