At the turn of the 20th century, vast numbers of birds were being killed in order to provide feathers to decorate women's hats. The fashion craze, which began in the 1870s, became so prominent that by 1886 birds were being killed for the millinery trade at a rate of five million a year; many species faced extinction as a result. In Florida, plume birds were first driven away from the most populated areas in the northern part of the state, and forced to nest further south. Rookeries concentrated in and around the Everglades area, which had abundant food and seasonal dry periods, ideal for nesting birds. By the late 1880s, there were no longer any large numbers of plume birds within reach of Florida's most settled cities.
