Well I realised it was a joke at least a minute before noticing the date and I did not look at the link to the alleged suggestion. But I might still do so, if someone tells me it is humorous. The trivial suggestion that: “having to take Australian Raven, Little Raven and Torresian Crow off of my year and life lists” would be in some way an important consideration as a disadvantage, relative to the huge aspect of contradicting biological principles, was a pretty huge clue that it was a joke. That was enough for me. Then the date clinched it. Though I am curious at Jeff’s comment “three ssp freely cohabiting in Victoria”. I thought “ssp” was subspecies and “sp” meant species. Please explain if I am wrong in my abbreviation use, but if not, then Jeff’s comment (I expect just a slip) would be ironic.
