The first hand-rearing of Mauritian white-eyes Zosterops spp Four common Mauritius Grey White-eyes ( Z. borbonica mauritianus ) chicks were hand-reared to help refine hand-rearing techniques in preparation for hand-rearing chicks of the Critically Endangered Mauritius Olive White-eye ( Z. chloronothos ). The first nest rescues and hand-rearing to fledging of chicks of both species at the Gerald Durrell Wildlife Sanctuary on the island are described. There is a feeding schedule for the chicks and a graph that plots the daily weights of the Olive White-eye chicks. There is also a description of the development of the chicks from day one to day 15.
