The cacomistle, Bassariscus sumichrasti, is a nocturnal, arboreal and omnivorous member of the carnivoran family Procyonidae. Its preferred habitats are wet, tropical, evergreen woodlands and mountain forests, though seasonally it will venture into drier deciduous forests.Nowhere in its range (from southern Mexico to western Panama) is B. sumichrasti common. This is especially true in Costa Rica, where it inhabits only a very small area.
