Believe it or not, there ARE other birds around besides geese and their babies. They're just much harder to photograph, what with that whole "up in a tree and totally backlit" thing. Sometimes they come down to tease me for a moment, letting me snap ONE out of focus shot before they're off. I think of these shots as less artsy and more just documentation of who's present in the park.
Here's a sassy little junco showing off a little-seen view of its tum:

And here's a goldfinch:

A common but shy towhee:

And something I haven't seen a lot of at the lake: a mourning dove:

It was closely following a pigeon, in what looked like a doomed love affair.

Sorry mourning dove, I know you two are both Columbiformes and all, but maybe try someone who's at least in your own genera.
