Same here, also as a former bassoonist - each note on the bassoon has extremely unique timbre, and I find it very easy to identify them.

No perfect pitch for other instruments.

You should try it on the baroque bassoon. It works there as well, despite the notes being a half note too low.

Or even the dulcian. The low C is very much the same as the bassoon low C despite being either too sharp or too low depending on school.
