Jurassic Park Aviary

The Aviary is a cage pen where InGen housed Pterosaurs. Because the InGen scientists assumed that Pterosaurs love living near flowing water (for fish), the cage was build over a river.

Jurassic Park Franchise
A Cearadactylus aviary first appeared in the first Jurassic Park novel, and the idea was later ultimately used in Jurassic Park III.

Construction of Jurassic Park
During the planning, it was decided to put the Pteratops Lodge inside the paddock because the designers thought the inhabitors would be "safe" for tourists to interact with. However, this did not go well back then, it turns out the Cearadactylus were ill-tempered and attacked many maintenance crews that worked on it, thus leaving the lodge derelict inside.

This aviary was intended to appear in a fanmade Crysis mod. This was concept art:

Isla Nublar Incident
During the power outage, the dinosaurs escaped but the Cearadactylus were stuck inside. When Alan Grant, Lex Murphy and Tim Murphy were escaping the Cearadactylus during the outage, they took a raft and headed downstream towards the paddock. However, they had no idea what was going to happen. Consequently, the Cearadactylus attacked them, but luckily they were able to escape from them.

Napalm Bombing
It can be assumed that the lodge and the aviary where both destroyed when the Costa Rican Air Force bombed the island.

Film canon
The Aviary scene did not appear in the first Jurassic Park film. However, during the Lunch Scene in the VIP dinning room an art concept of the Aviary was displayed on one of the slideshow boards. It shows the outer structure of the visitor booth.

In Jurassic Park: The Game free flying Pteranodons are seen during the Isla Nublar Incident. This indicates that was an aviary hosting Pteranodons on Isla Nublar, though these Pteranodons were based off their later appearance in Jurassic Park III. The InGen Field Guide (from the Jurassic Park: The Game Deluxe Edition set) states that the Aviary was planned to be built in Phase 2 development of the Jurassic Park.

In The Lost World: Jurassic Park, a wall painting can be seen in the Worker Village. It clearly is a painting of the Park on Isla Nublar. In the left corner a Pterosaur can be seen, proving that an aviary was built or planned to be build in the Park.

In Jurassic Park III, an aviary is seen on Isla Sorna. It hosts a flock of Pteranodons.
