Once you learn the signs of early illness, needed treatments can be performed by your avian veterinarian. Some of the best indicators of health is the bird's droppings. The droppings are made up of feces, normally black or dark green. With this will be urine, which is clear, and urates, a creamy white waste material. Droppings with a mustard yellow liquid portion is not normal, nor is blood or rusty brown color in feces.
Healthy birds eat often and make lots of droppings.
A sick bird may have fewer droppings, or no fecal portion in them, just white and liquid. Another indicator of illness is change in eating and drinking habits, for example, excessive water consumption. A bird who isn't interested in food indefinitely is ill. A change in attitude or behavior can signal illness. Any of these symptoms indicates potentially serious problems.
