As it turned out, I ended up not seeing that many sparrows yesterday. I saw a small flock of crisp-looking Savannah Sparrows in one of the butterfly gardens. Plus there were some Song Sparrows and White-throated Sparrows around. But the fields seemed to have very little sparrow activity at all.
There was a bit more activity in the wooded and edge areas, where I saw a lot of Yellow-rumped Warblers. I saw my first Yellow-bellied Sapsucker of the fall, as well as a Blue-headed Vireo, Ruby-crowned Kinglets, and some Palm Warblers. Towards the end of the morning, I heard and then saw two Ring-necked Pheasants along the entrance road into the preserve.
