Birdie

Birdie is an English diminutive pet form derived from the word bird, itself tracing back to Old English bridd, meaning a young bird or chick. It emerged as a given name in the nineteenth century, when nature-inspired and affectionate nickname names became fashionable in Britain and the United States. It also functions as a pet form of names beginning with the syllable Bir-, such as Bertha or Bridget, through sound association rather than strict etymology. Related forms include Birdy and the Scottish Gaelic name Bride.
