A group of lions is a “pride.” A bunch of birds form a “flock” (usually, anyway — some birds get special consideration). But what do you call a group of giraffes? As it turns out, the proper collective noun is a “tower.” “A tower of giraffes” is one of many fun turns of phrase reserved for animal groups; you can also properly refer to “a parliament of owls,” “a murder of crows,” and even “a confusion of wildebeest.”
According to the BBC, many of these names date back to a publication called “The Book of Hawking, Hunting, and Blasing of Arms” (commonly called “The Book of Saint Albans”), which was penned by Englishwoman Juliana Berners way back in the 1400s. The book is so old that Berners is thought to be one of the first female authors (if not the first female author) of a printed book in the English language.
