Various vocalizations by two common poorwills. This recording includes soft sounds that may have been wing flapping. Possible mating?
Detalles de la observación
Initially I heard one poorwill, so I stepped outside and recorded it. Then I went back inside for a few minutes. After hearing other, different sounds I stepped outside and obtained the 2nd, 3rd, and 4th recordings below. While recording the 2nd and 3rd recordings, I noticed that two birds were vocalizing from different directions. Then the louder flight calls/poor-will-o calls moved to the location of the softer calls. I heard several series of softer, non-vocal sounds that I interpreted as either wing beats or sand gently falling down the slope while the birds were possibly mating, moving, and dislodging the sand. Later Curtis Marantz suggested those might be sounds of wing clapping, which would indicate a courtship display. The first file (ML145292331) has vocalizations from only one bird. Files ML145292431 and ML145292461 have two birds. Both of those recordings were extracted from the same original file--I cropped out a number of seconds of handling noise and my voice dictating notes. ML145292591 features vocalizations from only one bird. For the latter file, I turned on a light and verified that only one bird was present. After obtaining recording ML145292431 I switched on a light and verified two pairs of eyes but by then the birds had separated by about 5-8 meters. In nearly 3 1/2 years of hearing poorwills in this area, this is the first time there have been two so close simultanously. Locations were on the roadcut on the north side of houses at 1465 and 1475 E Loma Alta Drive. The recordings below are arranged in chronological order.
