People can tell how other people
are feeling by the sounds they make and now, new research from the University
of Alberta shows that may also apply to different animals.
"The idea is that some
species (those that are vocal learners) can understand other species'
vocalizations," explained psychology Ph.D. student Jenna Congdon, who led
a new study that showed both humans and black-capped chickadees can detect
intense emotions such as fear or excitement in other species.
"For instance, a songbird is
able to understand the call of distress of a different type of songbird when
they are in the presence of a predator, like an owl or a hawk. Or, for example,
if your friend scared you and you screamed. Both of these are high-arousal
vocalizations, and being able to understand what that sounds like in a
different species can be very useful."
