In 1886, 5 million birds were estimated to be killed for their feathers. They were shot usually in the spring, when their feathers were colored for mating and nesting. The plumes, or aigrettes, as they were called in the millinery business, sold for $32 an ounce in 1915— the price of gold. Millinery was a $17 million a year industry that motivated plume harvesters to lay in watch of nests of egrets and many colored birds during the nesting season, shoot the parents with small-bore rifles, and leave the chicks to starve. Plumes from Everglades wading birds could be found in Havana, New York City, London, and Paris. Hunters could collect plumes from a hundred birds on a good day.
