It is closely related to the Barbu d'Anvers, but is distinguished from it by its small, backswept crest of feathers as well as its triple spiked rosecomb.

The Barbu de Boitsfort is a rumpless variation, the only difference being that it lacks the uropygium, the part of the anatomy that carries the tail.

It was created by Antoine Dresse at the estate of La Fougères at Watermael-Boitsfort in the early years of the twentieth century, or, according to one source, in 1915.

[1][5] In number, the Barbu de Watermael is today the second bantam breed in Belgium, with a population of 764 in 2010; it was classed as "in danger" in that year.

[3] The Barbu de Watermael is one of the smallest of all bantams: males weigh 600–700 g and hens 450–550 g.[2] It has a narrow backswept crest, a three-part beard and a unique spined rose comb.
