Why is the Laysan Duck endangered?

They were threatened when mankind first colonized their lush islands. Humans brought rats, pigs and other non-native species of invasive ground predators. They are more likely to sit stock still when startled, making them easy prey for those ground-based predators. Ravenous rabbits nearly brought them to extinction in 1912. The IUCN currently has them Red Listed as 'Critically Endangered'.
