Picked up flying over the hut on an unattended recorder left running all night.

Juan Fernandez Petrel has an interesting history in the Chathams, at least two birds were regularly recorded on Rangatira from the mid 1980's to late 1990's but were never known to have bred. One of the birds was killed by a Brown Skua in 1999 and there had been no records since.

I got a recording of a weird laughing/cackling call on another night on the summit of the island which I think was also a JFP but haven't been able to prove it yet

bird-seen:no

playback-used:no

Pretty poor quality recording of the vagrant/pioneering Juan Fernandez Petrel on Rangatira picked up an a passive recorder left on the summit, presumably the same bird as XC599546. JFP calls twice 0:04-0:07 then again at 0:17 & 0:25, rest is all Black-winged Petrels
