A journal can be a rumination, a venting, a hymn of praise. Or it can be a list, an outline, a series of observations.

For the last two days I’ve been reading the diaries of the late Ira N. “Gabe” Gabrielson, first director of the U.S. Fish and Wildlife Service and noted conservationist.

In 1966, Gabrielson sold his home, garden and lovely bamboo-fringed pond to the Fairfax County Park Authority. He and his family continued to live in the house for years, but after his death the property became a tiny tucked-away park called Gabrielson Gardens. I stumbled upon it this fall and have been interested in learning more about Gabrielson ever since.

This week I visited the Smithsonian Archives and began to read Gabrielson’s diaries. There is much to learn about the man. But one thing struck me immediately: In his journals he lists the vegetables he harvested and the birds he spotted. I think about the thoughts, ideas and feelings I write in my own journal. It’s another model. Both are time-honored. But this morning, after my usual entry, I noted that two bluebirds and a red-headed woodpecker perched on the deck railing and nibbled some suet.
