The birds are unseen at the beginning of the recording. They land near to one another in a large tree and visual contact is established. One of the birds flies to another branch approx. 30 ft. directly above the microphone but does not vocalize. Visual contact is lost with the second bird at this point.
The birds are moving laterally across the microphone and towards it from one tree to another.
