The mountain chicken Frog (Leptodactylus fallax) is native and listed on the iUcn Red List as "critically endangered" due mainly to overhunting, habitat loss, and the effects of chytridiomycosis. Eleutherodactylus amplinympha and E. martinicensis are native, and the former is an island endemic. Eleutherodactylus johnstonei is invasive and thought to have arrived on the island in the aftermath of Hurricane David in 1979. However, it has not been found during recent surveys. Using timed 50-and 100-m transects, we surveyed five sites at different elevations and subjected to varying levels of human and natural disturbances to assess frog numbers, microhabitat associations, and perch heights. Both E. amplinympha and E. martinicensis used available habitat, demonstrating no apparent bias for particular perches or microhabitats. Both species are polymorphic, but no variation in colour or pattern appears to be specific to either species. Herpetological Bulletin [2009] -number 108 15
