The glory days of springtime come fast and fleeting. Miss the trillium, and you have to wait a whole year to see it again. Migrating birds come, feed, and leave again while we sleep or work or are otherwise distracted. There never seems to be enough time in my spring; no way to capture it all before the symphony of greens gives way to summer. Still, I’ve managed some quick sketches in the woods and I was fortunate to be home when a pair of rose-breasted grosbeaks showed up at the feeder.
