Two hummingbirds on one of my garden trellises. I made the trellises from 16’ cattle panels, and use them to grow beans, pumpkins, and grapes. And of course some clematis and morning glories.

Two small birds are perched on a metal garden trellis in front of a wooden fence with greenery in the background.

Moonrise Cafe, Fargo, ND. Handmade blueberry coconut poptart. Is this health food? Maybe not the kind a medical professional would prescribe but it sure feels good to eat it.

Serendipitous Discovery: https://davoh.org/2026/07/08/serendipitous-discovery.html

A wooden bookshelf filled with various books is situated indoors in front of large windows revealing lush green foliage outside. I took this photo in Puntarenas, Costa Rica. The shelves are full of discoveries of others; the forest beyond is full of potential for those who would discover more for themselves.

A spacious, well-lit library features wooden beams, multiple bookshelves, comfortable seating areas, and study tables arranged in an organized and inviting manner. St John’s College Meem Library in Santa Fe, New Mexico. This was the site of many of my serendipitous discoveries as a graduate student, and it continues to be the place I most want to return to on each return visit to my alma mater.

A small squid with a mottled brown and green body is resting on the ocean floor amidst sandy and rocky terrain. This Caribbean reef squid floated beside me while I was teaching ecology on one of the barrier islands in Belize a few years ago. We both held nearly motionless, eyeing one another. I was struck with wonder at what its changing colors might mean. Was it communicating with me? Warning other squid about me? Camouflaging itself? Do the chromatophores act as sensory organs, allowing it to use its skin to better perceive the world? &10;&10;I also wonder what it thought of me.

Adding to pages as I travel. We are back home, and with the tiring parts of travel behind us I’m looking back over the sketches I made in Vermont and Maine. So good to see old friends, our old home state, our alma mater, and the familiar landscapes of forests, lakes, and mountains.

Two sketches depict a common loon and a mountain landscape with handwritten text describing the scenes and dates.
