condor and ostrich

Wikipedia mentioned that a -4 on one hole is called a Condor and -5 is an Ostrich. those names official?

Does it even matter because...is it even achievable?

Its like hole-in-one par 5 for the condor.

And hole-in-one par 6 for the ostrich.

Condor

Four under par (-4). This is the lowest individual hole score ever made, (par sixes do exist,[8] but are exceptionally rare and an ace has never been recorded on one). This would be a hole-in-one on a par five or a 2 on a par six. It has only been recorded four times in history, only once on a straight drive (for a record 517 yards) and never during a professional tournament.[9]
[edit]

Ostrich
A notional term for five under par (-5).[10] A hole-in-one on a par six. This score has never been recorded and is widely considered impossible, considering that par sixes are extremely long (and very rare).

I guess they can only be achieved in video games.

maybe will happen if the hole is a u shape
