Skinks Avoid Danger by Eavesdropping on Bird Alarm Calls
The Kalahari tree skink gains a lot from associating with sociable weavers. These small birds build big communal nests that offer skinks increased opportunities for basking and foraging. However, weaver nests also house a major predator of skinks, the pygmy falcon. How do Kalahari tree skinks manage living next door to their predators? The answer appears to be by eavesdropping on their neighbors.

Eavesdropping Squirrels
Eastern gray squirrels listen in to birds’ conversations for cues about nearby predator risk, according to a new study from Oberlin College. Researchers found that hearing casual bird chatter after a predator call signals safety to squirrels.
