During the breeding season, Great Egrets grow long feathers from their back called airgrettes.
The airgrettes were the feathers sought by the 19th and early 20th century plume-hunters for the millinery trade.
The magnificent Great Egret was very nearly hunted to extinction during the “Plume Bloom” of the early 20th century. Startling, cumbersome, and hideous, hats were fashioned with every manner of beautiful bird feather. Europeans were partial to exotic birds that were hunted the world over and they included hummingbirds, toucans, birds of paradise, the condor, and emu. The American milinery trade favored herons for their natural abundance. The atrocities committed by the murderous millinery led to the formation of the first Audubon and conservation societies however, what truly led to saving the birds from extinction was the boyish bob and other short hairstyles introduced in about 1913. The short cuts could not support the hat extravaganzas, which led to the popularity of the cloche and the demise of the plume-hunters.
Thousands of hummingbird pelts at 2 cents apiece
As absurdly ridiculous now as then
