    Equipment Note

In this recording, a single individual is flying in a "figure-eight" or partial "figure-eight" pattern with a nesting area in the center of the "eight". It flies over the nest site several times, slowing itself each time as it approaches. At approx. :26, a second bird flies close to the original bird and one of the two birds (undetermined) vocalizes. The mechanical sound of its wings can be heard as the bird comes to the outer edge of the "figure-eight" nearest the microphone.
