Here is the link to some of Raja’s pictures of prions of the 12 June Sydney pelagic. Based on tail pattern, facial pattern, half-collar and M intensity, we tried to identify and to put them into their subfolders accordingly. Bill shape was a difficult task. At least we are quite confident that there were no typical Broad-billed Prions and no typical Fulmar Prions out there. Some of the Antarctic Prions look heavy-billed and therefore may be Salvin’s. Slender-billed Prion indeed is not an easy bird to identify. Therefore there may be some errors in our ID suggestions.The last subfolder “All Prions – chronological” contains all selected pictures again – but un-identified and in chronological order. You may have a look at this folder first and try to get to your own unbiased conclusion. Comments welcome!

Further, there are some more pics of Black-browed, Campbell, Shy/White-capped and Buller’s Albatrosses, Northern Giant, Cape, Great-winged and Providence Petrels and White-fronted Tern. There is an interesting young Shy-type Albatross in the series. Its small size, slender bill and “innocent” face made us first think of young Buller’s.
