Snaky
smells help squirrels stay safe
WASHINGTON
(Reuters) - It's scary being a little, tasty squirrel, but some species of the
rodents have come up with an intimidating camouflage -- snake smells.
California
ground squirrels and rock squirrels chew up rattlesnake skin and smear it on their
fur to mask their scent, a team at the University of California Davis reported.
"They're
turning the tables on the snake," Donald Owings, a professor of psychology
who helped lead the research, said in a statement.
Barbara
Clucas, a graduate student in animal behaviour, watched ground squirrels and rock
squirrels chewing up pieces of skin shed by snakes and then licking their fur.
The
scent probably helps to mask the squirrel's own scent, especially when the animals
are asleep in their burrows, they wrote in the journal Animal behaviour.
