In the ‘Lost Forever’ series of articles, The Nature Nook will be looking at animal species that have become extinct in the past 500 years or so. Now, I should first point out that extinction is a perfectly natural process. It has always taken place throughout the history of life on Earth. Just as every individual that is born will die, every species that evolves will eventually become extinct. In fact, some 99.99% of all species that have ever lived on our planet are now extinct.
The weasel is small. Really small. Much smaller than most people realise. It is not only the smallest mustelid, it’s also the smallest carnivore in the world. Growing to between 13 and 26 cm in length and weighing as little as 25 grams in some cases – about the same as an AA battery – it is a mere 0.0025% of the weight of the planet’s biggest terrestrial carnivore, the polar bear.
Welcome to Animal World Records! In this regular feature, we’ll be looking at animals that are the fastest, biggest or smallest of their kind. Those that fly higher in the air, or live deeper in the ocean, than any other. Those with the longest tongue, or the largest eyes, or the most number of legs.
As I covered in this article, there are many things around your home that present a physical threat to free-flying birds. But some of the dangers lurking in our four walls actually come in the form of silent or invisible threats that can be toxic to parrots, causing long-term health implications or even sudden death. Parrots are extremely good at hiding illness or injury, a trait they share with most other prey animals. Opportunistic predators in the wild will jump at the chance to pick off any member of the flock that looks more vulnerable than the rest, so if a parrot is unwell it pays to pretend as if they’re fine.
