Lincoln Park Zoo in Chicago welcomed a baby eastern black rhinoceros in March! This is especially happy news because eastern black rhinos are critically endangered, and every birth helps bolster their population.

The female calf weighed around 27 kg (60 lb.) at birth and took her first steps just an hour and a half after being born! She and her mother, Kapuki, are being monitored by zoo staff.

According to Curator Cassy Kutilek, “Mom and calf are doing well and continue to hit their postpartum milestones, and we’re excited for when we’ll start seeing glimmers of the newborn’s personality.”

In the wild, the eastern black rhino population dropped 98% between 1960-1995 due to poaching. Due to conservation efforts, there are now around 1,000 mature individuals in the wild.

One Month Update

Nonami has also successfully given birth at her previous zoo to two females who now live at Oakland Zoo: Ikea and Skittles.

Nonami and her new baby have joined the rest of the troop in their habitat, and the baby’s sister, Ikea, has shown strong interest in her brother and wants to help Mom with grooming while Nonami supervises.

Rattlesnake babies are shaking things up at Lincoln Park Zoo in Chicago! Nine eastern massasauga rattlesnakes hatched at the zoo in February. Their birth marks a huge milestone in massasauga rattlesnake conservation: the first birth of their kind at the zoo in nearly a decade.

These baby rattlesnakes are the great grandkids of the last few remaining eastern massasauga rattlesnakes in Cook County, Illinois.

Their population has faced critical threats due to persecution and habitat loss. The zoo, along with state and federal authorities, have been working together for years to conserve this often-misunderstood snake species.

“People tend to fear eastern massasauga rattlesnakes because they’re venomous, but they’re actually a rather shy species and an important part of the Great Lakes region’s ecosystem,” said Curator Dan Boehm.

“It’s always exciting to welcome new offspring of a threatened species, and the fact that this is a local animal we’re actively working to conserve out in the field makes it even more special.”

Eastern massasauga rattlesnakes can be found in wetland habitats around the Great Lakes in the United States and Canada. Measuring at about two feet long on average, this species is on the smaller side for rattlesnakes.

Oakland Zoo Rescues Female Mountain Lion Cub

Earlier this month, Oakland Zoo in California helped rescue a female mountain lion (or cougar) cub. She was found emaciated and wandering near a road. She is about three months old, based on her coloration and tooth development.

California Department of Fish and Wildlife (CDFW) performed initial veterinary exams on the cub and found her to be severely underweight, weighing less than half her ideal weight, and covered in ticks. They treated her for dehydration and tick infestation.

Clover received around-the-clock care at Oakland Zoo Veterinary Hospital.

The cub, now named Clover, was then transferred to Oakland Zoo Veterinary Hospital. After further evaluation, zoo vets determined that Clover was in critical condition.

She received around-the-clock intensive care in the hospital’s ICU, including a blood transfusion using blood donated from a resident cougar at the zoo named Briar.

The Lincoln Park Zoo in Chicago announced the arrival of a new African penguin chick! After a 40-day incubation period, the baby penguin hatched on October 1.

The chick was born to parents Rosie and Cecil. However, Rosie and Cecil have not been successful in raising chicks in the past, so the Animal Care team has decided this chick will be raised by penguin pair Liam and Maria, who have strong parenting instincts.

“As a critically endangered species, each new African penguin chick represents an immense amount of hope for the species’ future,” said Hope B. McCormick Curator of Birds Nicole Finch-Mason.

At this point, the chick remains behind-the-scenes. Soon it will begin exploring outside its nest box. It currently weighs 1.9 kg (4.2 lb.) and has downy feathers.

Once it grows its juvenile waterproof feathers in a few weeks, it will join the other African penguins in the zoo’s colony on exhibit. After 1-2 years, the chick will molt into its adult black and white plumage.

The Taronga Wildlife Hospital in Dubbo, Australia provided life-saving care to a sick koala joey, named Hank.

When Hank arrived at the hospital in January, he was dehydrated and lethargic. Veterinary staff provided 24-hour intensive care for weeks, giving him IV fluids, medication and a special milk diet. Now Hank is thriving.

“After being in round-the-clock care the past few months, coming home with me at night and being at the Wildlife Hospital during the day, Hank has now been weaned and is adjusting to his leaf only diet,” said Taronga Western Plains Zoo’s Senior Veterinary Nurse, Jodie Lardner-Smith.

Hank is currently living at the wildlife hospital. But he will be introduced to other koalas in a rehabilitation enclosure so he can learn necessary koala life skills. This will prepare him for his eventual return to the wild.

Hank is one of the 700 sick, injured or orphaned native animals cared for by the Taronga Wildlife Hospital Dubbo every year. To help even more animals, Taronga is building another wildlife hospital in Sydney. Visit the Taronga website for more information.

Humboldt penguins are native to the western coastline of South America near Peru and Chile. They are considered vulnerable of extinction by the IUCN Red List.

Researchers estimate the wild population to be under 24,000. Brookfield Zoo Chicago has led a conservation program at Punta San Juan for nearly 20 years to help bolster the population.
