This paper describes a case of an adult female mallard duck (Anas platyrhynchos) with a traumatic crop injury and the surgical repair of this injury. A brief review of crop anatomy and function is provided, informing how the crop, a diverticulum of the esophagus that is used primarily for food storage, can serve other, more complex functions. Additionally, a brief review of various suture patterns used in gastrointestinal surgery is provided, showing that while many techniques are possible, including one- and two-layer closure using appositional or inverting sutures, all have a good rate of successful closure and can well withstand bursting tension.
