WILDLIFE IN FOCUS
with ecologist Sue StevensYou 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.You 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.
