Lowry Park keeps both in the same enclosure. I think your right though, I thought the one on the left was Maia, but I don't see the typical oak leaf pattern.
Last november, a zoo staff told me, that the reticulated giraffes died and has been replaced by a masai, a baringo (rothschildi) and another one (unknown origin? - don't remember). It looks as if those on the picture are the later two.
rothschildi I think is on the left. If the one on the right is not a reticulated then I don't know what it is. After some digging I found out that the massi had arrived after this photo was taken. I'll have to find video from someone else post and link it here on their recent arrival of the massi, which i many have a photo of from a couple weeks ago. EDIT: ok so I found the link original posted by BeardsleyZooFan here But watch the youTube Video here
