I drove by the Spit yesterday and briefly stopped. I wanted to check out the woods behind the parking lot. I took a quick walk in and heard a chirping that I haven't heard since last spring. I couldn't locate a bird, but I heard two songs that sounded like the happy warbler song.
Today, I was at the Spit again. Near the parking lot (this time, on the east side of the road in front of the parking lot), i heard the same cheery call. All I could spot were two chickadees, but they weren't making the call.
Later on, a birder told me she swore she was a black and white warbler in the Spit.
