Abstract

The importance of grit in avian digestion has been recognized for at least two centuries (Spallanzani, 1783 [cited in Westerskov, 1965]). Grit is in the gizzards of most birds that eat plant parts (Meinertzhagen, 1964; Farner, 1960) and of many that eat invertebrates (Mayoh and Zach, 1986; Barrentine, 1980; Peterson and Ellarson, 1977; Jenkinson and Mengel, 1970; Barlow et al., 1963). Many studies have shown that, among avian species that use grit, most individuals have grit in their gizzards (Table I).
