Birds as friendly faces

A birder’s brain responds to photos of familiar bird species in a way that is, neurologically, “strikingly similar” to the way that anyone’s brain responds to photos of familiar human faces (Tanaka & Curran 2001): birders seem to use a similar strategy to recognize birds as everyone uses to recognize people they know. If you are a birder, this probably isn’t surprising; certainly, to me, recognizing a bird species feels similar to recognizing a friend. And it isn’t only birders: the study also looked at “dog experts”—which I did not know existed before I read this—and found the same pattern when those experts looked at photos of dogs. If you are passionate about models of cars or architectural styles or garden flowers, I wouldn’t be surprised if you experience the same thing.

(Bafflingly, the study reports that the photos it showed to the birders included “the robin, sparrow… oriole… [and] hawk,” none of which are actually individual species. Which sparrow, guys? Didn’t you talk to your birders at all while you were studying their brains?)
