Still digging through old files on a rainy day. This little Pine Warbler was very vocal, especially when I used a bit of audio to entice him onto a lower branch. The species has blurry streaking on its sides, but this guy looks especially blotchy. Molting? Or perhaps the mottled lighting coming through the branches? Taken in upstate New York in May of 2016.
