Megan Friesen is a conservation biologist using bioacoustics technology to examine the breeding behavior of a secretive Pacific seabird called Buller’s shearwater, which breeds on the remote Poor Knights Islands, off of northern New Zealand. In this Field Notes segment, Friesen explains why bioacoustics techniques are critical to the research she's doing with the Northern New Zealand Seabird Trust, and she plays recordings of the birds from both of the main islands where it breeds.
