I guess the American Robin could be a Stepping Razor. I mean its a bird that gets highly defense of its breeding territory during the summer and less social.
Also they will flock fermented Pyracantha (firethorn) berries, eating them in sufficient amounts until they become drunk to the point of falling over. Capable of eating both berries and insects, with the ability to hear worms unground.
Yet these Robins live at the airport overlook, so now feed off the left overs of our processed food choices.
