The tuaimeo (friendly [shy] ground-dove, Gallicolumba stairi) is a medium sized bird, approximately 10 inches (in)(26 centimeters)long (Watling 2001, p. 117) and weighing between 3.6 to 5.8 ounces (102 to 165 grams) (Baptisa et al. 1997, pp. 180–186). Males are generally larger than females (Baptisa et al. 1997, pp. 180–186). Friendly ground-doves are mostly rufous and dark brown with a black bill and with purplish red legs and feet (Baptisa et al. 1997, p. 185; Watling 2001, p. 117). Adult males have purple wing coverts, white feathering on lower breast, and gray crown (Pyle et al. 2017, p. 15). Adult females have brown wing coverts, lack the white feathering on the lower breast, and have brown crowns (Pyle et al. 2017, p. 15). Juveniles resemble adult females (Watling 2001, p. 117; Pyle et al. 2017, p. 15).
