Description
The grey-necked wood rail measures 38 cm (15 in) long[2][3] and weighs 460 g (16 oz). The upperparts are olive green to dark brown. The head and neck are medium-grey, blending into a brown patch at the back of the head. The eyes are red. The chest and flanks are rufous. The belly, rump and tail are black. Legs are coral-red. Males and females are similar. Immatures are similar to adults but belly sooty-black, flecked with buff. The similar but smaller rufous-necked wood rail (Aramides axillaris) has a reddish head and neck with a grey upper.[4]
