ABSTRACT
Vomiting in birds is often a more violent action in which the contents of the stomach/crop are expelled out the mouth. The bird may often appear to flick fluid around the immediate environment, and the head feathers often appear wet or stained with vomitus. Behavioral changes can indicate non-specific signs of disease. With many illnesses, birds become less active or even lethargic. In other cases, for example certain intoxications, they can also become hyperactive instead or act very irritated. In case of sudden obvious changes in behavior, it is therefore advisable to have the bird examined immediately. Excessive blood loss quickly leads to problems with blood pressure, resulting in shock or even death. For a small bird the size of a budgerigar, the loss of more than five drops of blood is already threatening. Death in other birds may indicate a severe infectious disease or exposure to toxin.
