We can talk a lot about ravens for a long time and certainly with enthusiasm, as these birds are so strikingly tall intelligence (for birds), which sometimes seems – they are in this regard not inferior to man. Clever bird, you will not say anything!
However, unlike humans, crows have a mass abilities that make their life much more free and attractive. For example, they can fly, even using this advantage over us is very clever, and sometimes funny. For instance, a raven can calmly ride on the back of an eagle – just like that, for fun …
But there are much more amazing things that they can do. crows. Say they have a great digestive system, and because they can eat almost anything – from small animals, to food waste and even carrion or parasites, pecking them, for example, in bull-bantengom (beautiful symbiosis of the mighty animal and clever bird). It is such an amazing breed of these black-winged birds – Corvus orru – found in tropical Australia These clever birds can eat even the most poisonous amphibians in the world – toads aha.

In Rhinella marinus (as this toad is called in Latin) in nature almost no enemies, since she is endowed with the ability secrete the strongest poison bufotoxin (causes instant paralysis hearts), and not only highlight, but still aptly and relatively far shoot them at your victim or enemy. Therefore with this creepy nobody wants to get in touch, but not the local endemic raven family.
The Australian Raven, it turns out, is smart and wary hunter who managed to develop a unique tactic that allows him to eat tasty meat of toads aha, not at all risking being poisoned by this monstrous predator. No, of course, Corvus orru to some extent risk, but … who does not risk, that, as they say in people don’t drink champagne (apparently, this bird has heard this more than once statement from the mouth of a person, and made a corresponding conclusion).
First, the raven grabs a toad, and instantly, for the most safe places – superciliary arches or limbs, which allows him to turn his “dangerous dish” and roll the victim on the ground to until she dies. After that, the bird skillfully (gently and almost unmistakably, see about this video) pecks everything nutrient parts of the body of the toad, without touching its poisonous glands. Here man, tell me, would be able to do this? Never!
Note that in Australia, the toad aha has long been considered dangerous. an invasive species among amphibians, however these creatures here are so a lot, and the number of smart and dexterous ravens is very small, which so far, the latter simply cannot solve this problem. That’s the truth characteristic for human society: the mind is good, but poisonous language is much better …
