Sorry for the late reply to your answer to my questions. Pleased to see that you are happy to follow the trends if it is to be the way in the future.
Even if you are still not totally comfortable with what you thought was a somewhat contrived tick of your Blue Petrel there is always the possibility of another sighting in the future to put you at ease

The Prions..... you probably should go to the next release when it occurs, at least you can be totally satisfied that you have correctly ID'ed a Salvin's!.
As for Sirocco... He is a great ambassador but for me, totally off the menu during his PR work..... he is a pet one, let's be honest.
However when he retires to some offshore island then he could be back on

Cheers.
