Andean Condors Andean condors face a shrinking habitat and, therefore, a decreasing prey population. As a perceived threat to livestock and other domesticated animals, they also face persecution from humans. These great birds provide a necessary service as recyclers and scavengers. Eating carrion, Andean condors help prevent the spread of disease and toxins; they are nature’s clean-up crew. Conservation efforts are necessary to bolster populations and previous reintroductions into the wild have been promising.
