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.
JUMPING BAIL: The democracy advocate said made the decision after ‘considering the situation in Hong Kong, my personal safety, my physical and mental health’ Hong Kong pro-democracy activist Agnes Chow (周庭), who was jailed over her role in massive 2019 protests, on Sunday said she had moved to Canada and would not return to meet her bail conditions. Chow was one of the best-known young faces of the 2012, 2014 and 2019 protest movements against Beijing’s increasingly authoritarian rule in Hong Kong. She spent about seven months behind bars for her role in a protest outside Hong Kong police headquarters in 2019, when huge crowds rallied week after week in the most serious challenge to China’s rule since Hong Kong’s 1997 handover. On Sunday
TAKING STOCK: It was not yet clear how damaging the espionage, dating to 1981, has been, as authorities are still assessing the situation, the State Department said A former US ambassador to Bolivia has been arrested and charged with spying for Cuba over a 40-year span, the US Department of Justice announced on Monday, detailing a shock betrayal by a suspect who called the US “the enemy.” US Attorney General Merrick Garland laid out the allegations against Victor Manuel Rocha, a onetime member of the White House’s National Security Council now accused of using his positions within the government to support Cuba’s “clandestine intelligence-gathering mission” against the US. The charges against Rocha, 73, expose “one of the highest-reaching and longest-lasting infiltrations of the United States government by a foreign
DARK WARNINGS: If Trump survives his court trials, neither the Supreme Court nor the US Constitution could stop him from becoming president for life, a ‘Post’ column said Former US president Donald Trump on Tuesday declined to rule out abusing power if he returns to the White House after Fox News host Sean Hannity asked him to respond to growing criticism of his rhetoric. The Republican presidential front-runner has talked about targeting his rivals — referring to them as “vermin” — and vowed to seek retribution if he wins a second term for what he argues are politically motivated prosecutions against him. As Trump has dominated the Republican presidential primary, US President Joe Biden has stepped up his own warnings, contending that Trump is “determined to destroy American democracy.” “Under no
