Crows:
These are the fifth smartest animals on the planet. They
gather nuts and place them on roads for passing cars to crack the
nuts. And then they wait for the traffic light to change and pick the
nutty snack. They use specific dialects to communicate in elabo-
rate populations. They play games and tricks on one another and
known to be intelligent than primates. They are born with tool
making ethics and are crafty critters as they fashion tools from
twigs, feathers and other bits of debris to snare food from
hard-to-reach places. They can count, distinguish complex
shapes and perform observational learning tasks.
Crows are crafty critters: They fashion tools from twigs,
feathers and other bits of debris to snare food from
hard-to-reach places. A crow named Betty, uses a
straight wire she bent into a hook to retrieve food
from a tube. The birds are born with a tool-
making ethic, but they hone their craft by
watching their elders, a sign of higher
intelligence. Ravens, a type of
crow, have even been shown
to manipulate the outcomes
of their social interactions
for added protection and
more food.
Pigs:
These are the sixth smartest animals and
are highly intelligent animals. They adapt to
a variety of ecological conditions. They are
flexible and can be trained easily. They roll
in mud to keep their body cool.
They are perhaps the smartest, cleanest
domestic animals known - more so than
cats and dogs, according to some experts.
But pigs don’t have sweat glands, so they
roll around in the mud to stay cool. A sign
of their cleverness came from experiments in
the 1990s. Pigs were trained to move a cursor
on a video screen with their snouts and used
the cursor to distinguish between scribbles
they knew and those they were seeing for the
first time. They learned the task as quickly as
chimpanzees.
