We found a path down to a reservoir. Surprisingly, there weren't any waterfowl or shorebirds in sight. Titmice and Chickadees sported in the pines, and we saw two Downy Woodpeckers chasing each other.
I was expecting nesting warblers, but didn't see any. Perhaps we were in the wrong place, or not looking in the right habitat. We'll be better prepared when we go back next year.
There were chipping Sparrows at the edge of the parking lot when we returned, an adult and a streaky-breasted juvenile.
