In this pilot study, the group is using specialized fixed-wing drones to survey vast stretches of the Mojave Desert for signs of ravens. Ravens are a subsidized predator of tortoises in the Mojave. This means that their population is much larger today due to water and food they are able to get from human presence. Not only that, the addition of trees and power poles give the birds unprecedented perching, nesting and shade. This allows them to penetrate deeper into tortoise habitat where they prey upon young tortoises. A single nest can consume over 100 young tortoises in a single spring.
