Corvus tristis Lesson & Garnot, 1827

Medium-sized, long-tailed, scruffy crow with stout bill and bare pink facial skin; sparse nasal and rictal bristles. Plumage is variable, blackish to dark brown or grey, with slightly glossy wings and tail; iris light blue; bill grey; legs pink to grey. Sexes similar. Juvenile much paler than adult, pale grey-brown above, whitish on head and below, appearing rather bleached, with brown eyes and white bill; immature is only marginally less pale, with pink bill and feet (birds with mottled grey-brown eyes are probably immature); takes three years to acquire darker adult plumage.
