Seems that this time the zoo started seriously with the new exhibits that should start to be constructed next month. At the begining of this month the zoo started to build a temporary exhibits for the animals that will be afected by the construction of the new exhibits for orangutans and the next phase of the Sahel exhibit for lions, elephants and giraffes (in theory mixed with scimitar-horned oryxs, dorcas gazelles and warthogs as these animals also go in this zone, but don't appear on the map that the zoo published of this zone).
The orangutan exhibit has been expanded from the initial plan and now it also will occupy the mandrills pit. The mandrills are going to be moved in a new enclosure that is being constructed in the "Montserrat Mountain", exactly in the spanish ibex exhibit. The spanish ibexs are not on display and I don't know what happened with this species.
The Sahel sabanna zone has also been modified and now the giraffes will have more space, the elephants a lake near a visitor's viewing point and the lion exhibit will be near the giraffes exhibit, with a pit as a separation like the Bioparc Valencia, to simulate that both species are in the same space. Animals affected with this new ampliation are the Pere David's deers and chitals, that will be moved in a new enclosure between the Doñana aviary and the petting zoo. The red deers and fallow deers may be also affected.
The deadline is for June 2015. At this time the new exhibit for Sumatran tigers should start....
On the former hippo exhibit has been built a new simple enclosure for the Galapagos tortoises, so maybe the ones that are inside the terrarium will be moved outside as in the current giant tortoises exhibit there are only two individuals.
Some other exhibits also seem that will be upgraded, as the "Plaça dels Lloros" (Square of the Parrots) that last time was nearly demolished.
No more new information about the dolphinarium.
If I visit the zoo next weekend I'll try to take some photos of all this of this updates, as I suppose that the construction of al temporary exhibits will be in a very advanced process.
