This has been the unofficial first weekend of spring -- sunny, balmy. The trees are still bare, probably still a little demoralized after our awful winter, but the rest of us are more than ready.
I always love watching the birds switching to their courtship clothes. The goldfinches are the most obvious, as they turn from a dull gold to bright yellow, but almost every species gets brighter, with sharper markings.
Compare this white-throated sparrow I saw yesterday with one from just a couple of weeks ago. He is ready to party!
