While stopping to look out over a vista en route to a park in central Argentina, I noticed this very tame Chiguanco Thrush hanging out around the parking lot. Clearly the bird had been fed a bunch, since it was so tame around humans. But when I didn't offer it any food, he flew to a nearby stump, puffed its feathers and gave me the look I have photographed here. I definitely ruffled someone's feathers that morning.
