Let’s face it; some birds simply have more expressive faces than others. Oh, of course this is simply giving them human characteristics that are the accidental results of the markings on their feathers and the structure of their beaks. However even knowing this, it’s difficult to look at particular birds and not immediately assume that you understand what they’re thinking by the “look on their face.”
For example, take this male Rose-breasted Grosbeak image recently submitted to the Wingscapes Photo Gallery by Colin in Marietta, Georgia. Doesn’t it look as though he is clearly irritated?
