NO, Uno's a BOY!!!

After much to-ing and fro-ing with photos to the Zoo Keeper, Rohan, he thinks Uno is a boy!

This is what Rohan said in his last email:

Looks like a male to me in this photo.  If you look closely at the brown part towards the tip of the abdomen you will see it is more rounded.  If it was a female it would be very pointed.  I saw the photos on your blog of the students involved in the radio cross yesterday.  Looked great.
Sincerely
Rohan

Sorry Uno. Apparently his rear end is flattened, not pointy like a girl's.

We're all learning!
