* Nature's Weirdest Events (2011 - 2013)

Chris Packham presents this documentary investigating unusual natural events, with the help of eyewitness accounts, scientists and footage of the occurrences.

Season 1

Part 1
In the first programme of this two-part series, Chris Packham takes us around the world to the scene of some of the weirdest natural events on the planet. With the help of footage taken by eyewitnesses and news crews, he unravels the facts and the science behind each phenomenon. There is the mysterious case of the car cocooned by caterpillars in Holland, and the baffling case of the exploding toads in Germany. In Switzerland a lakeside town is entombed in ice and a once in a lifetime storm turns Sydney, Australia crimson overnight. There are some disturbing plagues of mice and locusts and a swarm of ladybirds. And finally there are extraordinary strandings of starfish, crabs and whales. Chris tells the real story of the events behind the headlines and helps to explain what on earth happened.

Part 2
The second in this two-part series about the weirdest natural events on the planet features the incredible sea foam which turns part of the Australian coast into what looks like the world's biggest bubble bath. Plus there is a look at the mysterious death of thousands of sea birds on America's west coast, and the otherworldly phenomenon known as milky seas. Other strange events include thousands of birds falling from the sky in America, causing panic and predictions of the apocalypse among the residents, and the fish that fell from the sky in south London. And finally there is the story of the truly terrifying holes which open up in the earth's crust and swallow not only buildings, but in the case of a nature reserve in Florida, an entire lake
