We went to Lagunitas, California, to the lovely Leo Cogan Fish Viewing Area, and eventually saw a large female coho on her redd, redd being the word for the nest area she excavates in the gravel, where she lays her eggs. In clouded water, her whitish tail gleamed.
At St. Mary's Pub to celebrate the 800th iteration of David's Pointless Minute, I told a wildlife-aware friend about this. I used the word nest. He said the correct term was redd. I agreed, acknowledging that I had talked down to him by using simpler terminology. He alleged that he was offended. I alleged that in that case my work was done.
Salmon: always a contentious subject.
