In 1997, Phillipe de Vosjoli and Frank Fast explored the tiny island of Nuu Ami.. This island was infested with rats and they encountered them commonly in tree hollows where they would have expected leachianus. Rats commonly roamed the edges of the shore at night. They did find a few leachianus, primarily in trees during the day. One specimen was on the ground in a hollow at the base of a tree. Ants were also abundant here. This unique population of leachianus is on the verge of extinction. Like Nuu Anas, they are an ecotype 3 variant, and primarily frugivorous.
