WILDLIFE IN FOCUS

with ecologist Sue Stevens
Raven1.jpgYou mightn’t know this fact but Ravens are in fact native.

Ravens are all closely related and descended from one common ancestor.

When it comes to intelligence, these birds are as clever as chimpanzees and dolphins.

Many ravens got the food on the first try, some within 30 seconds.


In the wild, these birds have pushed rocks onto predataros to keep them from climbing to their nests, and played dead beside a carcass to scare other ravens away from a delicious feast.
If a raven knows another raven is watching it hide its food, it will pretend to put the food in one place while really hiding it in another.
Since the other ravens are smart too, this only works sometimes..


As Sue mentioned, Ravens recognise people carrying guns, they avoid traps, and they follow and harass large predators for food, or follow trappers and steal bait from traps.
The best fact of all is Ravens have learnt to turn road-killed cane toads over and eat them from the belly, thus avoiding the dorsal poison glands.
Raven.jpgYou might this hard to believe but did you know that in captivity, ravens can learn to talk better than some parrots.
They also mimic other noises, like car engines, toilets flushing, and animal and birdcalls.They’re also as good a flyer as falcons and eagles.
Turns out that Ravens' family tree evolved in Australia.
They then radiated out into the rest of the world where they proceeded to become the world's most diverse and successful group of birds.
