I birded at Seneca this morning, April 2, and was surprised to find a prothonotary warbler, two northern parulas, and one Louisiana waterthrush. All of these were seen on the toepath, just past the turning basin (where a narrow stream cuts perpendicular from the left side of the path to the river--if you're facing north). According to the "Yellow Book," the prothonotary would almost be record early (3/31 is shown as the early date), and the parulas would be considerably early. I also saw two to four blue-gray gnatcatchers. Does anyone remember seeing prothonotaries this early? I've looked back in my notes and don't think I've ever seen one the very first week of April.
