観察結果の詳細
At least 2 and possibly 3 Common Nighthawks making @300+ PEENT calls (once with a brief "rattle" at 2:10 min and @24 FOOMS (aka wing booms) in-flight, and courtship/mating calls made on the ground, including a set of 12 GROANs (at 9:57 min), wing flaps (at 10:04 min) at time of copulation (or attempted copulation) , and 9 DZIKs. Copulation (was witnessed 15-20 ft away from me. Recorded at the Overlook (410 ft) on Schoodic Head (435 feet). Perhaps flying as low as 375 ft as high as 450 feet -- so I was recording as fairly level position with them on the rocky outcrop. Other sound in background: lobster boats buoy bell surf on rocky coast Temperature @50 degrees, and partly cloudy skies. original file: B03h51m21s23jun2017y this file: trimmed, high pass filter (250 Hz), normalized to -3 dB
