feathers
Clinical description:
Birds have several types of feathers distributed across various regions of their body including down, body feathers, and flight feathers. Look for abnormalities in feather conformation such as warping or malformed barbs and barbules. Make note of any body regions that are missing feathers. Feathers are normally distributed along tracks on the body, called pterylae. These tracks are interspersed with featherless tracts called apteria. Keep in mind, that not all feather loss is abnormal. Seasonal feather molting is a normal physiologic process. Additionally, females who are incubating eggs may have an area on their abdomen lacking feathers, called the brood patch. In non-pathologic feather loss, the skin will appear healthy. In cases of pathologic feather loss, such as excessive feather picking by the bird, or its cage mates, the skin will be traumatized.
