In the brush nearby, there were several other sparrows. Some of them were Song Sparrows, but there were also a Chipping Sparrow, a Field Sparrow, and two Savannah Sparrows. One of those Savannah Sparrows had what I think is the brightest yellow supercilium I have ever seen on that species. Chipping Sparrows are now singing all over the park, and there are even some Dark-eyed Juncos left.
Aside from the sparrow show, I saw my first Blue-headed Vireo and Northern Parula of the year yesterday.
