Sparrow or finch

in the Fill I come across a sparrow-like bird, I don't know what it is. It's not particularly wary, and let's me look at it. In fact, it turns it's back so I can see the color pattern, the long tail, hops around, kicks at the ground a bit with it's feet, eats some bugs, then in front of me, starts eating off bits of dandelion leaves. It wants me to figure it out. It has a little gold-coloring on top of head. Eventually, I scare it off a few feet by taking it's picture. I think it must have been the loudness of the shutter.  I look it up. I think it must be a golden-crowned sparrow. It's either a juvenile or one in winter plummage.  I think the biggest clues were the color pattern on the upper back and the fact that it started to eat dandelion leaves.  I've never seen a song bird do that before, ducks, geese and chickens do that all the time, given the opportunity.
