On 9/21, I heard the distinctive continuous dry buzz of this species, which I had never before heard in Ithaca. I tracked the call down to a lone male in a clump of ornamental grass on Central campus (where there were also several N. ensiger singing), but he escaped into the grass. Immediately afterward it began to rain, and then temps went down to 50s and 60s over the next several days. I figured that the rain and cold weather would have kept him in his grass clump, so when the weather turned warm again I went back to the site, and sure enough he was singing again. Unfortunately he lost both his hind legs during capture. I then wandered around a bit more and found a second lone male on another part of campus:

These are not known to breed in Ithaca, so I suspect that these two males were either brought in on ornamentals, or flew in on their own.
