It is well known that the introduction of alien species by humans has been responsible for a long list of extinctions on islands. Enhancing methods of pooling information on effectively reducing these human-caused threats to island populations can’t come soon enough. Both species represented in this painting are at risk. The Espanola Mockingbird (Mimus macdonaldi) is classified as Vulnerable. The egg represents a Green Turtle (Chelonia mydas), which is Endangered. The nests of both the bird and the turtle are vulnerable to the same terrestrial threats--nest predation from introduced feral cats and rats. The nest that sheltered this turtle egg was probably exposed by one of their brethren.
