Why are toads puffing up and spontaneously exploding in northern Europe?
It began in a posh German neighborhood and has spread across the border into Denmark. It has left onlookers baffled, but one German scientist studying the splattered amphibian remains now has a theory: Hungry crows may be pecking out their livers.
"The crows are clever," said Frank Mutschmann, a Berlin veterinarian who collected and tested specimens at the Hamburg pond. "They learn quickly from watching other crows how to get the livers."

So far, more than 1,000 toad corpses have been found at a pond in Hamburg and in Denmark. But the pond water in Hamburg has been tested, and its quality is no better or worse than elsewhere in the city. The remains have been checked for a virus or bacteria, but none has been found.
Based on the wounds, Mutschmann said, it appears that a bird pecks into the toad with its beak between the amphibian's chest and abdominal cavity, and the toad puffs itself up as a natural defense mechanism.
But, because the liver is missing and there's a hole in the toad's body, the blood vessels and lungs burst and the organs ooze out.
As gruesome as it sounds, it isn't actually that unusual, he said.
"It's not unique -- it's in a city area, and that makes it spectacular," he said. "Of course, it's something very dramatic."
There have also been reports of exploded toads in a pond near Laasby in Denmark.
Local environmental workers in Hamburg have described it as a scene out of a horror or science fiction movie, with the bloated frogs agonizing and twitching for several minutes, inflating like a balloon before suddenly bursting.
"It's horrible," biologist Heidi Mayerhoefer was quoted as telling the Hamburger Morgenpost daily. "The toads burst, the entrails slide out. But the animal isn't immediately dead -- they keep struggling for several minutes."
Hamburg's Institute for Hygiene and the Environment regularly tests water quality in the city, and found no evidence that the toads were diseased. The institute even ruled out that the toads were suffering because of a fungus brought in from South America.
Other theories have been that horses on a nearby track infected them with a virus, or even that the toads are taking the selfless way out -- sacrificing themselves by suicide to save others from overpopulation.
Could hungry crows be a reasonable answer?
"We haven't seen that. It might be, it might not be," institute spokeswoman Janne Kloepper said.
Local officials in Hamburg were advising residents to stay away from the pond dubbed "the death pool" by German tabloids.
SEEKING CHANGE: A hospital worker said she did not vote in previous elections, but ‘now I can see that maybe my vote can change the system and the country’ Voting closed yesterday across the Solomon Islands in the south Pacific nation’s first general election since the government switched diplomatic allegiance from Taiwan to Beijing and struck a secret security pact that has raised fears of the Chinese navy gaining a foothold in the region. The Solomon Islands’ closer relationship with China and a troubled domestic economy weighed on voters’ minds as they cast their ballots. As many as 420,000 registered voters had their say across 50 national seats. For the first time, the national vote also coincided with elections for eight of the 10 local governments. Esther Maeluma cast her vote in the
Nearly half of China’s major cities are suffering “moderate to severe” levels of subsidence, putting millions of people at risk of flooding, especially as sea levels rise, according to a study of nationwide satellite data released yesterday. The authors of the paper, published by the journal Science, found that 45 percent of China’s urban land was sinking faster than 3mm per year, with 16 percent at more than 10mm per year, driven not only by declining water tables, but also the sheer weight of the built environment. With China’s urban population already in excess of 900 million people, “even a small portion
UNSETTLING IMAGES: The scene took place in front of TV crews covering the Trump trial, with a CNN anchor calling it an ‘emotional and unbelievably disturbing moment’ A man who doused himself in an accelerant and set himself on fire outside the courthouse where former US president Donald Trump is on trial has died, police said yesterday. The New York City Police Department (NYPD) said the man was declared dead by staff at an area hospital. The man was in Collect Pond Park at about 1:30pm on Friday when he took out pamphlets espousing conspiracy theories, tossed them around, then doused himself in an accelerant and set himself on fire, officials and witnesses said. A large number of police officers were nearby when it happened. Some officers and bystanders rushed
HYPOCRISY? The Chinese Ministry of Foreign Affairs yesterday asked whether Biden was talking about China or the US when he used the word ‘xenophobic’ US President Joe Biden on Wednesday called for a hike in steel tariffs on China, accusing Beijing of cheating as he spoke at a campaign event in Pennsylvania. Biden accused China of xenophobia, too, in a speech to union members in Pittsburgh. “They’re not competing, they’re cheating. They’re cheating and we’ve seen the damage here in America,” Biden said. Chinese steel companies “don’t need to worry about making a profit because the Chinese government is subsidizing them so heavily,” he said. Biden said he had called for the US Trade Representative to triple the tariff rates for Chinese steel and aluminum if Beijing was
