Walnut, a white-naped crane and internet celebrity, has passed away at age 42. That preference continued when she came to the institute; she showed no interest in breeding and even attacked male crane suitors. Photos You Should See View All 45 ImagesBut white-naped cranes are considered vulnerable by the International Union for Conservation of Nature. And as the offspring of two wild-caught cranes, Walnut’s genes were not represented in U.S. zoos. Once Crowe had gained her trust, he was able to artificially inseminate her using sperm from a male crane.

CNN —The mountain chicken frog was once so abundant in Dominica, with thousands found across the island, that it became a national delicacy, supposedly tasting of chicken. Chytridiomycosis is a fungal infectious disease that affects more than 500 frog species across the world. A research team spent 26 days searching for the mountain chicken frog in Dominica. The research team spent hundreds of hours searching for the chicken frog during the months of July and August. “There are many things that people can do to prevent the spread of chytrid and help protect frogs,” Kaganer said in an email.

David Willard has been checking the grounds of Chicago's lakefront exhibition center for dead birds for 40 years. Researchers estimate hundreds of millions of birds die in window strikes in the United States each year. When they see plants or bushes through windows or reflected in them, they head for them, killing themselves in the process. Pre-dawn rain forced the birds to drop to lower altitudes, where they found the McCormick Center’s lights on, Willard said. The first buildings at McCormick Center were constructed in 1959.

The 26-year-old bear, Tian Tian, along with two other pandas in the zoo, are slated to leave by December 7. On Sunday, Tian Tian received a special “fruitsicle” cake made with fruits and vegetables with a “frosting” of sweet potatoes, mashed carrots and honey for his birthday, the museum said. The National Zoo’s Giant Panda Program celebrated its 50th anniversary in 2022. Mei Xiang and Tian Tian first arrived at the zoo in the early 2000s and were originally supposed to stay for 10 years. According to the National Zoo, giant pandas have an estimated lifespan of about 15-20 years in the wild and about 30 years in human care.

Now, scientists have announced a potential new method of feline contraception that’s shown early promise: long-lasting contraceptive injections that prevent ovulation. “That’s what led us to start collaborating with Bill (Swanson).”The Cincinnati Zoo, Swanson says, is home to the widest array of wild cats in North America, including lions, tigers and tiny sand cats. Three cats were a control group, while six received injections of the gene of the hormone in question, hitched to a mild virus. The three control-group cats all became pregnant, but none of the six cats in the experimental group did. “We’re really focused on adopting these cats out,” said Swanson, who’s adopted three cats from earlier studies.

☆ Moving species emerges as last resort as climate warms

Moving species to save them — once considered taboo — is quickly gaining traction as climate change upends habitats. Concerns persist that the novel practice could cause unintended harm the same way invasive plants and animals have wreaked havoc on native species. “Climate change is causing a greater need for this — for taking a species outside its known historical range.”A pending change to the U.S. “In the future, some species’ ranges may shift due to climate change, or their current habitats might become unsuitable due to invasive species encroachment,” Armstrong said in an email. Humanity has been moving species around for centuries, often inadvertently and sometimes causing great harm.
