Just last month the Toledo Zoo was celebrating the birth of a rare kiwi chick, but on Thursday zoo officials announced that she had died suddenly.
A press release on the loss said "a specific cause for the death has not been determined; further tests are pending."
Zoo officials added, "the chick had been strong and healthy until recently, when she started to lose weight; blood work revealed a possible bacterial infection. When initial medical treatment did not improve her condition, the Zooâ??s veterinary staff performed surgery to learn more."
It was shortly after that surgery was complete, that the chick died.
The â??Toledo Zoo staff was devoted to her well-being and provided her with excellent care during her short time here. We hope that the results offer information that will help future kiwi populations,â?? Kathy Brader, coordinator of the international Kiwi Species Survival Plan (SSP), at the Smithsonian National Zoological Park in Washington, DC, said.
Kiwi are nocturnal, flightless birds native to New Zealand and are listed as an endangered species.
An estimated 28 kiwi live in U.S zoos accredited by the Association of Zoos and Aquariums (AZA).
