Kessie first appeared as a chick in The New Adventures of Winnie the Pooh episode "Find Her, Keep Her". Kessie is cheerful, brave and eager to prove herself. Rabbit saved her from a snowstorm and she came to live with him. As a baby, she nicknamed him "Rabbie". Rabbit was very protective of her and initially did not want her flying. After she finally learned to fly, she migrated south for the winter, despite a reluctant Rabbit.
After she flew south, Kessie returned in the episode "A Bird in the Hand" as a young adult. In this appearance, everyone keeps an eye on her from being captured by Stan the Woozel and Heff the Heffalump.
In later appearances, she has reverted to being a young bird. After appearing in Seasons of Giving, Kessie was relaunched as a main character in The Book of Pooh, her first regular role. In the series, she is depicted as a puppet.
Voiced by Laura Mooney (as a chick), Stephanie D'Abruzzo (as a young adult) and most recently Amanda Maddock (as a puppet).
