This warbler clearly shows a bright yellow face and strong wingbars. Upon closer inspection, this bird appears to have a dark throat. These characteristics fit a Black-throated Green Warbler.
This birds appears to be black with and orange belly, however, the photo was taken just at sunrise. When the sun is low, be careful that the colors are not being altered before making a positive identification. Although the underside may appear orange, it is actually white. The pattern on black on the face and the band down the side are characteristics of a male Black-throated Blue Warbler.
At first, this warbler had me stumped. I knew it was a warbler based on flight, tail pattern, and flight call (which I was unfamiliar with), but I could get it down to species. After studying the photo and consulting a few friends, I have come to the conclusion that this is a Cape May Warbler based on the streaking on the underside.
Note the face pattern and the streaking on the side of this Cape May Warbler.
This male Hooded Warbler is unmistakable in flight. The yellow body and face and the black chin really stand out. This guy was uttering its flight call, which is a distinct buzz, similar to the flight call of a Common Yellowthroat.
This warbler shows a yellow underside and an all-dark tail. These characteristics, combined with other observations in the field, help identify this Tennessee Warbler.
Many field marks are visible on this Northern Parula, including the bluish head, strong white wingbars, and yellow throat.
