African pygmy squirrels are bark gleaners and forage incessantly. Nectarivores, like gleaners, will frequently employ hovering during foraging. In "The Gleaners" (1857), for example, Millet portrays three peasant women working at the harvest. Gleaners are still in production under AGCO. Millet unveiled "The Gleaners" at the Salon in 1857. Millet sold "The Angelus" after his "The Gleaners" was sold at the Salon in 1857. "The Gleaners" provides evidence of Millet's role as a contemporary social critic. The Ancient Order of Gleaners was formed in 1894 in Caro, Michigan by Grant Slocum. He made a copy of "The Gleaners" "(Des glaneuses)" by Millet. "The Gleaners" is one of Millet's best known works. Varda's "The Gleaners and I" is notable in another regard, as well. The Gleaners had 43,000 members in 1994. In 1969 the Gleaners had 55,000 members. Hummingbirds and other gleaners are also sometimes attracted to the sap wells created by sapsuckers. A landmark solo bass album "The Gleaners" was issued by the ECM label in 2019.
