A baby western lowland gorilla was born on May 27 at the Smithsonian National Zoo and Conservation Biology Institute in Washington, D.C., leaving zoo personnel "overjoyed," a press release announced.

The gorilla was born sometime between midnight and 6:15 a.m., said the zoo. 

The animal's parents are 20-year-old Calaya and 31-year-old Baraka. 

The baby gorilla is the first gorilla in five years to be born at the zoo. The last western lowland gorilla to be born at the zoo was a male named Moke.

Moke is also the offspring of Calaya and Baraka, said the zoo in its release.

The newborn's sex and other characteristics are yet to be determined, said the release. Zookeepers are letting mama gorilla Calaya bond and care for her child without human interference, and are "cautiously optimistic" that the newborn gorilla will thrive.

"We are overjoyed to welcome a new infant to our western lowland gorilla troop," Becky Malinsky, curator of primates at the National Zoo, said in a press release (groups of gorillas are called "troops"). 

"Calaya is an experienced mother, and I have every confidence she will take excellent care of this baby, as she did with her first offspring, Moke," Malinsky went on. "Since his birth in 2018, it’s been wonderful seeing her nurturing and playful side come out."

"I encourage people to visit our gorilla family and be inspired to help save this critically endangered species in the wild," said Malinsky. 

The National Zoo's Great Ape House was closed until May 30 to give mother and child additional privacy, said the zoo. 

The zoo is interested in seeing how parents Calaya and Baraka, along with their first offspring, adapt to their new addition, they noted.

"Baraka has a relaxed and playful personality; over the last few years, he has been very tolerant of his 5-year-old son's antics," said the National Zoo.

"Keepers are most excited to see how Moke will react to and interact with his new sibling — especially once the baby becomes active and independent." 

The National Zoo announced Calaya's pregnancy in a March 23, 2023, press release. 

The zoo explained that she bred with Baraka in September 2022, and that "a common human pregnancy test" was used to determine she was pregnant. 

"As we prepare to welcome a new western lowland gorilla to our troop, we hope this baby’s impending arrival inspires the public to care about these charismatic, intelligent and fascinating animals," Malinsky said at the time.

"Every new birth contributes to the conservation of this species, as they are critically endangered in the wild."

The World Wildlife Fund estimates that the number of wild western lowland gorillas has decreased by 60% over the last two decades due to poaching and disease. 

The big cheese of extreme U.K. sports events is back.

Hundreds of spectators gathered Monday to watch dozens of reckless racers chase a 7-pound wheel of Double Gloucester cheese down the near-vertical Cooper’s Hill, near Gloucester in southwest England.

The first racer to finish behind the fast-rolling cheese gets to keep it.

The cheese-rolling race has been held at Cooper’s Hill, about 100 miles west of London, since at least 1826, and the sport of cheese-rolling is believed to be much older.

The rough-and-tumble event often comes with safety concerns. Few competitors manage to stay on their feet all the way down the 200-yard hill, and this year several had to be helped, limping, from the course.

Canadian contestant Delaney Irving, 19, won the women’s race despite being briefly knocked unconscious.

"I just remember hitting my head, and now I have the cheese," said Irving, who comes from Nanaimo, British Columbia.

Matt Crolla, 28, from Manchester in northwestern England, won the first of several men’s races. Asked how he had prepared, he told reporters: "I don’t think you can train for it, can you? It’s just being an idiot."
