In the woods on the far side of the lagoon I found "first of year" Tree Swallows which were very vocal and chasing each other on and off perches in the tallest snags.

Directly below all of this dogfighting I heard a rustling in the leaf litter. Initially discounting it as another one of the many American Robins that kept hopping across the trail it seemed a little too quiet and a little too close. With a little persistence I made out the following spectacularly helpful view.
Given recent reports of White-crowned Sparrows, I played that call note on my iPhone to no response. The call of a White-throated Sparrow elicited a very different reaction - the sparrow shot up onto a branch over the trail. As if to say, "I hear your call and raise you" he performed several refrains of "Oh-sweet-Canada-Canada-Canada" and then returned to foraging in the undergrowth. You can hear the call at Xeno-Canto.
