Species accounts, Liewards #13 R.P. Burton 1866 21 June. Sooty Storm Petrel Laycan No birds have as yet been seen (13 Tuns) but one skeleton, or rather dried up carcass, was found by the layman, with distinctly forked tail, distinguishing it from Bulwer's Petrel. The season is probably only two lute for these Storm Petrels to be on the island.
