I stayed close to home today, and did a morning hike under cloudy skies and an afternoon hike under bright and sunny skies. I ended up with at least 36 avian species, and saw a fox on the trail on my morning hike. At one point on my morning hike, I saw a flurry of activity. There were Ruby-crowned Kinglets, Yellow-rumped Warblers, at least one Black-throated Green Warbler, at least one Common Yellowthroat, and two species that I saw briefly and was able to get poor photos, but would appreciate opinions as to what they were.
Great Blue Heron
Black-throated Green Warbler
The first unknown warbler has a yellow head with a dark eye-line, a grayish back, and a white vent. My first impression when I saw it was a Magnolia Warbler, but I only saw it for an instant, and there is no eye ring, which rules out Magnolia and Nashville Warblers as possibilities. A Blue-winged Warbler is a possibilty, but it doesn't really look like that species, either. It is most likely a Black-throated Green Warbler, and the grayish coloring is an artifact.
The second unknown species shows a buffy underside and white spots on its tail. It probably is a Yellow-rumped Warbler, but I don't see any breast streaking.
Birds were easier to photograph in the afternoon sunlight. I did see one mystery bird that popped up in front of me for just an instant. It looked larger than a warbler - closer to the size of a Mockingbird, but it had a creamy white breast with dark streaks and a brown back - my first thoughts were either American Pipit, but the bird was about 8 to 10 feet above the ground, or a Louisiana Waterthrush, but this species should be gone by mid-September.
