Is it a bird? No, it's a weasel
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Weasels are the world's animal high-jump champions, say scientists. A "predator Olympics" arranged by animal behaviour scientists at Victoria University, New Zealand, found that stoats can jump to heights of 1.9m (6ft 3in) - outleaping ships' rats, cats and possums.
The intention of the experiment was to decide how high and wide a barrier fence to protect a planned native bird sanctuary in the city should be. The experiments involved a group of local would-be predators in what the scientists were happy to call "ground-breaking" research.
Ships' rats managed 1.7m, feral cats 1.5m and - just missing the bronze - wild possums 1.2m. Eliminated early on were ferrets and Norway rats, defeated at 0.5m, while standard weasels and mice managed only 0.33m.
However, getting in to a sanctuary doesn't necessarily require jumping. Another contest pitted various tunnelling animals against each other - a challenge won by a Norway rat, which dug 0.6m along in the time limit. Charles Arthur
