Kiwis are the national symbol of New Zealand, but this soon may be a statement of the past, according to Scientist Dr. Tom Jensen of the Beckman Center for Conservation and Research for Endangered Species. Despite his Danish roots, Dr. Jensen has a passion for saving this endangered bird.

These days, kiwis in the wild are declining at dramatic rates. Currently, only about five percent of all conceived chicks survive to adulthood. Since kiwis are native only to the islands of New Zealand, you may be wondering, “What can outsiders do to help”? Dr. Jensen and his expert team have honed in on several key areas in hopes of enhancing kiwi conservation efforts. Handling the birds as little as possible is crucial, so instead of drawing blood, fecal steroids are analyzed to assess reproductive status. Dr. Jensen monitors captive females at the San Diego Zoo on a routine basis using a portable ultrasound device. Repeated measurements not only track ovarian follicle growth but also help to monitor ovulation cycles. If researchers can collect sperm from male kiwis, then this valuable ultrasound data will help determine the best time to inseminate females.

Part of the kiwi project includes collecting fecal samples. DNA can be extracted from these samples, lending support to Dr. Jensen’s proud assertion that “Poop is good!” DNA from fecal samples can also be used to identify individuals within a population, genetic diversity, and even kiwi paternity! Surprisingly, DNA studies have shown that kiwis are not always monogamous breeders.

Whether you’re Danish or a New Zealander, kiwi survival is a serious matter. Efforts to save this unique species will only be successful when chick survival rates increase to 20 percent or more. As Dr. Jensen’s efforts have demonstrated, conservation is a universal necessity that needs global cooperation.
