Andean condors are listed as endangered in Colombia, Venezuela, and Ecuador and vulnerable across many other countries in South America. This species is persecuted by livestock farmers who worry about their lambs and calves and by seabird guano workers attempting to keep condors from scavenging on chicks. They are captured for traditional rituals, collide with power lines, and are losing food sources to habitat loss and competition with feral dogs. The persecution of mountain lions and foxes through the illegal poisoning of carcasses also results in secondary poisoning of condors and other vultures throughout their range. Increased tourism in parts of Chile and Argentina may have led to a reduction in persecution by demonstrating the ecotourism value of the species (S. Imberti in litt. 2003).
