Nothing to photograph at this point, the site is still flat land. Anyway most of the site can't be seen from public areas, so there won't be much if any photos of the construction.
Forgive if this information is in another thread, but have they released any conceptual art or descriptions of what the exhibits and highlights of the new bird park will be? Are they essentially replicating what already exists in the current park?
See this thread: WRS Mandai expansion plans There are various links in the thread with videos, drawings, etc. There are also some photos in the gallery (Singapore Other) of a model on display. Singapore - Other | ZooChat
A small update that Jurong has gotten a new pair of Shoebills and they're on display at the Wetlands exhibit.
There have been rumours of that for years. Would be pretty cool if it happens but I'm not holding my breath too much. (Although if anywhere were to get them, Jurong is a strong contender).
Jurong came close to getting the eagles some years back and have continued working quietly to negotiate a deal. Fingers crossed.
Background on how Jurong became involved with this specie: Endangered birds rescued from wildlife trade by Singaporean
How large was the original group (info on sex ratios?) when entrusted to Jurong? The recovered group was 76.33 strong and heavily skewed towards males.
An interesting article from the BBC here about Jary, a male great hornbill at Jurong, who has been fitted with a 3D-printed prosthetic casque after much of the original tissue was destroyed by cancer. The prosthesis will remain in place until the new casque grows through. The article is included below: 3D-printed solution for cancer-hit hornbill
Jurong now has Black-faced Spoonbills. 2 pairs from Japan are now on display in the wetlands, opposite the Shoebills. There are also around 10 male Santa Cruz Ground-doves in one of the side aviaries of Wings of Asia.
