Pelican

Pelicans are water birds with long pouched bills for catching prey. They were members of Aslan's army.

The Lion, the Witch and the Wardrobe (BBC serial)
A single pelican is seen among the winged beasts (a cockatrice, an eagle, a Pegasus, a winged panther, and a gryphon) in Aslan's army. They first appeared when the Pevensies and the Beavers arrive at the Stone Table.

After Peter defeated Maugrim, the pelican and the other flying creatures were ordered by Aslan to follow the other wolf and rescue Edmund. When they swooped in that night on the White Witch to attack, the pelican pecked at Ginarrbrik with its bill. Once they succeeded on their mission, they flew back to the Stone Table with Edmund.

When the White Witch came to the Stone Table the next day, the pelican and the other winged animals flapped their wings and squawked/roared/whinnied at her.

When the battle began, the flying beasts (including the pelican) began flapping their wings and squawking as the White Witch's Army approached, starting the battle. During the battle it, the eagle, and the cockatrice, swooped at the White Witch (first the eagle, then the pelican, and finally the cockatrice) before Ginarrbrik shooed them off with his whip. Upon the Witch's defeat, the pelican helped the cockatrice drive some of the ghosts and demons in her army away into a crack in a cliff.

The pelican and the other winged animals were last seen flying to the castle for the Pevensies' coordination.
