Sans doute mais à voir dans Wikipedia le nombre d'espèces, à moins d'être spécialiste de la faune de cette contrée...

Merci Pascalou. Mais le moment pour moi est venu de regretter d'avoir passé sa scolarité bien au chaud au fond de la classe à coté du radiateur. Honte à moi je ne lis pas l'anglais
Par contre j'écris bien le petit "nègre".
