 What does a bookworm have in common with a black-tufted marmoset? They both like a little quiet. Or so say scientists in the Royal Society journal Biology Letters. 

 
As urban areas continue to expand, their human inhabitants spread all sorts of pollution: air pollution, light pollution, even noise pollution. Each of these environmental encroachments affects the survival and behavior of local wildlife. And monkeys are no exception. 
 
Scientists in Brazil were studying how marmosets in a city park cope with ambient noise. And they found that the monkeys tend to settle down in whatever part of the park is most quiet. On weekdays, the marmosets steered1 clear of the roar of traffic, and on Sundays they shunned2 the clamor of visiting crowds. They dodged3 all the din4, even when moving meant that they had to leave behind the places that offered them the most food. 
 
It could be that the monkeys are just skittish5 when it comes to unwelcome sounds. Or maybe they can't hear what their friends are saying when it gets too loud. Either way, next time you see a cute little marmoset, forget "oooh" or "awwww" or "ee-ee-ee." Try shhhh.
