|Previously published Red List assessments:|
|Range Description:||Zapornia sandwichensis occurred on the east side of Hawai'i, USA, and may also have occurred on Molokai (Pratt et al. 1987). It is known from bones and a number of specimens (Olson and James 1991), and was illustrated by Ellis on Cook's third voyage (Stresemann 1950). The last specimen was collected in 1864 and the last report was in 1884, or possibly 1893 (Taylor 1998).|

|Population:||See Geographic Range text.|
|Habitat and Ecology:||It inhabited clearings in upland forest.|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||2.7|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||The timing of its extinction indicates that it was perhaps not caused by mongooses, as they were not introduced until 1883. More probably, it was due to a long process of predation by rats, cats, dogs and people (Taylor 1998).|
