Gerald is a character in Finding Nemo, and one of the film's numerous antagonists.
Finding Nemo
Gerald is a pelican who is a friend of Nigel.
In the film, Gerald scoops up Marlin and Dory after the two fish arrive at the Sydney Harbour. Marlin thinks he and Dory are about to be eaten, so they lodge themselves in Gerald's throat, making him choke. The other pelicans, including Nigel, witness Gerald choking, and Nigel flies over to help his friend. Gerald opens his mouth to reveal Marlin and Dory to Nigel, who then hits Gerald's neck, making him spit out Marlin and Dory, who then try to escape from becoming a food for pelicans.
