**Mega rarity; about 3rd NJ record, and first photographed. Discovered earlier today by Melissa Laurino on the Cape May Whale Watch boat. 2nd year (sub-adult) bird standing on south jetty with mixed gulls and cormorants; flew around several times and rested on water briefly before returning to jetty. Mostly white Sulid with extensive blackish-brown flight feathers, greater upperwing coverts, and tail, including many trashed/worn feathers; dull blue-gray bill becoming yellowish toward tip, blackish at base; eyes dull yellow. Body plumage mostly dull white but with retained brown mottled rump, scattered dark flecks in wing coverts and back. At least 2 generations of flight feathers (trashed juv outer primaries, fresher inners). Distinguished from Nazca Booby by thinner, grayer toned bill. Gave an abrupt, nasal quack-like call several times when squabbling with other birds. 1000s of photos taken!
