Began the day with some photography in the garden and then did some sketching and painting from my photos while waiting in my doctor’s office. Enjoying the bees and flowers while the weather allows, and enjoying the garden while it still exists.
A detailed drawing shows a bee approaching a purple New England Aster flower, accompanied by handwritten notes and a color palette.

Three bees on a sunflower. Two of them are Agapostemon virescens, I believe. The third is fuzzy. (Not a scientific description but I can only claim so much expertise.)
A vibrant yellow sunflower with a dark brown center is visited by a large yellow-and-black blurred bee and two metallic green bees on its petals.

I’m hosting a series of workshops for faculty this fall on difficult conversations. What have you found helpful when you disagree with someone (friend, colleague, family, neighbor) about something that feels like a truly important matter?

Part of the phenology calendar in our kitchen. Are there species you watch for where you live?
A whiteboard notes the fall phenology dates for 2026, including the last and first sightings of hummingbirds, Maximilian sunflowers, New England asters, monarchs, and Bombus pennsylvanicus.

As wonderful as e-books are, with each passing day I have less and less interest in large corporations owning my access to media, and renting me that access in a way that can be withdrawn or altered at their discretion.

Buy physical books. Annotate them. Keep the best ones close at hand and return to them. Buy extra copies to give away.

There’s a good chance that someone out there would benefit from a word of gratitude. Take a moment to thank someone today. It costs so very little, and the ROI on gratitude is both large and long-tailed.

Y’all, get outside. If you live near me you know the migrations have begun. I drove under a flock of pelicans the other day. Monarchs are on the move. Green darners, too. It’s such a beautiful world. Go have a look.

Lots of migration is starting to happen around us. The monarchs and green darners are appearing in greater numbers. The hummingbirds are at the flowers more often, filling up for the long trip ahead.

It works amazingly well. So many medications sound better if they’re said with a Klingon inflection.
