Thin clouds combined with fog made for a solid gray sky, but there was plenty of avian activity on the trail this morning. I arrived around 9:00, and had logged 19 species on the downstream trail before reaching the picnic table. I then added another 13 species farther downstream and on the Glenthorne Loop trail, and finished with 4 additional species hiking upstream to the park benches, including my first-of-year Louisiana Waterthrush and my FOY chipping Sparrow, bringing my morning total to 36 species.
Other highlights included a male and a female American Kestrel at the end of the downstream trail, two Swamp Sparrows, and lots of birds gathering nesting materials.
