You hear a distant bird song that seems to be coming from the line of trees at the other side of the field. Each short, unmusical phrase is repeated once. It sounds like he's saying "Look at me, look at me...up here, up here...in the tree, in the tree...to the left, to the left...no-no, no-no...now you got it, now you got it...focus, focus". Following his instructions, you are able to see that he is robin-sized or bigger, rusty-brown above, whitish with brown streaks below, and he has a long rusty-brown tail. What kind of bird is it?
