    Equipment Note

At approx. :02, two light morph Round Island Petrels fly past the microphone in the "paired" formation. At approx. :22, the Black Winged Petrel can be heard (unseen). At approx. 1:10 two Round Island Petrels (both light morph) fly past the microphone in the "paired formation". At approx. 1:15, a single Round Island Petrel vocalizes unseen from the group of nest sites described in RRN JPE-MU2010-178. (Note: Upon completion of this recording, an inspection was made of the nesting sites which revealed an intermediate phase bird on nest #24, a dark phase bird on nest #DH, a dark phase bird on nest #8, and a fourth bird (unseen) which flew off before identification).
