    Equipment Note

The birds are looping in 360 degree patterns over the palm savanna mentioned in RRN JPE-MU2010-258 and occasionally "pairing" with one another. The birds are occasionally flying below the savanna and out of visual contact. At approx. 1:50, two birds are flying in the "paired" formation. A third bird approaches them and the following bird flies away allowing the third bird to begin following the lead bird. It vocalizes while doing so. During the recording, approx. 3-4 individuals are occasionally slowing themselves while vocalizing over the savanna looking as if they are attempting to land.
