Factual error: The film is explicitly set on the east coast of Australia. However Nigel is a Brown Pelican (Pelecanus occidentalis), a species only found in the Americas. The only pelican species found in Australia is the Australian Pelican (Pelecanus conspicillatus) which is mainly white, with black wing tips. If a Brown pelican was somehow transported to Australia and subsequently escaped into the wild, it would have been caught and destroyed under Australia's strict quarantine laws.

Trivia: The kid in the waiting room is reading a comic with Mr. Incredible on the cover, from the Disney/Pixar movie The Incredibles. (01:19:25)
Chosen answer: Nigel is a pelican - he appears to be modelled on a Brown pelican (although that particular species is not actually native to Australia).
