Marabou (historically spelled marabout) describes a certain type of down feather trimming. Although it takes its name from the marabou stork whose undertail down once provided the feathers,[1] white turkey feathers have been used as a substitute.[2] The advantage of marabou is that it takes dye well, making it a very versatile trimming for dress, and makes an effective substitute for fur.[1] While marabou has been widely used as a fashion trimming since the late 19th century,[1] it is also often used in fly tying for making up the lures ('flies') used for fly fishing.[2][3]
