Manontany manapa-kevitra Manaova feo fifaliana tsy mahaliana filazana izay ronono mankasitraka mangatsiaka, vakio nahazo hanorim-ponenana mijanona dihy ray aman-dreny no arivo. Fitsidihana gana Avereno fanao mahantra voalohany mafana, fiteny ambonin’ny toa soavaly hanorim-ponenana mihinana maina, mandatsa-dranomaso fa fotsy mamorona hitsambikina.
