The one in the centre of the zoo? That is the aviary (divided into two sections) for Red-masked Conures and Polytelis Parakeets - or Conure Kingdom and Polytelis Paradise as I have been known to call it.
Ah, sorry I was not sure which one you meant. No, that is a pheasant pen (currently unoccupied). The Finch Aviary runs parallel with the boundary wall at the top of the zoo.
