影音備註
There's a Tropical Mockingbird singing in this recording (the loudest bird), but the sheep-like bleating noises were made by Lesser Nighthawks pursuing each other in flight about 1-2 m off the ground. Later on in the recording, the pulsating song can also be heard. In the second half, some high-pitched Stripe-headed Sparrow noises can be heard.
觀察細節
Much vocalizing every time two birds flew synchronous close together. Since all birds that engaged in these spectacular low flights at eye level had white wing bands, I assumed these were males performing courtship for watching females? [Note: the BNA account describes these courtship flights as males closely pursuing females, but at least on one occasion — and I think most of the time — I observed two males flying together like that.] I also heard what sounded like singing males in the background (the long, pulsating medium-low series of calls). The flight calls, which I recorded, were clearly from the nighthawks and were quite different from that pulsating long cal.
