Mantises Regularly Catch and Feast On Birds, NBD

The next time you feel like you’re too small to make a difference, think of the mantis. Scientists have discovered that many species of these badass little bugs habitually hunt, kill, and devour entire birds. A report on the mantises’ impressive skills was published in The Wilson Journal of Ornithology.

It’s not like we thought mantises were vegetarians. Their taste for flesh, including each other's, is common knowledge. But so was their basic diet, which consists of bugs and spiders. Once in a blue moon, someone might spot a mantis eating a tiny lizard or a small snake—you know, animals that live on the ground. But birds? Like, the kind with wings? No. How would that even work?

Apparently, the mantises are making it work. Researchers set out to collect and compare every single report they could find of a mantis eating a bird. They figured they’d find a few. Maybe one or two mantis species had figured it out.

One or two species had. As had another one or two. And another ten after that. All in all, the researchers discovered 147 accounts of bird-eating mantises from 12 different species. And this wasn’t some exotic local custom, either; the mantises were grabbing birds in 13 different countries, and on every continent except Antarctica (and that may only be because there are no mantises there).

The paper’s authors were floored by their own findings. "The fact that eating of birds is so widespread in praying mantises, both taxonomically as well as geographically speaking, is a spectacular discovery," lead author Martin Nyffeler of the University of Basel said in a statement.

Of course, we’re not talking about big birds here. Of the 24 bird species spotted in mantis mouths, many were hummingbirds. But hummingbirds are no joke, either. Males competing for territory and mates habitually stab each other in the chest. While hunting, they can snap their beaks shut in less than one hundredth of a second. They may be pretty, but they’re hardly helpless.

Nyffeler and his colleagues note that the bugs’ bird eating is more than a party trick. Farmers and gardeners regularly release mantises into the wild, relying on the insects’ appetites for pest control. But you can’t tell a mantis what to do. It might not want to eat your bugs, especially if there are juicy birds nearby. And birds aren’t doing so great right now. We should probably give them a break.

Still thinking of unleashing your own mantis horde? The authors advise “great caution.”

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.
