New Delhi: Turns out, humans aren’t the only creatures that get frustrated and annoyed. But, squirrels do too.

Inspired by Darwin, Delgado was intrigued by squirrels’ emotional worlds, says a report produced by KQED.

Though fox squirrels chatter their teeth, they don’t really make any facial expressions like we do to signal our sadness, anger or surprise. The way to tell what they’re feeling, researchers have found, is to watch their tails, adds the report.
