She looks a trifle upset over something she's looking at on the ground? I don't know in particular what cardinals eat, so I'm not sure what she's doing but if she lived anywhere near my house, there would be a dozen cats from the neighborhood checking her out :(
"The artist is a receptacle for emotions that come from all over the place; from the sky, from the earth, from a scrap of paper, from a passing shape, from a spider’s web." Pablo Picasso
Now PJ, of course she's upset - she's an adolescent female. She was probably rolling her eyes with a big "WHATevr" at poor Mike just seconds before this shot. That's just the way they are.... :D
