What material is often used to prevent bleeding in avian patients?

Corn starch is often used to prevent bleeding in avian patients due to its absorbent properties. When applied to a bleeding area, corn starch can help to form a paste that aids in clotting by absorbing moisture, which promotes the formation of a scab. This is especially important in birds, as they can lose blood rapidly due to their small size and high metabolism.

In contrast, tissue glue is commonly used to close wounds but does not specifically address bleeding control. Plaster is not suitable for wound management in avian patients and does not provide any hemostatic properties. Wood glue is a non-medical adhesive that is not safe for use in animals, as it may contain toxic compounds or cause irritation. Thus, corn starch remains the preferred choice for promoting clotting and managing minor bleeding in birds.
