The Eaglet is a character appearing in Chapter 2 and 3 of Alice's Adventures in Wonderland, a reference to Edith Liddell, Alice's sister.
In this passage Lewis Carroll incorporated references to everyone present on the original boating expedition of July 4, 1862 during which Alice's Adventures were first told, with Alice as herself, and the others represented by birds: the Lory was Lorina Liddell, the Eaglet was Edith Liddell, the Dodo was Charles Lutwidge Dodgson, and the Duck was Rev. Robinson Duckworth.
