    Equipment Note

First segment: The bird flies past the microphone while chasing a Round Island Petrel and vocalizing.

Second segment: The bird exhibits a similar behavior as mentioned in the previous recordings. It attempts to "chase" several Round Island Petrels with a similar result in the Round Island Petrel almost immediately breaking away from it. Towards the end of the recording, the Black Winged Petrel manages to "chase" one of the Round Island Petrels for approx. 15 seconds while vocalizing. The Round Island Petrels can be heard vocalizing near the Black Winged Petrel and in the distance.

LNS: 100HZ AUHipass filter applied to first and second segments in soundBlade.
