Most parrots weigh between 50g and 1.5 kg. Of course they should loose as little blood as possible, if a surgery should ever be necessary.
Laser endoscopy and laser surgery bring a major advantage in birds: The laser beam heat-seals the vessels while cutting and minimizes bleeding. The wound healing is rather fast and, by using laser beam, bacteria and viruses as well as fungus are inactivated.
Laser endoscopy: in use in the abdominal cavity, in the crop, in the cloaca, in the ventriculus or in the trachea
Laser surgery: in use from the outside for example when we are dealing with tumours, feather cysts or just for wound treatment
