A bird of the family Acanthidae (illustration) in the order Passerine. It is about 10 cm long, and much smaller than a sparrow. Sexes are the same color. The front and back of the eyes and the beak are crimson red, the back is gray-brown, and the underside is light brown. The lower back and tail are black, making them very conspicuous when flying. It is found along the southern edge of the Sahara Desert, across the center of the African continent, from Ethiopia to Senegal. It lives in scrub forests in semi-desert areas, and also likes thorny areas around agricultural fields. It breeds monogamously. It builds its nest at the base of grass or shrubs using the tips of dead grass leaves, with an egg-shaped roof. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
