I've been checking all your posts about your trip to this zoo park... and well, I'm surprised to see so many rare species on you photos. I mean, licaons (wild african dogs) and babiruses are just too rare to be commonly in zoos; that's just impressive. Pretty much the same to that odd ibis, or the pingueon (I guess it's some south assian species, but I don't recognize it). I figure out this zoo may be one of the most important among its kind.
About the otters, I find them really amusing; I love how playful is this specie. Anyway, are those otters from America? they look different from european otters.
I look forward to more of your zoo posts. Those pics are neat ;-)
