Temaiken tends to spend lots of money in every exhibit, that might be reason why it does not have too many species. These flying foxes are the only ones in Argentina, and live in this heated enclosure.
And I might add is one of the very best and most compelling bat exhibits I've ever seen--lots of activity,with a large group of bats that have been target trained. It reflects the overall high quality of nearly every exhibit and public facility at this impressive zoo.
