The San Diego Zoo says it has hatched a brown kiwi chick for the first time in more than a decade.
Zoo staff intervened when the female chick broke through its shell with its feet instead of its head.
It hatched last month but the chick did not eat for six days and lost a quarter of her body weight.
She began gaining weight last week.
The chick is the 11th kiwi to hatch at the zoo, which reared its first brown kiwi in 1983.
The zoo has four kiwi, all living in off-exhibit areas, and the zoo is one of six in the US working with the species.
