Birdie (given name)
Birdie is a given name used in reference to an informal English diminutive word for a bird. Spelling variants include Birdee, Birdy, and Byrdie. It has been in use since at least the 1800s in the United States both as a nickname for various formal names such as Elizabeth and as a formal name. It was among the one thousand most popular names for American girls between 1880 and 1940. It then declined in popularity but has since increased in usage and has  ranked among the one thousand most used names for newborn American girls since 2021. Some commentators note that the name has risen in use for girls along with other names of a similar style that all exude cuteness and promote enjoyment, perhaps in reaction to serious times.
