Fischer's lovebird is a very active and small parrot that is mostly green in body color and has pink abdomen. One of the main symptoms of a bird being ill is that it will stop eating and drinking. If your bird stops eating, the first thing you should do is examine its droppings to see what the consistency is like. If the droppings are soft, slimy and contain a lot of liquid, or if the droppings are tiny and hard, like little pebbles, then your bird is most likely suffering from dehydration. If your bird's droppings do not return to normal after a day or two, then this is most likely due to a secondary infection like bacteria, virus or parasites. That is why you should bring your lovebird to a vet as soon as possible. The vet can then give your bird an antibiotic and/or anti parasitic to get rid of the secondary infection.
