My recollection from the 1980s off NSW (Sydney & Wollongong pelagics) is that SGP was more common than NGP by about 2-1. In the last few years NGP have been more common than SGP off Sydney by 3:1 or so. Also, I think we almost exclusively see 1st year birds in recent years whereas we used to see some adult SGPs. I suspect that NGP is just as common now as it was in the 1980s but SGP is rarer. I assume it relates to changed mortality rates (perhaps long-line fishing mortality) , but I don’t have any evidence for that Cheers, David James Sydney ============================== =============================== To unsubscribe from this mailing list, send the message: unsubscribe (in the body of the message, with no Subject line) to: birding-aus-request@vicnet.net.au http://birding-aus.org ===============================
