Aweeeee, is wuddle Fwanky angwee now?
Yes, you made a grammatical error. The singular and plural forms of words are (generally) not interchangeable (except for cases such as the word 'deer', which is both the singular and the plural form of the word).
There's no "the goose". The discussion is about multiple geese (specifically, Canada Geese).
Right. The correct terminology is 'Canada Goose', as you pointed out. However, you are nitpicking on an official terminology error in order to ignore the fact that Haitian illegal invaders are (illegally) killing and eating Canada Geese.
Worse than that, Haitian illegal invaders now make up roughly 25% of the entire Springfield (OH) population. What do you suppose such a sudden influx of illegal invaders does to the local housing situation, the local hospital situation, the insurance situation, and etc? Who do you suppose pays for all of those invaders to be there? If you were a resident of that neighborhood, how safe would you feel living there, suddenly surrounded by a bunch of invaders?
That's the whole point of your grammatical mistake.
Yup. Many people aren't aware that it's actually 'Canada' and not 'Canadian'. I wasn't aware of it until I got into birding/bird photography a few years ago.
Exactly.
You were responding to the mention of a group of birds... geese is correct in that context.
Why do stupid people like you comment on anything?
