The Seychelles are so small and so isolated that few mammals reached the islands before human beings. The Seychelles magpie robin got its name because European visitors thought it behaved like a European robin, even though it looked like a magpie. There was once a large population of giant tortoises across the Seychelles. Because of their weight, their legs dig into the ground as they walk, disturbing the soil. Even though the robins are now even rarer than the tortoises, they are still seen together. The robins eat the insects revealed as the tortoises move around.
