Infected birds pass bacteria in their fecal droppings. Other birds then become ill when they eat food contaminated by the droppings. Bird extinction Out of the approximately 10,400 known bird species, about 1,300 (13%) are classified as threatened with extinction, 9% as near threatened and of the remaining 78% many populations are declining. There is a general consensus among scientists who study these trends that if human impact on the environment continues as it has one-third of
