Laysan Duck
Anas laysanensis
Body length, 38 - 43 cm; wing length, 19.2 - 20.4 cm
348 - 548 g
Estimated at 500 - 680 matured individuals
Dense forest during the day; hypersaline lake at night
Squeezed. The laysan duck has the most limited range of any duck species in the world- just 11.2 square kilometers- making it especially vulnurable to calamities like disease, competition from introduced animals and extreme weather. Pairs form long-term bonds that can last nearly their entire lives. They spend most of their daylight hours under dense forest cover; at night, they emerge to make meals of brine flies, brine shrimp, moth and beetles. but with little room to roam, danger is never far away.
