On this day in 1984, a Buller's Shearwater was found on a pelagic trip off the Jersey coast. The bird was about 31 miles ESE of Barnegat Light, and remains a unique record. This species breeds on islands near New Zealand and the NJ record is the single North Atlantic record of the species. See Angus Wilson's Ocean Wanderers site for more info about Buller's Shearwater and its usual distribution.
David Sibley was the one who identified the shearwater, according to the account in Records of New Jersey Birds. I recently heard someone who was there at the time say that it was one of only two times he ever heard Sibley shout (the other was for a Mississippi Kite, which just shows how much times have changed).
