Weekly Upland Sandpiper night flight call (nfc) activity detected from all five stations in the WNY acoustic monitoring transect. UPSA calls were automatically detected by Nighthawk 0.3.1 software operating from half-an-hour after sunset to 60 minutes before sunrise. W. Evans confirmed identity of the automatic detections and removed non-UPSA calls. UPSA nfc activity is the sum of all incidences of a correctly ID'd UPSA call that occurred at least two minutes from another UPSA call. Data in this graph is updated weekly through the end of Summer 2025.
