Birdie the Early Bird was the first identifiably female character used in McDonald's commercials, introduced in 1980 to promote the company's new breakfast items. She is a yellow bird wearing a pink jumpsuit and flight cap and scarf. In the ads she is frequently portrayed as a poor flyer, and somewhat clumsy in general.
Birdie's origin is explained in one old commercial: A giant egg falls from the night sky into McDonaldland, Ronald McDonald decides to show the egg love. When the egg hatches and Birdie emerges she is so so happy that she has already made friends and decides to stay in McDonaldland.
Birdie is voiced by Russi Taylor.
