Call me: female zebra finches prefer their mate’s call

Social interactions are highly sought-after and rewarding in many animals... Even when social interactions involve only one of our senses, they are still rewarding. For example, we like looking at photos of our friends on Facebook, or hearing the voice of a faraway relative via telephone. It’s the same with other animals; not only is socialization rewarding and can be used as an incentive for learning, but just the sights, sounds, and even smells of others are also rewarding. Hernandez et al. explored this concept with female zebra finches, who were shown to prefer the calls of their mate....
