The swift parrot of southeastern Australia is critically endangered with fewer than 300 individuals remaining, facing habitat destruction and introduced predators that threaten both its survival and individual welfare.
Individual swift parrots face sugar glider predation at nest holes in brutal attacks. Habitat loss forces birds to travel greater distances for food, increasing energy expenditure and stress. Females are disproportionately lost to predation, skewing the sex ratio and reducing breeding success. This species faces extinction within years without intervention.
