Song sparrow has been singing every day, often from the $%^&* tree outside the yard

 I guess that %^&*(# tree that was planted a few years ago and which I fear will start eating away at my yard's already-limited sun, is coming in handy for something.  Mr. song sparrow (I assume it's a he?) has been singing almost every day, and sometimes comes into the yard hopping along the ground for snacks.
