Description
The croaking ground dove is long. Males weigh about and females . The adult male's head is bluish gray, and its upperparts brownish gray. The central tail feathers are darker gray, and the outer ones black with white tips. The closed wing shows a dark bar and lines of dark spots. The breast and underparts are mauve pink. The eye is red with a white outer ring and is surrounded by bare yellow skin. Its fairly long bill is bright yellow near its base. The adult female's head is brown and the wing markings are less intense than the male's. Juveniles are similar to the female but their feathers have buffy tips.[
