For the First Time Ever, a Mammal Has Been Declared Extinct Due to Climate Change

An Australian rat-like rodent called the Bramble Cay melomys is the first known mammal wiped out by manmade climate change, The Hill reports. The now-extinct animal (Melomys rubicola) lived on the tiny, uninhabited island of Bramble Cay in the Great Barrier Reef. Despite exhaustive efforts to track down the melomys over seven years, no signs of the rodent could be found, and in 2016, Queensland’s state government declared the animal extinct.

These fears were confirmed when news broke this week that the national government had quietly changed the rodent’s classification from endangered to extinct. Meanwhile, the status of a fruit bat called the spectacled flying-fox was changed from vulnerable to endangered after a recent heatwave in north Queensland, which dealt another blow to a population that had already been cut in half over the last decade.

As for the Bramble Cay melomys, its demise can be attributed to rising sea levels, storm surges, and other weather events that have worsened due to climate change. According to The Revelator, the tides destroyed about 97 percent of the island’s vegetation, which was the rodent’s only food source.

Leeanne Enoch, Queensland's Minister for Environment and the Great Barrier Reef, told The Sydney Morning Herald that the latest animal extinction is evidence “we are living the real effects of climate change right now.”

In a 2018 study commissioned by the World Wildlife Fund, researchers found that up to half of the 80,000 plant and animal species that reside in 35 of the world’s most diverse areas could become extinct by the turn of the century because of climate change.

For some species, it’s already too late. A Hawaiian bird called the poo-uli (or black-faced honeycreeper) was declared extinct last year, largely due to diseases carried by mosquitoes, which thrive in warmer climates. For other endangered species in the U.S.—like the black-footed ferret, red wolf, and rusty patched bumble bee—there might still be time to step in and protect them.

The Tower of London Welcomes New Baby Ravens for the First Time in 30 Years

There are some new residents at the Tower of London. They're only about 11 inches tall, are very noisy, and eat rats for breakfast, lunch, and dinner. Fortunately, they're also adorable—not to mention protected by legend.

On May 17, the Tower of London announced that their breeding pair of ravens, Huginn and Muninn, had welcomed four healthy chicks, the first born at the Tower since 1989. The ravens are part of an unkindness that's been located at the Tower for centuries as a sort of protective asset. According to legend, the Tower must always have ravens, or both the Tower and the kingdom will fall. It's not exactly clear when the legend began, but according to the Tower, Charles II decreed there must always be six ravens present.

Huginn and Muninn are newer additions, having arrived at the Tower in late 2018, and they weren't expected to breed this spring. So it was a surprise in mid-April when the devoted Tower Ravenmaster, Yeoman Warder Chris Skaife, noticed something exciting going on. "My suspicions were first piqued that we might have a chance of baby chicks when the parents built a huge nest suddenly overnight and then almost immediately the female bird started to sit on it," Skaife said in a Tower press release. On April 23, Skaife noticed the birds flying to the nest with food, but it was only this week he was able to get close enough to see the four healthy chicks. The sight delighted him: "Having worked with the ravens here at the Tower for the last 13 years and getting to know each of them, I feel like a proud father!"

The chicks have grown quickly, already quadrupling in size since they were born, and eat a diet of quail, rats, and mice the Ravenmaster provides. The raven parents have an egalitarian feeding arrangement: Huginn, the male, preps the food and passes it to Muninn, the female, who feeds it to her tiny chicks.

The plan is for one of the chicks to stay at the Tower and join the rest of the ravens there. "As the ravens started to hatch on the 23 April, St. George’s Day, the raven that will be staying at the Tower will be called George or Georgina in honor of the occasion," the Tower explained in a press release. According to The Telegraph, the breeding program at the Tower kicked off in response to a decline in the number of legal raven breeders in the UK.

The last raven chick born at the Tower was Ronald Raven, born May 1, 1989. In his 2018 book, The Ravenmaster: My Life with the Ravens at the Tower of London, Skaife wrote that "a baby raven looks a bit like a grotesque miniature gargoyle, but then you see them grow and develop ... It really is wonderful."

Dozens of Donkeys, Mini-Donkeys, and Baby Donkeys Are Looking for New Homes

Cats and dogs aren't the only rescue animals that need permanent homes. At the Humane Society of North Texas (HSNT), there are over 60 donkeys, miniature donkeys, baby donkeys, and Thoroughbred horses up for adoption, the Cleburne Times-Review reports.

Many of the equines at HSNT's ranch in Joshua, Texas came from owners who had to give them up, and others were transferred from different animal rescue groups. As part of the ASPCA’s Help A Horse Home Challenge, HSNT is hosting events to help find new homes for its horses and donkeys.

Between April 26 and June 30 this year, the ASPCA is challenging equine organizations to adopt out as many animals as they can. The groups that see the biggest increases in adoptions between this year and last year's Help A Horse Home Challenge will share $150,000 in grant funding. On May 18 and June 8, HSNT is holding open houses at its ranch for anyone interested in adopting an animal. The events will also be used as opportunities to educate the public about the demands of equine ownership.

If you're not free to swing by one of HSNT's open houses, you can still apply to adopt a horse or donkey. Interested owners can fill out and submit this form [PDF] to equine@hsnt.org. And if you'd like to spend time with baby and mini-donkeys without taking one home, HSNT is also looking for volunteers.
