The next day, I returned to the Ajo Mountain Loop. The Estes Canyon – Bull Pasture Trail is described as a recommended spot for “owling,” particularly in the early morning. It doesn’t specify which owl species. The National Monument is home to the Elf Owl, a small owl that uses holes in cacti as its nest, but since there don’t seem to be many large cacti here, it might be a different species.
Unlike the Desert Trail from the previous day, the canyon is quite lively. However, although I could hear what seemed to be owl calls, they were still not easy to spot… Even so, I encountered many creatures, so choosing Estes Canyon was the right decision.
I took a break near the highest point of the trail. Other than the sounds of birds and insects, the world was almost completely silent. It took about 35 seconds of fly buzzing to realize how quiet it was.
As a bonus, though the Saguaro Cactus is long-lived, (naturally) some do eventually wither.
The two-day, one-night trip exceeded my expectations. Choosing the Organ Pipe Cactus National Monument was a great decision.
