I searched Google.com on
"Guy Graves" +zoo +Louisville
 
Here is a bibliography but I don't know how old it is so you may need
to search for more recent things:
http://www.fs.fed.us/r2/nebraska/gpng/literature/litferret.html
 
http://leader.louisville.edu/edtl/brown/EDTP%20653%20syllabi.pdf
mentions him in relation to "conservation center", "black footed
ferret project"
 
So, back to Google
Results 1 - 10 of about 335 for "Louisville Zoo" +"Conservation
Center". (0.24 seconds)
and one of the top ones is
http://www.louisvillezoo.org/conservation/stories/con-ferrets.htm
which should easily get you some contact info
 
There!  Now you also know a LOT about easy searching which should
help you find things in the future.  Now you can fish for yourself
very easily.
 
Another tip: if you select the "cached" version in Google then the key
words will be highlighted, allowing you to skim to the sections needed,
plus sometimes it gets people into articles which are no longer available
or may be otherwise inaccessible.
 
Searching is EASY once a person gets used to the tricks enough that they
become habitual.
 
If he has moved to a different location then asking someone at this zoo
should help you find that zoo, foundation, project, university, etc.
unless he has retired in which case you can ask if they can forward a
letter with your contact info while also considering approaching other
experts (which makes sense, anyway, if you have not already done that).

Clover, I LOVE your nursery rhymes.  You bring marvelous poetic imagery
into them.

Rebecca answered a question for me about BIG!  Now I know why the
evidence disappeared that the Earth was once flat but that ferrets in
flying saucers pulled it into a globe like puffing a layered flatbread
by pulling on it with giant bungee cords.  I'll bet they had fake
space/sea monsters they put near the edges beforehand to protect
mariners, too.  Hey, a ferret isn't the mascot of the Massachusetts
Colonial Navy just because of rodent protection!  Shhhhh!  That's a
secret!  Bill, you cad, you!  Undermining scientific inquiry. ;-)
