<<I was under the impression that there is actually no record of the effects of pole reversal on animal populations and that no one knows if this pole reversal process will take a hundred years, a thousand years, or that it will happen overnight. In fact, this will be a learning process for everyone.
Am I wrong? Is there documented evidence?

You are right but, we do know a little about the ball park now.
There is a collection of info in wikipedia.
I understand it is widely variable on reversal-- One was calculated to only 4 years. Others 1000's of years--whatever that means. The body of studying magnetic pole reversal is young.
We postulate harmful effects owing to increased UV light reaching the ground along with damage from high-speed particles that would have been deflected. What I am comfortable in saying is thus far with what we have researched, science cannot find any extinction of species which can be tied/correlated to a magnetic pole reversal.
NOTE: Climate change is not magnetic pole reversal some of the links at wiki refer to wobble/precession of the true north pole and get into climate cycles, but as I said the wobble of the physical north pole is not a player per se in magnetic flux reversal.
