The most recent species kept in here, most of which will go back after the redevelopment were Victoria crowned pigeons, Pied Imperial pigeons, Nicobar pigeons, Mangrove kingfisher, WHite-naped pheasant pigeons, roul-roul partridge, Bali starlings, Asian glossy starlings, Grosbeak starlings and Luzon bleeding heart doves.
